Diagnostic Procedure

PRNDL MESSAGE MISSING SYMPTOM CHART

TEST ACTION APPLICABILITY
1
NOTE: If the TPM indicator is illuminated, check for a low tire pressure condition. If the TPM indicator is flashing, check for DTC's.
NOTE: The below test is to locate the Tire Pressure Sensor/Transmitter.
NOTE: If the tires have been rotated, the Tire Pressure Sensor/Transmitters are no longer in sequence from the factory. Faults are linked to Sensor/Transmitter ID's.
NOTE: You must determine which Tire Pressure Sensor/Transmitter has set the fault or alert before diagnosing the system correctly.
NOTE: Set ALL tire pressures to recommended specifications and recheck for faults/alerts.
The fault will set within two minutes when at 20 PSI.Starting with the left front wheel, deflate the tire down to 20 PSI and wait 2 minutes.If the TPMS fault was detected and associated to this Sensor/Transmitter, it would correspond to the left front Sensor/Transmitter.If the TPMS fault was detected and not associated to this Sensor/Transmitter, repeat the process until the faulty Sensor/Transmitter has been identified.
NOTE: Once a fault/alert has set, it will establish the location of the Tire Pressure Sensors/Transmitter. Repeat steps until the applicable Tire Pressure Sensor/Transmitter has been located.
