TPMS Indicator Does Not Go Off, and No DTCs Are Stored
TPMS indicator does not go off, and no DTCs are storedNOTE: Check for gauge DTCs with the HDS. If gauges DTCs are stored, troubleshoot these DTCs first.
1. Turn the ignition switch to LOCK (0).
2. Check the No. 1 (7.5 A) fuse in the under-dash fuse/relay box.
Is the fuse blown?
YES - Replace the No. 1 (7.5 A) fuse, and recheck.
NO - Reinstall the fuse, then go to step 3.
3. Check the No. 21 (7.5 A) fuse in the under-dash fuse/relay box.
Is the fuse blown?
YES - Replace the No. 21 (7.5 A) fuse, and recheck.
NO - Reinstall the fuse, then go to step 4.
4. Measure voltage between body ground and TPMS control unit 20P connector terminal No. 10.
Is there battery voltage?
YES - Go to step 5.
NO - Repair open in the wire between the TPMS control unit and the No. 1 (7.5 A) fuse in the under dash fuse/relay box.
5. Turn the ignition switch to ON (II).
6. Measure voltage between body ground and TPMS control unit 20P connector terminal No. 8.
Is there battery voltage?
YES - Go to step 7.
NO - Repair open in the wire between the TPMS control unit and the No. 21 (7.5 A) fuse in the under dash fuse/relay box.
7. Measure voltage between body ground and TPMS control unit 20P connector terminal No. 4.
Is there 0.1 V or more?
YES - Repair open or high resistance in the wire between the TPMS control unit and body ground (G401).
NO - Do the troubleshooting for the gauge control module. If the gauge control module is OK, check for loose terminals and poor connections at the TPMS control unit. If necessary, substitute a known-good TPMS control, and recheck.
