clearing trouble code

[johnnyg123]

i just had a shop install a new gm radio in my new ride. it has the cd and mp player versus just the am/fm. after driver a few miles a message showed up to check my tire monitoring system which i dont have since its a work truck model. i had a feeling it might happen.is there any way to clear it and message without going to the dealer thanks

Disconnect the ground on the battery wait a few beers and reconnect.

Worth a try.... or bring to a shop if doesn't work

Anymore most small repair shops/oil change lube shop usually have an OBDII tool to clear codes.

They installed a NEW GM unit?

Note that 2003 and up GM/delco/delpi radios are VIN locked.

If you/they installed a used unit from a 2003 and up it wouldn't work and would need to be

unlocked by a GM dealer Tech2 machine.

 

Is it a aftermarket unit?

 

Did they modify the stock wiring?

 

If its a fault with the TPMS most garage scanners won't clear TPMS codes or lights.

Ask me how I know........................

my bad.i dont think its coming from radio. the night before installed a set of tires and wheels that were take offs. they are the gmc 18 polished aluminum wheels. when i bought them i was asked if i needed the tps sensors. told them no. didnt think i had the tpms on the truck since it was the wt model. last truck was 03 wt and didnt have them. then i read my window sticker and the truck has them. so now the tires have to come back off and have them installed. im going to use the other set for the winter so ill leave the sensors in the steel wheels i just took off. .tomorrows project after work . almost done getting it where i want it

YUP............The FEDS require TPMS in all 07 and up pass. cars and trucks IIRC.

(thank Explorer/Firestone owners for that BTW)

 

The older 2 piece TPMS sensors from GM are $75 bucks each.

The newer models are 1 piece. No idea how much they cost.

 

Pretty sure your tire dealer may have aftermarket sensors.

Check around before you buy sensors from the GM dealer

 

Look here: OUCH!

TPMS reset can be done without a tool. This works on my 2011 GMC 2500HD. I think it works on most up to 2012(think they changed that year). Earlier models used the light switch instead of the lock buttons on the key fob. Switch the lights back and forth from Auto to Parking Light 4 times in 4 seconds to activate.

 

 

CLEAR TIRE PRESSURE MONITOR ERROR ON DIC (DRIVER INFORMATION CENTER)

 

The tire pressure monitor (TPMS) system uses the passenger door module (PDM), the body control module (BCM), the remote key fob, the 4 radio frequency transmitting pressure sensors in the tire valves, and the serial data circuit to perform the sensor learn mode functions.

 

LEARN MODE DESCRIPTION

 

In order to read correctly, the sensors relearn procedure must be performed any time the PDM is replaced, a tire sensor is replaced, or after the vehicle's tires have been rotated. Once the relearn mode has been enabled, each of the sensors' unique identification code can be programmed ("learned") into the PDM's memory. When a sensor's ID code has been learned, the PDM sends a serial data message to the BCM to sound a horn chirp. This verifies the sensor has transmitted it’s ID code and the PDM has received it. As soon as the first sensor ID code is learned, all other IDs are erased from the PDM's memory.

 

LEARN MODE CANCELLATION

The TPM system will cancel the learn mode if more than 2 minutes have passed and no sensors have been learned, or if the system has been in learn mode for more than 5 minutes. If the learn mode is canceled before any sensor has been learned, the PDM will remember all current sensor IDs and their locations.

 

STEP BY STEP:

 

1. Turn "ON" the ignition, with the engine OFF.

2. Hold down the Lock and Unlock on the remote key fob until the horn chirps twice and the Low Tire Relearn message shows on the DIC.

 

CAUTION: Over inflating tires may cause personal injury or damage to the tires and wheels. When increasing tire pressure do not exceed the maximum inflation pressure as noted on the tire sidewall.

 

IMPORTANT: If a horn chirp does not sound after 35 seconds for any of the 4 sensors, turn the ignition "OFF" to exit the learn mode and repeat the procedure from step 1.

 

4. Starting with the Left Front tire, increase or decrease the pressure for 8-10 seconds or until the horn chirps once. The horn chirp may occur before the 8-10 second pressure increase/decrease time period has been reached, or up to 30 seconds after the 8-10 second pressure increase/decrease time period has been reached.

 

 

5. After the horn chirps, proceed as in step 4 for the next 3 sensors in the following order:

B-- Right front C-- Right rear C-- Left rear

 

6. After all sensors have been “learned”, the horn will chirp 2 times. Then exit the learn mode by turning "OFF" the ignition.

 

 

7. After the learn mode has been exited, adjust all tire pressures to the recommended psi.

 

 

8. Check the dash DIC to see that the correct tire pressure is listed.

 

Take note: If you do a wheel rotation, they may still work fine. The only problem is that they won't read the correct tire. Let's say you did a same side tire rotation, front to back. Now let's say you get a nail in the driver side front tire, and the air leaks out. On your display, it will show that your driver side REAR tire is low on pressure. So best to do a TPMS reset. FYI – the Low Tire Warning will go on/off at 5psi under recommended on door jam.
