7. Turn the ignition switch ON (II).

8. Measure the voltage between the TPMS control

unit connector A (14P) terminal No. 5 and body
ground.

Repair the open in the ground wire between

terminal No. 3 at the TPMS control unit and body
ground.

Check fuse No. 21 (7.5 A) in the under-dash

fuse/relay box. If the fuse is OK, repair the open in
the wire between the under-dash fuse/relay box
and the TPMS control unit.

9. With the HDS, command the system to turn on

each tire indicator and the low pressure indicator.

Check for loose terminals and poor

connections at the TPMS control unit. If necessary,
substitute a known-good TPMS control unit and
recheck.

Do the input test for the gauge control module

(see page 22-122). If necessary, substitute a known-
good gauge control module and recheck.

1. Turn the ignition switch ON (II).

2. Command the system with the HDS to turn the

TPMS indicators off.

Check for loose terminals and poor

connections at the TPMS control unit. If necessary,
substitute a known-good TPMS control unit and
recheck.

Go to step 3.

3. Turn the ignition switch OFF, then disconnect the

gauge control module connector B (22P).

4. Turn the ignition switch ON (II), and watch the low

pressure and tire indicators.

Check for loose terminals and poor

connections at the TPMS control unit. If necessary,
substitute a known-good TPMS control unit and
recheck.

Do the input test for the gauge control module

(see page 22-122). If necessary, substitute a known-
good gauge control module and recheck.

(see page 22-122). If necessary, substitute a known-
good gauge control module and recheck.

5. Measure the voltage between the TPMS control

unit connector A (14P) terminal No. 5 and body
ground.

Go to step 6.

There is an open between the under-dash

fuse/relay box fuse No. 21 (7.5 A) and the TPMS
control unit. Check the No. 21 fuse (7.5 A). If the
