TPMS Indicator and Message Center Messages

TPMS Indicator and Message Center Messages
The TPMS indicator and vehicle message center (if equipped) sometimes displays faults that cannot be resolved by the customer. Treat these messages as TPMS faults that must be serviced.

TPMS Indicator Illuminates Continuously

NOTE: If the spare tire is in use, the damaged road tire must be repaired and installed on the vehicle to restore complete TPMS functionality before carrying out any diagnosis.

1. The TPMS indicator remains on continuously for this condition:
^ Low Tire Pressure - The TPMS indicator is illuminated solid and the message center displays LOW TIRE PRESSURE (if equipped). This is displayed when any of the tire pressures are low. When this condition exists, the tire pressure must be adjusted to the recommended cold pressure as indicated on the vehicle certification label.

2. NOTE: The TPMS sensors do not transmit when the vehicle is stationary. If the vehicle has been stationary for more than 30 minutes, it will be necessary to wake up the sensors so they will transmit the latest tire pressure information to the SJB.

If the vehicle has been stationary for more than 30 minutes carry out this procedure to "wake up" the TPMS sensors.
1 Turn the ignition switch to the ON position.
2 Adjust the air pressure in the LF tire.
3 Activate the LF TPMS sensor at least 2 times, using the tire pressure monitor activation tool.
4 Repeat Steps 2 and 3 for the remaining tires.
5 If the TPMS indicator remains illuminated after adjusting and activating each sensor, GO to Symptom Chart. Symptom Related Diagnostic Procedures

TPMS Indicator Flashes
The TPMS indicator flashes for 70 seconds and then remains ON solid when the ignition key is turned to the ON position for these conditions:
1. Tire Pressure Sensor Fault - If equipped, the message center will display TPMS SENSOR FAULT when a tire pressure sensor is malfunctioning. GO to Symptom Chart. Symptom Related Diagnostic Procedures
2. No communication with the SJB (TPMS is integral to the SJB) - The TPMS indicator is illuminated when the instrument cluster has received no signals from the SJB for more than 5 seconds. If equipped, the message center displays TPMS MONITOR FAULT. GO to Symptom Chart. Symptom Related Diagnostic Procedures
3. Tire Pressure Monitor Fault - If equipped, the message center will display TPMS MONITOR FAULT when the tire pressure monitoring system is malfunctioning or communication with the instrument cluster is lost. GO to Symptom Chart. Symptom Related Diagnostic Procedures
