Tire Monitoring System: Service and Repair
TRAINING THE EVICThe EVIC can be trained to recognize the source locations of Sensor/Transmitter signals. The training procedure is given below:
1. From the Programmable Features List select "RETRAIN TIRE SENSORS YIN" using the EVIC MENU button.
Use the STEP button to select and the MENU button to confirm "YES". The EVIC will initiate the following procedure.
2. A display will prompt the user to: "TRAIN DRIVER FRONT SENSOR". At this point the user must set the left front tire Sensor/ Transmitter to learn mode by positioning a magnet (Relearn Magnet special tool 8821) over the valve stem for at least 5 seconds. The Sensor/ Transmitter in the front left tire will transmit a message indicating to the EVIC that it is in learn mode. When the EVIC has received this message and is assured that it has learned an ID, the EVIC will request a horn chirp via a bus message and then display the next train request.
Note: The EVIC will allow 60 seconds from the first train request display to the receipt of a unique learn ID message from the first Sensor/Transmitter and 30 seconds for each succeeding wheel. If either of these timers expires, the EVIC will abort the training procedure and revert to previous settings. The EVIC will not store one ID for multiple locations.
3. The EVIC will request the initiation of a training sequence for each tire, one-by-one in a clockwise direction around the vehicle (Left Front, Right Front, Right Rear and Left Rear).
NOTE:
1. If one or all Sensor/Transmitters cannot be trained, move vehicle to avoid radio frequency interference.
2. If one Sensor/Transmitter still cannot be trained, replace it and retry.
3. If all Sensor/Transmitters still fail to train, replace the EVIC.
4. Once all tires are successfully learned, the previous set of stored IDs will be replaced by the new IDs, and the EVIC will display, "TRAINING COMPLETE" until a button is pressed.
If the vehicle is equipped with the Homelink feature and a Homelink button is pressed at any time during the training procedure, the EVIC module will immediately exit the training procedure, discard any IDs learned in the current session and perform the Homelink function. After the button is released, the module will display "RETRAIN TIRE SENSORS? NO."
The training procedure can be stopped at any time by pressing the C/T, STEP, RESET or MENU button. When any of these buttons are pressed the EVIC will display "TRAINING ABORTED" until another button is pressed and then display "RETRAIN TIRE SENSORS? NO."
Sensor/transmitter replacement or tire rotation will require retraining of the EVIC.
