BCM - body control module system , or switch input of some kind is ! Do onboard diagnostic's to fine the problem !
On-Board Diagnostic Features
This vehicle is equipped with an on-board diagnostic feature capable of performing the following functions:
• Feature Customizing
• Displaying DTC codes
• Clearing DTC codes
• Input/Output Diagnostics
Feature Customizing Mode
The feature customizing mode is used to configure the BCM to function in various applications. The BCM can be customized to change the following vehicle functions:
• Interior Lighting Features
• Door Lock System
• Keyless Entry System
• Content Theft Deterrent System
In order to enter the feature customizing mode perform the following steps:
Turn the ignition switch to the LOCK position.
Remove the BCM PRGRM fuse.
Turn the ignition switch to the ACC position.
When entering the feature customizing mode, the BCM first identifies what type of BCM is installed on the vehicle by flashing the fasten seat belts indicator and sounds the chime 2, 3 or 4 times depending on the type of BCM used on the vehicle. There are 3 different types of BCM that can be installed on the vehicle based on the vehicle option content that matches the BCM capabilities. Ensure that the BCM installed on the vehicle is compatible with all of the features on the vehicle. Refer to Body Control System Description and Operation for BCM identification.
For more information on features that can be customized, refer to Personalization Description and Operation in Personalization.
Displaying DTC Codes
The DTC codes can be displayed by entering the diagnostics mode. Clearing DTC codes and Input/Output Diagnostics are also available in the diagnostics mode.
Complete the following steps in order to enter the diagnostics mode:
Turn the ignition switch to the LOCK position.
Remove the BCM PRGRM fuse.
Turn the ignition switch to the ACC position.
Quickly turn the ignition switch from the ACC position to the LOCK position then back to the ACC position within 1 second.
The BCM will enter the on-board diagnostic mode and flash the fasten seat belts indicator and sound the chime equal to the number of DTCs stored in the BCM memory. If no DTCs are stored, the BCM will not flash the fasten seat belts indicator or activate the chime.
The BCM flashes and sounds the first DTC with the lowest number, pauses, then continues with the next DTC until all of the DTCs are read. With a DTC 1, the BCM will only sound the chime once, and the fasten seat belts indicator may not flash. Once all of the DTCs are read, the BCM repeats this sequence 3 times.
Important: If the fasten seat belts indicator does not flash, and the chime does not sound, complete the following procedure in order to confirm that the BCM has entered the diagnostics mode:
Ensure that all of the vehicle doors are closed.
Open and close any vehicle door.
Fasten and release the driver seat belt.
The BCM sounds the chime when receiving an input signal such as Drivers door, Passengers door opening or turning on the courtesy lights when the BCM is in the diagnostics mode. Make sure these inputs are working correctly in order to prevent a false diagnoses.
If the BCM does not sound the chime upon opening a door or turning on the courtesy lights, repeat Step 1 of Entering the diagnostics mode. If the BCM does not enter the diagnostics mode, then refer to Cannot Enter BCM Diagnostics .
Clearing DTC Codes
After entering the diagnostics mode press and hold the Unlock switch for 4 seconds. The BCM will erase all history DTC codes. If a circuit is still shorted, the BCM will immediately store a history DTC code.
Input/Output Diagnostic Mode
After the BCM reads all of the DTCs in the memory, the BCM enters the Input/Output Diagnostic Mode.
The BCM flashes the fasten seat belts indicator and sounds the chime once when any of the following inputs are activated:
• Courtesy lamp switches
• Door lock cylinder switches
• Driver door ajar switch
• Headlamp switch
• IP compartment lamp switch
• Keyless entry request for door lock/unlock
• Keyless entry request for the alarm (RPO UA6)
• Passenger door ajar switch
• Power door lock switches
• Liftgate ajar switch
• Sliding door ajar switches
• Shock sensor
• Hazard switch
Perform the following procedure in order to test the BCM outputs:
Ensure that the BCM is in the diagnostic mode. Refer to Entering On-Board Diagnostic Mode.
Cycle the interior light switch ON then OFF.
The BCM will enter the Output Diagnostic Test Mode 1.
Each cycle of the interior light switch ON/OFF will select from following test modes depending on BCM type:
• Test Mode 1-- De-activates the courtesy lights output and removes power to all of the interior lamps.
• Test Mode 2-- Activates the courtesy lights output and provides power to all of the interior lamps. Interior lamp override switch must be ON.
• Test Mode 3-- Activates the courtesy lights output and turns ON all of the courtesy lamps. Interior lamp switch must be ON.
• Test Mode 4-- Activates the theft deterrent relay for 1 second and turns ON the headlamps. BCM type 4 only.
• Test Mode 5-- Energizes the horn relay for 25 ms. BCM type 4 only.
• Test Mode 6-- Turns on the security LED indicator. BCM type 4 only.
• Test Mode 7-- Turns off the security LED indicator. BCM type 4 only.
When the BCM completes all test modes, the BCM will repeat the test mode sequence.
A normal function of many modern "thinking" cars.
If you need it to remain unlocked you could leave a window open or leave a door on the first catch or leave the spare key in the ignition...
SOURCE: back side doors will not respond to auto key unlock and lock
Look inside back door frame and find child safety lock port. Set child safety lock to off setting.
SOURCE: Radio, Key auto door lock/opener, interior lights not working.
Most likely is a fuse. There is a fuse box at the end of the right side of the dash. Open front passenger door and there is a cover that says fuses on the end of dash. There is also a fuse box located under the hood at the right front of engine compartment. It should have a cover with a round knob in the middle of it .Unscrew the knob to remove cover.
SOURCE: Driver and Passenger auto door locks are inop.
Sounds like bad wiring, or bad door lock actuators. Check for power while locking/unlocking the doors.
SOURCE: The auto-unlock is not functioning, but the auto-lock is.
ok the switch on the drivers side not working is the problem,its not allowing the cicuit to be completed.you may want to check the passenger side lock actuator.
