Pinpoint Test
- CHECK THE SENSOR IDENTIFIERS AND SYSTEM STATUS Parameter Identifications (PIDs)
- Connect the scan tool.
- Ignition ON.
- Using a scan tool, view Body Control Module (BCM) Parameter Identifications (PIDs):
- Left Front Tire Transmitter Identifier (TPM_S_ID_LF)
- Right Front Tire Transmitter Identifier (TPM_S_ID_RF)
- Left Rear Tire Transmitter Identifier (TPM_S_ID_LRO)
- Right Rear Tire Transmitter Identifier (TPM_S_ID_RRO)
- Monitor the Tire Pressure Monitoring System (TPMS) Parameter Identification (PID) TPMS_STATUS.
- Does the TPMS_STATUS Parameter Identification (PID) display SENSOR FAULT?
- Yes: GO to step 2 .
- No: If the TPMS_STATUS Parameter Identification (PID) displays SYSTEM FAULT, REFER to DIAGNOSTIC ROUTINE A .
- CARRY OUT THE SENSOR TRAINING PROCEDURE (SENSOR FAULT)
- Train all 4 Tire Pressure Monitoring System (TPMS) sensors. REFER to TIRE PRESSURE MONITORING SYSTEM (TPMS) SENSOR TRAINING - INTELLIGENT ACCESS (IA) or REFER to TIRE PRESSURE MONITORING SYSTEM (TPMS) SENSOR TRAINING - INTEGRATED KEYHEAD TRANSMITTER (IKT) .
- Did all of the tire pressure sensors transmit correctly and did the horn sound when each Tire Pressure Monitoring System (TPMS) sensor transmitted to the Body Control Module (BCM)?
- Yes:
Using the scan tool, LOCATE the updated Tire Pressure Monitoring System (TPMS) sensor identifiers trained to the Body Control Module (BCM).
COMPARE these values to those recorded prior to the Tire Pressure Monitoring System (TPMS) sensor training procedure. Disregarding sensor position, any sensor identifiers that do not match those retrieved from the module were changed, but not retrained. The sensors are now trained to the vehicle, diagnosis is complete.
DOCUMENT all Tire Pressure Monitoring System (TPMS) sensor identifiers on the applicable warranty claim.
- No:
Before installing a new sensor(s): If a sensor does not respond to the Tire Pressure Monitor (TPM) Activation Tool, MOVE the vehicle to rotate the wheels at least one-fourth of a turn and ATTEMPT to activate the same sensor again. If the sensor still fails to train, ATTEMPT to train the sensor with the vehicle doors open.
If the sensor(s) fails to train a second time, INSTALL a new Tire Pressure Monitoring System (TPMS) sensor(s) for the sensor(s) in question. REFER to TIRE PRESSURE MONITORING SYSTEM (TPMS) SENSOR .
