2. Disconnect climate control unit connector A (28P).
3. Turn the ignition switch to ON (II).
4. Measure the voltage between climate control unit connector A (28P) terminal No. 9 and body ground.
CLIMATE CONTROL UNIT CONNECTOR A (28P)
* 1 : With navigation
*2: Without navigation
Is there battery voltage? YES
-Go to step 5.
NO

5. Turn the ignition switch to LOCK (0).
6. Check for continuity between .-climate control unit connector B (12P) terminal No. 3 and body ground.
CLIMATE CONTROL UNIT CONNECTOR B (12P)
Wire side of female terminals
Is there continuity? YES
-Check for loose wires or poor connections at climate control unit connector B (12P). If the connections are good, substitute a known-good climate control unit (with navigation) (see page 21-190), (without navigation) (see page 21-191), and recheck.
NO
-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 (see page 22-40).
