Actuator Check
- Turn ignition off. Disconnect actuator and control relay electrical connectors. See Figure. Connect Test Harness (09990-00200 and 09990-00210) and Actuator Checker (09990-00150) to vehicle. Connect actuator checker positive and negative power cables to vehicle battery.
- Place Sheet "A" (09990-00163) on actuator checker. Start engine and let idle. Turn actuator checker SELECTOR switch to FRONT RH position. See Fig 1. Press and hold MOTOR switch for a few seconds. Press and hold brake pedal.NOTE: DO NOT press POWER switch for more than 10 seconds.
- Press POWER switch. When POWER switch is pressed, brake pedal should not go down. Release POWER switch. Brake pedal should lower. Press and hold MOTOR switch for a few seconds. Brake pedal should return. Release MOTOR switch. Release brake pedal.
- Press and hold MOTOR switch for a few seconds. Release MOTOR switch. Press brake pedal and hold for about 15 seconds. As brake pedal is being held, press MOTOR switch for a few seconds. Ensure brake pedal does not pulsate.
- Repeat steps 2) through 4) for FRONT LH, REAR RH and REAR LH by turning SELECTOR switch on actuator checker. When checking REAR LH position, press REAR LH switch, instead of POWER switch.
- After checking remaining wheels, press and hold MOTOR switch for a few seconds. Remove actuator checker and test harnesses.
- If any actuator solenoid does not test as indicated, check actuator solenoid resistance. Measure resistance of each actuator solenoid between 6-pin connector terminal No. 4 (White wire) and appropriate actuator solenoid connector. Resistance should be 1.2 ohms.
- Replace actuator if any actuator solenoid measures incorrectly. Reconnect vehicle harnesses to actuator and control relay. Clear diagnostic codes. See CLEARING CODES .
