Sliding door problem

DESCRIPTION
Each power sliding door is equipped with a Power Sliding Door Control Module (1) (PSDM). The PSDM is mounted directly to the inboard side of the power sliding door drive assembly (2) with two retaining screws. The drive assembly is mounted to the body near the bottom of the sliding door in the track cavity with the use of five retaining nuts. The wire harness and chain link track and the power sliding door drive assembly are visible with the door open in the lower door sill area.
Software technology has enabled the PSDM to detect resistance to door travel. This allows the power sliding door to stop and reverse direction any time an obstruction is felt or any of the command switches are operated. Battery voltage is supplied to the power sliding door system through a 40 amp fuse, located in the Totally Integrated Power Module (TIPM) assembly. The power sliding door lockout switch located in the front overhead console prevents opening or actuation of the power sliding door system when activated. In the unlikely event that the power sliding door system develops a fault, the power sliding door can still be operated manually from the interior or exterior door handle similar to a standard manual sliding door.
NOTE: It may be possible to generate Sliding Door Diagnostic Trouble Codes during normal power sliding door operation. Refer to the appropriate power sliding door diagnostic information for a complete list of diagnostic routines.
OPERATION Battery voltage is supplied to the power sliding door system through a 40 amp fuse, located in the Totally Integrated Power Module (TIPM) assembly. With the push of a power sliding door open/close command switch (key fob, overhead console or B-pillar mounted) a signal is received by the Power Sliding Door Control Module (PSDM). The PSDM receives this signal via the Controller Area Network (CAN) Data Bus circuit. The PSDM then signals the power sliding door cinching latch to release the door to the unlatched and movable position. The power sliding door drive assembly motor then starts an open cycle.
The overhead power sliding door switch is mounted in the front overhead console of the vehicle. The switch has resistors in parallel of 1.76K ohms, 3.17K ohms and 15K ohms. When pressed, the switch will have a nominal resistance of 1.76K ohms for the right sliding door button, 3.76K ohms for the left sliding door button and when not pressed, the switch will have a nominal resistance of 15K ohms.
The status of the overhead power sliding door switches is continually monitored by the circuitry within the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN). The instrument cluster receives input messages from the overhead power sliding door switches over a hardwired connection. Whenever the instrument cluster receives an input from the overhead power sliding door switches it sends a function command signal to the selected PSDM. This message from the cluster to the PSDM is delivered via the Controller Area Network (CAN) data bus.
The B-pillar switch is located on the lower B-pillar trim panel and allows the rear occupants to power open or close the sliding doors. The B-pillar switch is an R-Mux switch that has a resistance of 3.6K ohms and 16K ohms depending on switch position. When pressed the B-pillar switch will have a nominal resistance of 3.9K.
The B-pillar switches are hardwired to the Totally Integrated Power Module (TIPM). The PSDM receives the message for operation status via the Controller Area Network (CAN) data bus. If all the necessary conditions are met the PSDM will then perform the requested operation. The B-pillar switch lockout feature must be disabled and the sliding door must be unlocked in order for the B-pillar switch to function.
The FOBIK switch sends a signal to the Wireless Ignition Node (WIN). The PSDM receives the message from the WIN for operation status via the Controller Area Network (CAN) data bus. If all the necessary conditions are met the PSDM will then perform the requested operation. The vehicles theft alarm must be disabled and the sliding door must be unlocked in order for the FOBIK switch to function.
When one of the PSDMs receives a command signal it checks the following:

1. PRNDL Status
2. Vehicle Speed Status
3. Ignition Status
4. Vehicle Theft Alarm Armed/Disarmed Status
5. Sliding Door Latch Status
6. Sliding Door Full Open Status
7. Ambient Temperature
8. Door Lock Status
9. Sliding Door B-Pillar Switch Lockout Status
10. Sliding Door Window Up/Down Status

If the appropriate conditions exist the PSDM will send a command signal to the selected Rear Door Control Module (RDCM) so the sliding door can be latched/unlatched as needed. This command signal is sent via the CAN data bus. Once the PSDM senses the latch function it will power the motor on the power sliding door drive assembly to open/close the sliding door as requested by the overhead power sliding door switches.
During the door cycle, if the PSDM detects sufficient resistance to door travel, such as an obstruction in the door's path, it will immediately stop door movement and reverse door travel to the full open or closed position. The ability for the PSDM to detect resistance to door travel is accomplished by hall effect sensors detecting the door motor speed.
The PSDM has the ability to learn. Anytime a door is opened or closed using the power sliding door system the module learns from its cycle. If a replacement power sliding door component is installed or a door adjustment is made, the module must re-learn the effort required to open or close the door. A learn cycle can be performed with a complete cycle of the door, using any one of the command switches or with the use of a scan tool. (Refer to 08 - Electrical/Power Sliding Door - Standard Procedure) for detailed instructions.
The power sliding door system is designed with a number of system inhibitors. These inhibitors are necessary for safety and/or feasibility of the power sliding door system. The power sliding door system inhibitors are:

1. The power sliding door must be in the full open or closed position in order for the power sliding door system to start a normal cycle. If the door is not in this position (based on the input from the switches integral to the cinching latch assembly) the PSDM will only perform a power open cycle.
2. The transmission must be in park or neutral in order for the power sliding door system to start a cycle.
3. The front overhead console lockout switch must be in the "UNLOCKED" position in order for the power sliding door systems B-pillar switches to function.
4. If multiple obstacles are detected during the same power open or close cycle the power sliding door may go into full manual mode.
5. If severe Diagnostic Trouble Codes (DTC) are stored in the PSDM the power sliding door may go into full manual mode.
6. Due to the high pressure created in the passenger compartment with the blower motor on high, the power sliding door may not complete a power close cycle unless a window is cracked, allowing the pressure to escape. This situation will only be experienced on some vehicles, or vehicles with brand new side door weather seals installed.

The hard wired circuits for the power sliding door switches may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. However, conventional diagnostic methods will not prove conclusive in the diagnosis of the electronic controls and communication between other modules and devices that provide some features of the power sliding door system. The most reliable, efficient, and accurate means to diagnose the power sliding door switches or the electronic controls and communication related to the power sliding door system operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

POWER SLIDING DOOR SYSTEM WARNINGS

WARNING: Always disconnect the negative battery cable before attempting any power sliding door system service.
WARNING: Extreme care must be taken to prevent objects from entering the doors path once the door reaches the cinch motor contact (approximately 1 inch before fully closed). Never place objects in the power sliding door when cinching closed. The obstacle detection function is inoperative during the cinch phase and damage to the vehicle, power sliding door system or components and/or personal injury may occur.
WARNING: Never attempt to enter or exit the vehicle while the power sliding door is in motion. You could damage the power sliding door system or components and/or cause personal injury.
WARNING: Never attempt to drive away with the power sliding door in motion. You could damage the power sliding door system or components and/or cause personal injury.

The proper way would be to look at a wiring diagram an test the electrical circuit's with a DVOM - digital volt ohm meter . Do you know how to test automotive electrical circuit's ?

Rear Side Door Actuator Control Module
The rear side door actuator control module is capable of on-board diagnostic functions described in On-Board Diagnostic Features . The rear side door actuator control module monitors the door position at all times including during manual operation. After activating the on-board diagnostic modes, loosing battery voltage, or ground to the rear side door actuator control module the Power Sliding Door (PSD) Re-Initialization procedure must be performed in order for the rear side door actuator control module to correctly determine the door position.
Power Sliding Door System Description
The power sliding door system(s) can operate correctly only if the power sliding door is in proper mechanical condition. Any mechanical problems will affect the power sliding door operation and must be repaired before attempting to diagnose the power sliding door system. Manually open and close the power sliding door to determine if the door moves smoothly and without excessive resistance or binding. The power sliding door must also latch and unlatch without the use of excessive force. At any time during power sliding door open or close operation, excessive resistance to the door movement will cause the power sliding door to stop and reverse the direction of travel.
The power sliding door will operate only when the power sliding door on/off switch in the overhead console is in the on position. At anytime during power sliding door operation the on/off switch may be turned to the off position and the system will quit any function in process. The power sliding door will not open unless the transmission shift lever is in the park position and the door is unlocked. When the sliding door security lock is in the locked position the power sliding door will not open from the inside. The power sliding door close function will operate when the vehicle is in gear. The power sliding door module uses the VSS signal to determine if the vehicle is moving during a power sliding door close function. The momentum of the vehicle moving forward adds resistance to the door closing operation. When the rear side door actuator control module determines the vehicle is moving forward while closing the door, current flow through the actuator motor is increased instead of being reversed. The VSS signal circuit is supplied battery positive voltage through a resistor then monitored within the rear side door actuator control module. The VSS signal circuit is then pulsed to ground, or pulled low by the powertrain control module in relation to vehicle speed. The sliding door alarm will sound repeated short tones whenever the power sliding door system is turned on and the door is open while the transmission is out of park.
When the power sliding door system is on and manual operation of the power sliding door is detected the rear side door actuator control module activates the power assist feature. When the power assist is activated the power sliding door will continue to open or close without any further manual effort.
The power sliding doors may be operated using the Remote Keyless Entry System. The keyless entry transmitter will have one OPEN/CLOSE button with a van symbol on it for each power sliding door. The power sliding door ON/OFF switches in the overhead console must be in the ON position in order to operate the power sliding doors using the keyless entry transmitter. When a right hand power sliding door OPEN/CLOSE function is activated using a keyless entry transmitter the exterior lights will flash once indicating the RKE module has received the OPEN/CLOSE command. When activating a left hand power sliding door OPEN/CLOSE function with the keyless entry transmitter the exterior lights will not flash.

On-Board Diagnostic Features
The left and right power sliding door systems operate as independent systems. The on-board diagnostic modes are entered and operate the same in both systems.
The power sliding door systems are capable of the following on-board diagnostic functions:
• Diagnostic Mode 1: An audible signal indicates the diagnostic trouble codes stored by the rear side door actuator control module.
• Diagnostic Mode 2: An audible signal indicates when inputs to the rear side door actuator control module are active.
• Diagnostic Mode 3: Performs an output test of the sliding door unlatch actuator.
Entering On-Board Diagnostics
The on-board diagnostic modes can only be entered in a sequential order from modes 1-3.
• Enter the right power sliding door system on-board diagnostics using the right B-pillar open/close switch and the right on/off switch in the overhead console.
• Enter the left power sliding door system on-board diagnostics using the left B-pillar open/close switch and the left on/off switch in the overhead console.
1. Both power sliding doors must be closed and in the latched position.
2. Place the ignition switch in the OFF position.
3. Place the on/off switch in the overhead console to the OFF position.
4. Press and hold the B-pillar power sliding door open/close switch.
5. While holding the open/close switch, operate the on/off switch through 10 ON and OFF cycles within 10 seconds stopping in the on position.
6. The sliding door alarm will sound 1 long tone indicating diagnostic mode 1 is active.
Diagnostic Mode 1
Upon activating diagnostic mode 1, DTCs will begin to be signaled by the sliding door alarm. The DTCs are 2 digit codes and the codes are represented by the number of buzzes for each digit of the code number. For example a DTC 12 is represented with the following sequence: buzz, pause, buzz, buzz, long pause. Each DTC will be signaled 3 times before proceeding to the next DTC. Refer to Diagnostic Trouble Code (DTC) List . The DTCs will continue to be repeated in this manner until the on-board diagnostics are exited or mode 2 is entered. When exiting the on-board diagnostics all stored DTCs will be erased from the rear side door actuator control module memory.

If the battery had been disconnected the doors must be re-homed before they can work properly. The power sliding door control unit must relearn the doors home position so it can use the revolution sensor to keep track of the doors position when moving. To re-home the doors do this: erase the sliding door DTC's by removing No. 7 fuse from the under-dash fuse box then reinstall it. Turn off the main switch for the doors. Make sure the key is in lock (0). Fully close the sliding doors manually. Then turn the ignition switch on (II). then turn the main switch on. Test the power sliding door operation. See if this works. Also there is a problem with moisture freezing on the door position switches which causes the doors to malfunction. -hope this helps. let me know how it goes.

it seems like this is the motor that operate the sliding door...it might just be the switch on the door where you push the button if that isnt the only button that cant operate what it is suppose to operate...the motor will be locted inside the door

Replace the wire track harness in the lower door opening.

Verify the wiring harness which passes under plastic step & carpet at front passenger side. This wiring harness goes from the firewall to the pillar on the right side and some have crimped connectors in them to act as junction between two or more wires (ususlly the 12volt feed), which deteriorate with time, especially with Salt & Water. Then the electric sliding door stops working and even driver the electric seat can loose power.

look under the hood there is a small fuse box located next to the battery that has a fuse that operates the sliding door also make sure the switch on the dash above the sliding door switches isnt off

Have you tried (with engine off) taking the left bottom fuse out(I believe it's "TAIL" keep it out for a miniute, then put it back in and crank the engine. push the side door button and open it. Wait a few seconds then push button to close. Make sure your battery is fully charged.
The fuse box is in the glove compartment in dash on left hand side.

Sounds like something isn't right.Try to disconnect the battery for a few minutes and see if that helps.Some times the ecu gets haywired and disconnecting the battery might reset it.And if it is the original battery you might want to get it tested.
