Top 20 2005 GMC Canyon Questions & Answers

Question edited for clarity. Question moved to model category. Video help is the best way.

The engine compartment fuse block is located on the driver's side of the engine compartment Check fuses 21 and 42. https://my.gmc.com/content/dam/gmownercenter/gmna/dynamic/manuals/2005/gmc/canyon/2005_gmc_canyon_owners.pdf

The problem with most newer vehicles is that many functions are controlled by computer modules which are prone to malfunction when spikes occur in the electrical system. Often this is a temporary condition and the computers can be reset by disconnecting the negative battery cable for a few minutes and then reconnecting it. However, if the problem is persistent or keeps occurring, the faulting module (in your case the TC module) will need to be replaced. Most GM vehicles have a button in the vehicle that will disable the system (see the owners manual), but if one is not is available or is not working properly, check out https://www.youtube.com/watch?v=TUoV2ue7amY.

check the fuses in the underhood fuse box?! could be more than one bad one.

Checking the 4X4 control module for DTC'S - diagnostic trouble codes is what you should done . Need a factory or professional type scan tool , no an OBD2 code reader . Looking at factory service repair info. description of how it works , an testing is how to diagnose . Not guessing an throwing parts at it . DTC B2725 The accessory switch circuit consists of 4 modes. The transfer case shift control module supplies 5 volts to the switch through the switch signal circuit. The current travels through the resistor of the currently active mode. The current on the switch signal circuit is monitored by the transfer case shift control module. The voltage on the switch signal circuit will vary depending on which mode button is pressed by the driver. The transfer case shift control module constantly monitors the switch signal circuit to determine the condition of the accessory switch circuit. When each of the modes are selected they complete a circuit through their own specific resistor. The transfer case shift control module continuously monitors the switch signal circuit to determine whether the Neutral, 2HI, 4HI, or 4LO mode was selected by the driver. DTC C0327 Encoder Circuit Malfunction The transfer case shift control module has 4 encoder circuits, and each circuit is supplied 12 volts. These 4 circuits are A, B, C, and P, and each circuit runs to a switch located inside the encoder/motor assembly. When a particular encoder circuit is active, the switch is closed, and the 12 volts are grounded by the switch inside the encoder. The transfer case shift control module supplies 12 volts on all the circuits. The module can interpret the location of the transfer case shift position when the circuits are grounded. This DTC detects a fault when it compares the shift sequence/strategy to a chart located in read only memory (ROM), within the electronic control unit (ECU), within the transfer case shift control module. This is accomplished by the module reading the different combinations of encoder signals being grounded while others remain high depending on what mode or range the transfer case is in. DTC C0550 ECU Malfunction At each power-up, the transfer case shift control module runs a self-test on the following functions: • EEPROM Checksum • ROM Checksum • RAM Checksum • RAM Malfunction I suggest your take your vehicle to a qualified repair shop .

Could be any number of thing's . Engine management system sensors . Anything mentioned on here would be a guess . Having a qualified repair shop with the proper testing equipment viewing sensor scan data is the way to a fix . Not going by peoples guess . It could be a fuel system or ignition system prblem , engine sensor etc.... 047 Engine Hard to Start or No Start Scan Data for Ignition 048 Engine Hard to Start or No Start Scan Data for Starting Problems Takes year's to learn how to properly diagnose these systems . I have over thrity year's experience , thousand's of dollars of scan tools , diagnostic equipment etc... An ever year they come of with new stuff , I go to GM tech school 4 or 5 times a year .

It will only crank to start in neutral or park. If you turned the switch off before you put in park, the shifter will not move up to get in either. Turn the switch on, put it in park, then turn the switch off. The key won't even come out if not in park. Safety features can sometimes be a pain, but they work.

obd II fuse located ???? Or do you mean fuse for DLC - the connector under the dash that you plug the scan tool into ? GIG LTR fuse 15 amp under hood fuse box

cold reader ?? CODE READER ! DTC P0449 Evaporative Emissions (EVAP) Vent Solenoid Control Circuit. Controlling Emissions How Evaporative Emission Control Systems Work

3rd sensor ?????? for what ? O2 ? What engine 3.5 L ?

Check transmition fluid

Put a code reader on it should tell you a code for powertrain

What size engine?

Selector solenoid in the tranny pan there should be two one for 1n2 and one for 3n4

Use a putty knife to scrape old gasket from the engine block and the pan. Put a punch that is larger in diameter that the bolt holes of the pan in a vise and use a hammer to flatten the pan around the bolt holes before installing the new gasket so it won't squeeze the new gasket when you tighten the pan bolts.

Have the u-joints checked for looseness or seizing. May also be an internal diff issue.

First you'll need to take it to have DTC's - diagnostic trouble codes check to find out what part of the system is at fault ! Could have a sensor , control module ,or wiring problem ! Traction Off Indicator The traction off indicator, which is a LED located on the traction control switch, illuminates only when the traction control switch has been pressed and released, disabling traction control. It is important to note that a traction fault does not illuminate this indicator and that there is no relationship between this indicator and the traction fault message. Traction Fault Message The IPC displays the traction fault message when either of the following instances occur. ?€¢ The EBCM detects a malfunction that requires traction control to be disabled. The EBCM sends a serial data message to the IPC requesting that the message be displayed.

?€¢ The IPC detects a loss of serial data communication with the EBCM

Traction Control System (TCS) When drive wheel slip is noted while the brake is not applied, the EBCM will enter traction control mode. The EBCM uses a 5-volt pulse-width modulated (PWM) signal to request the PCM to reduce the amount of torque to the drive wheels. The PCM reduces torque to the drive wheels by retarding spark timing and by commanding the throttle actuator control. The PCM uses a 5-volt PWM signal in order to report to the EBCM the amount of torque delivered to the drive wheels. You would need a factory grade scan tool to check data PID's - parameter identification , all the sensors work within a specific voltage range 1- 5 volts an you can see this on a good scan tool ! The Traction control is part of the ABS system an there a several DTC possible DTC B0827 DTC B0828 DTC B2745 DTC C0035 DTC C0035 or C0040 DTC C0040 DTC C0055 DTC C0110 DTC C0191 DTC C0201 DTC C0220-C0229 DTC C0240 or P0856 DTC C0244 or P1689 DTC C0245 DTC C0267 or C0268 and C067 or C068 DTC C0550 DTC C0899 DTC C0900 You best bet is to take it to a qualified repair shop !

It would seem to be a fuse or fusible link problem. Check the wiring diagram in the shop manual for the vehicle and check the fusible link that is common to headlight and fuel pump power supply and the other systems which are not working. If the fusible link checks okay check the main multipoint connector in the main wiring harness to the fuse block from the battery.

you have to reset the computer. 2 ways use your key to lock and unlock the door or use your remote to enter truck

hello, If the frt brakes are locked up then it could be any of the following, master cylinder is bad, frt brake lines are at fault the flexible rubber part that goes to the calipers, or the calipers themselves could be frozen and are not able to release when you let off the brake pedal.
