TPMS indicator does not go off, and no DTCs are stored
- Check for gauge DTCs with the HDS (see WIRE COLOR CODES ) If the multiple DTCs are present, including B1178, troubleshoot those DTCs first If only DTC B1178 is present, continue with the following troubleshooting
- If the TPMS control unit was replaced, the TPMS indicator will be on until all four sensor ID codes are learned
- Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode
- Check the No 29 (7.5 A) fuse in the driver's under-dash fuse/relay box
Is the fuse blown?
YES -Go to step 3
NO -Reinstall the checked fuse, then go to step 8
- Disconnect the TPMS control unit 20P connector
- With the No 29 (7.5 A) fuse removed, check for continuity between body ground and the TPMS control unit 20P connector terminal No 10

Is there continuity?
YES -Repair short to body ground in the wire between the No 29 (7.5 A) fuse in the driver's under-dash fuse/relay box and the TPMS control unit
NO -Install a new No 29 (7.5 A) fuse in the driver's under-dash fuse/relay box, then go to step 5.
- Reconnect the TPMS control unit 20P connector
- Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
- Check the TPMS indicator when the ignition switch to ON (II), or the engine start/stop button is pressed to select the ON mode.
Did the idicator Come on?
YES -Check for loose terminals and poor connections at the TPMS control unit If necessary, substitute a known-good TPMS control unit (see TPMS CONTROL UNIT REPLACEMENT ), and recheck.
NO -Troubleshooting is complete.
- Check the No 12 (7.5 A) fuse in the driver's under-dash fuse/relay box
Is the fuse blown?
YES -Replace the fuse. Turn the ignition switch to ON (II) and then back to LOCK (0), or press the engine start/stop button to select the ON mode and then the OFF mode. If the fuse blows again, repair the short to ground on the No. 12 (7.5 A) fuse circuit
NO -Reinstall the checked fuse, then go to step 9.
- Disconnect the TPMS control unit 20P connector
- Measure the voltage between body ground and TPMS control unit 20P connector terminal No 10

Is there battery voltage?
YES -Go to step 11
NO -Repair open in the wire between the TPMS control unit and the No 29 (7.5 A) fuse in the driver's under-dash fuse/relay box
- Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode
- Measure the voltage between body ground and TPMS control unit 20P connector terminal No 8

Is there battery voltage?
YES -Go to step 13
NO -Repair open in the wire between the TPMS control unit and the No 12 (7.5 A) fuse in the driver's under-dash fuse/relay box
- Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.
- Reconnect the TPMS control unit 20P connector.
- Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the ON mode.
- Measure the voltage between body ground and TPMS control unit 20P connector terminal No. 3.
Is there 0.1 V or more?
YES -Repair an open or high resistance in the wire between the TPMS control unit and body ground (G403).
NO -Do the troubleshooting for the gauge control module (see SELF-DIAGNOSTIC FUNCTION ). 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 (see TPMS CONTROL UNIT REPLACEMENT ), and recheck
