- With the scan tool, select instrument panel special functions Lamp Test. Command the instrument panel lamps ON. Verify low tire pressure indicator lamp turns ON.
- If the lamp does not turn ON, replace the IPC.
- Using the tire pressure monitor (TPM) special tool to observe the tire pressure of the suspected faulty sensor. Check air pressure with a known accurate hand held tire pressure gage. Compare the psi reading to the display on the TPM special tool. Verify pressure readings from special tool do not differ 2 psi or more than actual tire pressure.
- If the difference is 2 psi more, replace the suspect tire pressure sensor.
- With the scan tool, observe tire pressures in the scan tool data display. Verify pressure readings from special tool do not differ 2 psi or more than scan tool data display.
- If the difference is 2 psi more, replace the RCDLR.
