ON−VEHICLE INSPECTION
1. INSPECT BATTERY POSITIVE VOLTAGE
Battery positive voltage: 10 − 14 V
2. DISCONNECT CONNECTORS
(a) Disconnect the 2 connectors from the control relay.
(b) Disconnect the connector from the actuator.
3. CONNECT ACTUATOR CHECKER (SST) TO ACTUA-
TOR
(a) Connect the actuator checker (SST) to the actuator, con-
trol relay and body side wire harness through the sub−
wire harness C and E (SST) as shown in the illustration.
SST 09990−00150, 09990−00200, 09990−00210
(b) Connect the red cable of the checker to the battery posi-
tive (+) terminal and black cable to the negative (−) termi-
nal. Connect the black cable of the sub−wire harnesses
to the battery negative (−) terminal or body ground.
(c) Place the ”SHEET L” (SST) on the actuator checker.
SST 09990−00370
4. INSPECT BRAKE ACTUATOR OPERATION
(a) Start the engine, and run it at idle.
(b) Turn the selector switch of the actuator checker in
”FRONT” position.
(c) Push and hold in the MOTOR switch for a few seconds.
Make sure that you can hear the motor running.

sate.
(k) Release the brake pedal.
5. INSPECT FOR OTHER WHEELS
(a) Change the connection of the actuator checker (SST) to
the sub − wire harness E (SST) − from the sub − wire har-
ness MAIN connector to the SUB connector, or vice ver-
sa.
(b) Repeating (c) to (i) of the step 4, check the actuator opera-
tion same way.
6. INSPECT FOR REAR WHEEL
(a) Turn the selector switch to the ”REAR” position.
