TPMS Indicator Does Not Go Off, and No DTCs Are Stored

WARNING: This page is about a different car, the 2013 Honda Fit, 2012 Honda Fit, 2011 Honda Fit, 2010 Honda Fit, and 2009 Honda Fit. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If the TPMS control unit was replaced, the TPMS indicator will be on until all four tire pressure sensor ID codes are learned.

Turn the ignition switch to ON (II).
Check the TPMS indicator for several seconds when the ignition switch is turned to ON (II).
Did the indicator come on and then go off?

YES - Intermittent failure, the system is OK at this time.

NO - Go to step 3.
Turn the ignition switch to LOCK (0).
Check the No. 2 (7.5 A) fuse in the under-dash fuse/relay box.
Is the fuse blown?

YES - Replace the fuse. Turn the ignition switch to ON (II), then turn it to LOCK (0) again. If the fuse blows again, repair the short to ground on the No. 2 (7.5 A) fuse circuit.

NO - Reinstall the fuse, then go to step 5.
Check the No. 22 (7.5 A) fuse in the under-dash fuse/relay box.
Is the fuse blown?

YES - Replace the fuse. Turn the ignition switch to ON (II), then turn it to LOCK (0) again. If the fuse blows again, repair the short to ground on the No. 22 (7.5 A) fuse circuit.

NO - Reinstall the fuse, then go to step 6.
Do the gauge control module self-diagnostic function (see SELF-DIAGNOSTIC FUNCTION ).
Is the gauge control module OK?

YES - Go to step 7

NO - Replace the gauge control module (see GAUGE CONTROL MODULE REPLACEMENT ).
Disconnect the TPMS control unit 20P connector (see TPMS CONTROL UNIT REPLACEMENT ).
Measure the voltage between body ground and TPMS control unit 20P connector terminal No. 10.
Is there battery voltage?

YES - Go to step 9.

NO - Repair open in the wire between the TPMS control unit and the No. 2 (7.5 A) fuse in the under-dash fuse/relay box.

Turn the ignition switch to ON (II).
Measure the voltage between body ground and TPMS control unit 20P connector terminal No. 8.
Is there battery voltage?

YES - Go to step 11.

NO - Repair open in the wire between the TPMS control unit and the No. 22 (7.5 A) fuse in the under-dash fuse/relay box.

Turn the ignition switch to LOCK (0).
Reconnect the TPMS control unit 20P connector.
Turn the ignition switch to ON (II).
Measure the voltage between body ground and TPMS control unit 20P connector terminal No. 3.
Is there 0.2 V or more?

YES - Repair open or high resistance in the wire between the TPMS control unit and body ground (G502).

NO - Go to step 15

Turn the ignition switch to LOCK (0).
Disconnect gauge control module 32P connector (see GAUGE CONTROL MODULE REPLACEMENT ).
Disconnect the TPMS control unit 20P connector (see TPMS CONTROL UNIT REPLACEMENT ).

Check for continuity between TPMS control unit 20P connector terminals and gauge control module 32P connector terminals (see table below).

Is there continuity?

YES - 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 TPIV S control unit (see TPMS CONTROL UNIT REPLACEMENT ), and recheck.

NO - Repair an open in the wire between the TPMS control unit and the gauge control module.
