Abs Actuator Check
NOTE:
ABS Actuator Checker (SST 09990-00150) is needed to perform actuator check.
- Turn ignition off. Ensure battery voltage is 10-14 volts. Disconnect ABS actuator electrical connectors. Connect ABS Actuator Checker (SST 09990-00150) positive and negative power cables to vehicle battery. Connect sub-wire Harness (SST 09990-00250, SST 09990-00300 and SST 09990-00360) to ABS actuator connectors. Connect ABS Actuator Checker (SST 09990-00150) to sub-wire harness. See Fig 1. Connect Black cable of sub-wire harness to ground.
- Place SHEET "A" (SST 09990-00163) on ABS actuator checker. Start engine and run at idle. Turn selector switch of ABS actuator checker to FRONT RH position. See Fig 2.
- Press MOTOR switch for a few seconds. Depress and hold brake pedal down until step 4 is completed.NOTE: DO NOT keep MAIN switch pressed for more than 10 seconds.
- Press POWER switch, and ensure brake pedal does not go down. Release POWER switch. Brake pedal should go down. Press MOTOR switch for a few seconds, and ensure brake pedal returns. Release brake pedal.
- Press MOTOR switch for a few seconds then release. Depress brake pedal and hold down for 15 seconds. With brake pedal depressed, press MOTOR switch for a few seconds. Ensure brake pedal does not pulsate. Replace ABS actuator if actuator does not test as specified. See ABS ACTUATOR under REMOVAL & INSTALLATION. Release brake pedal.
- Repeat steps 3- 5 for FRONT LH and REAR RH positions of selector switch. See Fig 2. When inspecting REAR LH position, it does not matter which selector switch position ABS actuator checker is in. When inspecting REAR LH, push REAR LH switch instead of POWER switch.
- After all wheels are checked, press MOTOR switch for a few seconds. Turn engine off. Remove actuator checker, SHEET "A" and sub-wire harness. Reconnect actuator harness connectors. Clear Diagnostic Trouble Codes (DTC). See CLEARING DIAGNOSTIC TROUBLE CODES under DIAGNOSIS & TESTING.
- If actuator does not operate as specified, check ABS solenoid and ABS motor relay operation. See DTC 11 OR 12: ABS SOLENOID RELAY CIRCUIT and DTC 13 OR 14: ABS MOTOR RELAY CIRCUIT . Replace relays as necessary and recheck actuator operation.
