INSPECTION
Operation Check of Rear Wiper Motor
1. Check that the motor operates continuously when
12V is connected to the (a) terminal and ground
is connected to the (b) terminal of the motor.
2. Start the motor again.
Disconnect the ground from the (b) terminal, and
then connect the ground to the motor body im-
mediately. Check that the motor shaft reaches the
auto-stop position, and that there is conductivity
through the grounding of the motor body.
Note:
Be sure to re-install the rubber seal correctly.
Operation Check of Rear Washer Motor
1. Using a voltmeter, measure the voltage between
the (b) terminal and a body ground with the igni-
tion switch ON.
2. If no voltage, check the fuse or repair the harness.
3. If the (b) terminal voltage is 12 V, connect the (a)
terminal to a body ground.
4. If the washer motor does not operate, replace the
washer motor.

ON-VEHICLE INSPECTION (USING ACC CHECKER 49 9200 010)
76G15X-072
Note:
When checking the actuator on '88 models with EC-AT using this checker, the checker
should be modified as shown below in order to avoid damage of the EC-AT control unit.
Modification Procedure
1. Cut the wire at terminal no.6 indicated on ACC
checker connector.
2. Tape exposed end of wire cut in step 1 as shown.
This modification does not affect the usage of the ACC
checker except when used on the '81 RX-7 and 626
models. When the modified ACC checker is used on
these models, use a jumper wire and jump across
terminal no.6 to 3 indicated on ACC checker connec-
tor as shown.
