General Troubleshooting Information

How to Troubleshoot DTCs ('07 Model)
DTC troubleshooting procedures assume the cause of the problem is still present and the TPMS indicator is still on. (NOTE: the TPMS indicator comes on for DTCs 11, 13, 15, and 17 only if the low tire pressure indication is false, caused by a problem in the system.) Do not use a troubleshooting procedure unless the system has set the DTC listed for it.

1. Ask the client to describe the conditions when the indicator came on, and try to reproduce the same conditions for troubleshooting. Find out if the client checked and/or adjusted tire pressures since the indicator came on.
2. If an indicator does not come on during the test drive, check for loose terminals, poor contact due to damaged terminals, etc. before you start troubleshooting.
3. After troubleshooting, clear the DTCs, and test drive the vehicle. Make sure no indicators come on.
4. Check for other unit DTCs which are connected via F-CAN. If there are DTCs then are related to F-CAN, the most likely cause was then the ignition switch was turned to ON (II) with the TPMS control unit connector disconnected. Clear the DTCs. Check for PGM-FI and TPMS codes, and troubleshoot these first.
