Tire Pressure Monitoring

9150-TIRE PRESSURE SENSOR SIGNAL EXTERNAL INTERFERENCE

For a complete wiring diagram Consult Diagrams/Electrical

- When Monitored:
With the engine running. Vehicle speed greater than 10 mph (16 km/h).

- Set Condition:
The Tire Pressure Monitor (TPM) Module can not read the Tire Pressure sensors.





Diagnostic Test

1. DTC STATUS
NOTE: All communication faults must be diagnosed before continue.

Turn the ignition on.
Using the scan tool, read DTCs.
Is the DTC active?

Yes

- Go to 2

No

- The interference that caused the DTC to set is no long present. Test complete.

2. TPM SYSTEM

- Inspect and review the vehicle for the following:

- Review the vehicle repair history. The incorrect tire pressure sensor and/or transponder will set this DTC.
- Inspect for aftermarket rims that do not have Tire Pressure Sensor installed or that would not allow correct transmission of the sensor.
- Interference from other elements will over power the sensor/transmitter RF frequency making erratic operation to the TPM system. Check the vehicle for aftermarket accessories that could compromise the RF frequency signal before diagnosing the TPM system.

Were any of the conditions found?

Yes

- Repair as necessary.
- Perform TPM VERIFICATION TEST.

No

- Go to 3

3. TIRE PRESSURE SENSOR(S)
Using the TPM-RKE Analyzer, test each Tire Pressure Sensor.
Did all the Tire Pressure Sensors pass?

Yes

- Go to 4

No

- Replace the Tire Pressure sensor that fail. Test drive and retest.
- Perform TPM VERIFICATION TEST.

4. FRONT TIRE PRESSURE TRANSPONDER
Turn the ignition on.
Using the scan tool, perform the Tire Pressure Signal Transmission Test on the Front Tire Pressure Sensors.
Was the signal transmission test successful for both sensors?

Yes

- Go to 5

No

- Replace the Front Tire Pressure Transponder.
- Perform TPM VERIFICATION TEST.

5. REAR TIRE PRESSURE TRANSPONDER
Turn the ignition on.
Using the scan tool, perform the Tire Pressure Signal Transmission Test on the rear tire pressure sensors.
Was the signal transmission test successful for both sensors?

Yes

- Replace the TPM Module.
- Perform TPM VERIFICATION TEST.

No

- Replace the Rear Tire Pressure Transponder.
- Perform TPM VERIFICATION TEST.
