BRAKE SYSTEM – ANTI–LOCK BRAKE SYSTEM (ABS)

1. INSPECT BATTERY POSITIVE VOLTAGE
Battery positive voltage:
10–14 V
2. DISCONNECT CONNECTORS
(a) Disconnect the 2 connectors from the actuator.
(b) w/o TRAC:
Disconnect the 2 connectors from the control relay.
3. CONNECT ACTUATOR CHECKER (SST) TO ACTUATOR
(a) Connect the actuator checker (SST) to the actuator side wire harnesses via the sub–wire harnesses (SST), as shown.
w/o TRAC:
SST 09990–00150, 09990–00200, and 09990–00210
w/ TRAC:
SST 09990–00150, 09990–00210, 09990–00250, and 09990–00280
(b) Connect the red cable of the checker to the battery positive (+) terminal and the black cable to negative (–) terminal. Connect the black cable of the sub–wire harnesses to the battery negative (–) terminal or body ground.
SST 09990–00163
(c) Place "SHEET A" (SST) on the actuator checker.
