Actuator Check

NOTE: Actuator check is performed using manufacturer's actuator checker (09990-00150) and harness adapters. If actuator does not operate as described, check solenoid relay and motor relay (DTCs 11, 12, 13 and 14). If solenoid and/or motor relay are abnormal, replace appropriate relay and repeat actuator check.
  1. Ensure battery voltage is 10-14 volts and charging system is working properly. Turn ignition off. Disconnect 2 actuator electrical connectors. Connect Actuator Checker (09990-00150), following manufacturer's instructions. Connect Red cable of checker to battery positive terminal and Black cable to negative battery terminal. Install Sheet "P" (09990-00430) onto actuator checker.
  2. Start engine and run at idle. Turn actuator checker selector switch to FRONT LH position. Press and hold MOTOR switch for a few seconds. Press and hold brake pedal.
    NOTE: DO NOT press MAIN switch for more than 10 seconds.
  3. Press MAIN switch. When MAIN switch is pressed, brake pedal should not go down. Release MAIN switch. Brake pedal should go down. Press and hold MOTOR switch for a few seconds. Brake pedal should return. Release MOTOR switch. Release brake pedal.
  4. 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. Brake pedal should not pulsate.
  5. Repeat steps  2 through  4 for FRONT RH, REAR RH, and REAR LH by setting selector switch to appropriate positions. When checking FRONT RH position, press FRONT RH switch, instead of MAIN switch.
  6. After checking remaining wheels, press and hold MOTOR switch for a few seconds. Remove actuator checker. Install actuator connectors. Clear DTCs. See CLEARING DIAGNOSTIC TROUBLE CODES .
