INSPECTION
1. INSPECT ILLUMINATION OPERATION
Connect the positive (+) lead from the battery to terminal A −13
and the negative ( −) lead to terminal A−3, then check that the
illuminations light up.
If illuminations do not light up, test the bulb.
2. Air Inlet Control Switch:
INSPECT INDICATOR LIGHT OPERATION
(a) Connect the positive (+) lead from the battery to terminal
A−9 and the negative ( −) lead to terminal A−8.
(b) With the air inlet control button pushed in, check that the FRESH or RECIRC indicator light lights up.
(c) Next, push in the button again, and check that the indica-
tor light goes off and the other indicator light lights up.

If continuity is not as specified, replace the A/C control assem-
bly.
9. INSPECT A/C OR DEF SWITCH CONTINUITY
Check that there is continuity between terminals B− 6 and B−17
intermittently each time the A/C or DEF switch button pressed.
If continuity is not as specified, replace the A/C control assem-
bly.
10. INSPECT TEMPERATURE CONTROL SWITCH RESIS-
TANCE
(a) Measure resistance between terminals B −1 and B−2.
Standard resistance:
Approx. 3.0 kΩ
(b) Check that the resistance between terminals B −1 and
B−3 increases from 0 to approx. 3.0 k Ω when the switch
knob is turned from COOL to HOT.
If operation is not as specified, replace the A/C control assem-
bly.

INSPECTION
1. INSPECT SHIFT LOCK CONTROL ECU
Using a voltmeter, measure the voltage at each terminal.
HINT:
Do not disconnect the ECU connector.
2. INSPECT SHIFT LOCK SOLENOID
(a) Disconnect the solenoid connector.
(b) Using an ohmmeter, measure the resistance between ter-
minals.
Standard resistance: 20 − 28 Ω
If the resistance is not as specified, replace the solenoid.
(c) Apply the battery positive voltage between terminals. At this time, confirm that solenoid operate.
If the operation is not as specified, replace the solenoid.
