(a) Connect the positive (+) lead from the battery to terminal
2 and the negative ( −) lead to terminal 4, and check that
the door lock link moves to UNLOCK position.
(b) Remove the polarity, and check that the door lock link move to LOCK position.
If operation is not as specified, replace the door lock assembly.
6. Using an ammeter: INSPECT PTC THERMISTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal 2.
(b) Connect the positive (+) lead from the ammeter to termi- nal 4 and the negative ( −) lead to battery negative ( −) ter-
minal, and check that the current changes from approxi-
mately 3.2 A to less than 0.5 A within 20 to 70 seconds.
(c) Disconnect the leads from terminals.
(d) After approximately 60 seconds, connect the positive (+) lead from the battery to terminal 4 and the negative ( −)
lead to terminal 2, and check that the door lock moves to
LOCK position.
If operation is not as specified, replace the door lock assembly.
7. Using an ammeter with a current−measuring probe: INSPECT PTC THERMISTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal 2 and the negative ( −) lead to terminal 4.
(b) Attach a current−measuring probe to either the positive (+) lead or the negative ( −) lead, and check that the cur-
rent changes from approximately 3.2 A to less than 0.5 A
within 20 to 70 seconds.
(c) Disconnect the leads from terminals.
(d) After approximately 60 seconds, reverse the polarity, and
check that the door lock moves to LOCK position.
If operation is not as specified, replace the door lock assembly.

If circuit is as specified, inspect the door lock signal.
If the circuit is not as specified, inspect the circuits connected
to other parts.
11. INSPECT DOOR LOCK SIGNAL
HINT:
When the relay circuit is as specified, inspect the door lock sig-
nal.
(a) Connect the connector to the relay.
(b) Connect the positive (+) lead from the voltmeter to termi-
nal 3 and the negative ( −) lead to terminal 4.
(c) Set the door lock manual switch to UNLOCK, and check
that the voltage rises from 0 V to battery positive voltage
for approximately 0.2 seconds.
(d) Reverse the polarity of the voltmeter leads.
(e) Set the door lock manual switch to LOCK, and check that the voltage rises from 0 V to battery positive voltage for
approximately 0.2 seconds.
If operation is not as specified, replace the relay.

12. NSPECT KEY−OFF POWER WINDOW SIGNAL
HINT:
When the relay circuit is as specified, inspect the key −off power
window signal.
(a) Connect the connector to the relay.
(b) Connect the positive (+) lead from the voltmeter to termi- nal 15 and the negative ( −) lead to terminal 16.
(c) Close the door with ignition switch truned to LOCK or ACC, check that the meter needle indicates battery posi-
tive voltage.
(d) Open the door, check that the meter needle indicates 0 V.
(e) Turn the ignition switch ON, check that the meter needle
indicate battery positive voltage again.
If operation is not as specified, replace the relay.

4. INSPECT SLIDING ROOF MOT OR CIRCUIT BREAKER
OPERATION
(a) With the sliding roof in the fully opened position, hold the
sliding roof switch in ”OPEN” position and check that
there is a circuit breaker operation noise within 4 to 40 se-
conds.
(b) With the sliding roof in fully opened position, hold the slid-
ing roof switch in ”CLOSE” position and check that the
sliding roof begins to close within 60 seconds.
If operation is not as specified, replace the motor.
5. INSPECT SLIDING ROOF MOTOR WIRE CIRCUIT
(a) Check that there is continuity between terminals A2 and B2.
(b) Check that there is continuity between terminals A3 and B3.
(c) Check that there is continuity between terminals A6 and B1.
If continuity is not as specified, replace the switch.
6. INSPECT SLIDING ROOF CONTROL RELAY CIRCUIT
Disconnect the connector from the relay and inspect the con-
nector on the wire harness side, as shown in the chart.
