NOTE:
After making any repairs, perform TIRE PRESSURE VERIFICATION TEST
under VERIFICATION TESTS.
Monitored & Set Condition
- When Monitored: Key ON.
- Set Condition: When the EVIC detects a no-transmit condition from the RF Sensor/Transmitter.
Possible Causes:
- EVIC Internal Fault
- Sensor/Transmitter Internal Fault
Testing
- Retrain the EVIC with the scan tool, record and erase DTC's. Drive the vehicle for 10 minutes at 20 MPH (32 KM/H). With the scan tool, read DTC's. If the scan tool displays a sensor failure or sensor low battery message, replace the indicated Tire Pressure Sensor/Transmitter. See TIRE PRESSURE MONITOR SYSTEMS - 300M article. If no, go to next step.
- Turn ignition on. Observe the EVIC display. If the EVIC displays SERVICE TIRE PRESS. SYSTEM, replace the EVIC. See TIRE PRESSURE MONITOR SYSTEMS - 300M article. If no, test is complete.
