Can i disable traction control on gmc canyon
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.
My GMC Canyon won't start with neew battery, Next Day or week it will not start?
When battery voltage is lost, sometimes there are some modules that may need to be reprogrammed? It could effect your security system, where applicable. I don't know model year?
If it cranks good but won't start, make sure battery has a full charge. Have a helper crank it while you check for spark at the plugs. Also, check proper fuel pressure and fuel injector pulse. Find out what your missing, if anything?
Canyon 4wheeldrive light turned on
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 .
2005 gmc canyon computer not ready and not reading codes
If the check engine light was on DTC'S - diagnostic trouble code's should be stored . If the light was on , disconnecting the battery won't do anything . Diagnostic's need to be done . Sounds like you have no clue , so best advice , take it to a qualified repair shop .
Canyon starts but won't go into drive and no instruments
Have a scan tool hooked up , not a code read or what they use at the auto part stores . Need a factory tech2 or someother professional type that can check for DTC'S - diagnostic trouble codes in all the modules . Could be as simple as a loose ground connection , checking codes could point to the problem . Do you know what all the codes are ? P codes - engine & transmission ,B codes - body control module , C - chassie - ABS ,U codes - data communication network codes . This is something you should have a qualified repair shop check .
