I have a 08 Canyon and was wondering if the low tire indiator light and bell can be turned off as it is a pain having it come on everyday. I have had it to the dealer and they have set the tire pressure and reset the computer. They tell me it cannot be turned off. I am tired of taking it back to the dealer for this and they do the same thing everytime.
The Keyless Entry (RKE) and Tire Pressure Monitoring (TPM) may go inoperative during vehicle low battery voltage conditions. IMPORTANT: Do not use this procedure/correction for every TPM issue. If 3 of the 5 symptoms described below are not present, STOP! There is no need to perform the below procedure/correction. First check the RCDLR software version. If the software version is CL or greater, there is no need to perform the below procedure/correction, STOP!
To find the software version for RCDLR:
1. Use latest version of Tech 2
2. Build the vehicle with Tech 2
3. Select Remote Control Door Lock Receiver
4. Select Module ID Information
5. Select Module Information
6. Look for parameter called Alpha Code -- software version displayed
Symptoms:
1. Both key fobs inoperative
2. Tire Pressure Monitoring (TPM) pressures show dashes
3. No TPM telltale illuminated
4. Possible DTCs are C0569, C0775, B3105 that set as current
5. NOTE: RKE module may not show up on Tech 2
Correction:
If this condition occurs, reflash the RCDLR then setup the module.
There are two utility files used to flash the module.
Utility File 1
Use the following Utility File 1 to reflash software to RCDLR when the following symptoms are displayed:
- Both key fobs inoperative
- Tire Pressure Monitoring (TPM) show dashes
- No TPM telltale illuminated
- Possible DTCs are C0569, C0775, B3105 that set as current
Utility File 1 -- CG Version = RCDLR Remote Control Door Lock Receiver (TSB 08-03-16-001A to correct field issues) Pass-Through Only
Utility File 2
Use the following Utility File 2 to reflash software to RCDLR when the following symptoms are displayed:
- Both key fobs inoperative
- Tire Pressure Monitoring (TPM) show dashes
- No TPM telltale illuminated
- Possible DTCs are C0569, C0775, B3105 that set as current
- RCDLR is not seen in Tech 2 menu
Utility File 2 -- CL Version = RCDLR Remote Control Door Lock Receiver (TSB 08-03-16-001A) with E4399 Error - Pass-Through Only
TIP: If a second reflash fails, replace the RCDLR module with a new module.
I would say it is either a programming issue with the RCDLR, or the body control module, as it may not allow the RCDLR to go into wake up mode and check the tires. There is a bulletin on this, and a recall from a couple years ago to reflash the BCM.
The other thing could be, the RCDLR may be bad, or on its way out. It could also be related to the antenna. I dont believe it is related to the tire pressure sensors. it is extremely rare to see all 4 of the tire sensors fail at the same time. It just doesnt happen and if the dashes go away after relearning tire positions, and the tire sensors respond then it probably isnt the sensors.
However if the dashes are there when you start it up and then they go away and the vehicle displays correct tire pressure data after say 15 or so minutes of consistant driving, then it is a problem with the sensors not waking up or the RCDLR not pinging the sensors to receive data from the sensors.
The sensors have an inertia switch internal to them that will put them into wake up mode as the car drives a set distance and a set speed, the car uses the last transmission of the tire pressure sensors before the car was turned off to display the tire pressure data that you see when you fire it up first thing in the morning, or on the next key cycle until it gets driven.
Either way it will need to go to the dealer to figure out if it is a internal battery issue to the sensors, or a RCDLR fault, or maybe a BCM issue. Note: Apparently if the BCM isn't programmed with the tire type and placard info, it does this exactly what your are going through. It will learn and show pressures after the learn, but any time the key is turned off it will "forget" the pressures and info.
Start with the updating any modules that needed it to the latest version of firmware that GM has for your Canyon, as well as programming in the tire type / placard info.
Good luck and keep us posted.
