DIC Relearn Enable Method
NOTE:
If using the DIC buttons to enable the relearn mode, the TPM tool or Pressure Increase/Decrease Method may be used. Before proceeding with this method, ensure that no other learn procedure is being performed simultaneously or that tire pressures are not being adjusted on another TPM equipped vehicle within close proximity. Stray signals from other TPM equipped vehicles just driving by can be inadvertently learned. If audible signals are heard at random from the car while learning is taking place, a foreign sensor has probably been learned and the procedure needs to be disabled and repeated. In this case, it is best to execute the TPM relearning procedure at a distance from other cars. In the event a particular sensor activation does not cause the horn to chirp, it may be necessary to rotate the wheel valve stem to a different position due to the sensor signal is being blocked by another component
- Turn ignition ON.
- Activate the learn mode with the driver information center (DIC) display controls. Go to "Vehicle Information Menu" > "Tire Pressure Menu ". A double horn chirp sounds indicating the learn mode has been enabled and the left front turn signal will also be illuminated.
- Starting with the left front tire, activate the tire pressure sensor by using one of the following methods:
- Starting with the Left Front tire, active the sensor by holding the antenna of the TPM tool aimed upward against the tire sidewall close to the wheel rim at the valve stem location. Press and release the Activate button and wait for a horn chirp. Once the horn chirp has sounded, the sensor information is learned and the turn signal in the next location to be learned will illuminate.
- Increase/decrease the tire pressure for 8-10 seconds then wait for a horn chirp. The horn chirp may occur before or up to 30 seconds after the 8-10 second pressure increase/decrease time period has been reached. Once the horn chirp has sounded, the sensor information is learned and the turn signal in the next location to be learned will illuminate.
- After the horn chirp has sounded and the right front turn signal is illuminated, repeat procedure for the remaining 3 sensors in the following order: Right Front, Right Rear, Left Rear.
- When the left rear sensor has been learned and a double horn chirp has sounded, the learn process is complete and the BCM exits the Relearn mode.
- Turn ignition OFF. Adjust all tires to the recommended pressures.
