1. Check the No. 3 (7.5A) fuse in the driver’s under-

dash fuse/relay box, and the No. 13 (7.5A) fuse in
the passenger’s under-dash fuse/relay box.

• Without Navigation System: Go to step 2.
• With Navigation System: Go to step 8.

Replace the fuse(s), and recheck.

2. Disconnect climate control unit connector A (8P).

3. Turn the ignition switch ON (II).

4. Measure the voltage between the No. 1 terminal of

climate control unit connector A (8P) and body
ground.

Go to step 5.

Repair open in the wire between the No. 3

fuse in the driver’s under-dash fuse/relay box and
the climate control unit.

5. Turn the ignition switch OFF.

6. Measure the voltage between the No. 2 terminal of

climate control unit connector A (8P) and body
ground.

Go to step 7.

Repair open in the wire between the No. 13

fuse in the passenger’s under-dash fuse/relay box
and the climate control unit.

7. Check for continuity between the No. 8 terminal of

climate control unit connector A (8P) and body
ground.

Check for loose wires or poor connections at

climate control unit connector A (8P). If the
connections are good, substitute a known-good
climate control unit, and recheck. If the symptom/
indication goes away, replace the original climate
control unit.

Check for an open in the wire between the

climate control unit and body ground. If the wire is
OK, check for poor ground at G401.

8. Disconnect climate control unit connector B (26P).

9. Turn the ignition switch ON (II).

10. Measure the voltage between the No. 13 terminal

of climate control unit connector B (26P) and body
ground.

Go to step 11.

Repair open in the wire between the No. 3

fuse in the driver’s under-dash fuse/relay box and
the climate control unit.

11. Turn the ignition switch OFF.

12. Check for continuity between the No. 15 terminal of

climate control unit connector B (26P) and body
ground.

Check for loose wires or poor connections at

climate control unit connector B (26P). If the
connections are good, substitute a known-good
climate control unit, and recheck. If the symptom/
indication goes away, replace the original climate
control unit.

Check for an open in the wire between the

climate control unit and body ground. If the wire is
OK, check for poor ground at G401.
