TPMS Troubleshooting Strategy

TPMS TROUBLESHOOTING STRATEGY
Use these steps to plan your diagnostic strategy. If you follow them thoroughly, you will be sure that you have exhausted most of the possible ways to find a TPMS fault.
1. Gather information about the problem from the customer.
2. Verify that the condition described by the customer exists. If the condition matches a symptom listed in the TPMS Symptom Chart, execute an inspection procedure for the symptom. TPMS Symptom Chart
3. Check the vehicle for any TPMS DTC.
4. If you cannot verify the condition and there are no TPMS DTCs, the malfunction is intermittent.

WHEN THE TPMS WARNING LIGHT IS ON
^ If the TPMS warning light illuminates, check the inflation pressure of all the tires and adjust if necessary. If the TPMS warning light still remains illuminated, a flat tire or a defective TPMS transmitter is suspected.
^ If a road tire does not contain a TPMS transmitter, the TPMS warning light will flash and the TPMS will not work normally. Replace the tire with one containing a TPMS transmitter.

AFTER REPLACING TPMS COMPONENTS
^ Whenever the TPMS transmitter and/or TPMS receiver are replaced, register the tire pressure sensor ID of all the TPMS transmitter-contained tires.
^ Whenever any TPMS component (transmitter and receiver) is removed and installed, confirm that no TPMS DTC is set.

5. If there is an TPMS DTC, record the number of the DTC, then erase the DTC from the memory using the scan tool.
6. Recreate the TPMS DTC set conditions to see if the same TPMS DTC will set again.
^ If the same TPMS DTC sets again, perform the TPMS diagnostic trouble code procedures for the DTC. Symptom Related Diagnostic Procedures
^ If you cannot get the same TPMS DTC to set again, the malfunction is intermittent.
