8. Disconnect the TPMS control unit 20P connector.
9. Measure the voltage between TPMS control unit
20P connector terminals No. 3 and No. 8.
Repair short to power in the wire between
the TPMS control unit and the No. 10 (7.5 A) fuse in
the under-dash fuse/relay box.
Check for loose terminals and poor
connections at the TPMS control unit. If necessary,
substitute a known-good TPMS control unit
(see page 18-75), and recheck. 1. Turn the ignition switch to LOCK (0).
2. Disconnect the TPMS control unit 20P connector.
3. Turn the ignition switch to ON (II).
4. Check the low tire pressure indicator for several
seconds when the ignition switch is turned ON (II).
Check for loose terminals and poor
connections at the TPMS control unit. If necessary,
substitute a known-good TPMS control unit
(see page 18-75), and recheck.
Do the troubleshooting for the gauge control
module (see page 22- 241). If necessary, substitute a
known-good gauge control module (tach) (see page
22-277), and recheck.

1. Turn the ignition switch to LOCK (0).
2. Disconnect the TPMS control unit 20P connector.
3. Turn the ignition switch to ON (II).
4. Check the TPMS indicator for several sec
onds
when the ignition switch is turned ON (II).
Check for loose terminals and poor
connections at the TPMS control unit. If necessary,
substitute a known-good TPMS control unit
(see page 18-75), and recheck.
Do the troubleshooting for the gauge control
module (see page 22- 241). If necessary, substitute a
known-good gauge control module (tach) (see page
22-277), and recheck. NOTE: Check for gauge DTCs with the HDS (see page
22-6). If gauge DTCs are stored, troubleshoot those
DTCs first.
1. Turn the ignition switch to ON (II).
2. Check the TPMS indicator for several sec onds
when the ignition switch is turned ON (II).
The system is OK at this time.
Go to step 3.
3. Turn the ignition switch to LOCK (0).
4. Check the No. 7 (7.5 A) fuse in the under-dash fuse/ relay box.
Replace the No. 7 (7.5 A) fuse, and recheck. If
the fuse blows again, check for a short to body
ground in the wire between the TPMS control unit
and the No. 7 (7.5 A) fuse in the under-dash fuse/
relay box.
Reinstall the checked fuse, then go to step 5.
5. Check the No. 10 (7.5 A) fuse in the under-dash fuse/relay box.
Replace the No. 10 (7.5 A) fuse, and recheck.
If the fuse blows again, check for a short to body
ground in the wire between the TPMS control unit
and the No. 10 (7.5 A) fuse in the under-dash fuse/
relay box.
Reinstall the checked fuse, then go to step 6.
6. Disconnect the TPMS control unit 20P connector.

7. Measure the voltage between body ground and TPMS control unit 20P connector terminal No. 10.
Go to step 8.
Repair open in the wire between the TPMS
control unit and the No. 7 (7.5 A) fuse in the under-
dash fuse/relay box.
8. Turn the ignition switch to ON (II).
9. Measure the voltage between body ground and TPMS control unit 20P connector terminal No. 8.
Go to step 10.
Repair open in the wire between the TPMS
control unit and the No. 10 (7.5 A) fuse in the under-
dash fuse/relay box. 10. Turn the ignition switch to LOCK (0).
11. Reconnect the TPMS control unit 20P connector.
12. Turn the ignition switch to ON (II).
13. Measure the voltage between body ground and
TPMS control unit 20P connector terminal No. 3.
Repair open or high resistance in the wire
between the TPMS control unit and body ground
(G504).
Do the troubleshooting for the gauge control
module (see page 22-241). If the gauge control
module (tach) is OK, check for loose terminals and
poor connections at the TPMS control unit. If
necessary, substitute a known-good TPMS control
unit (see page 18-75), and recheck.
