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 "O" (SST 09990-00420) 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 brake pedal and hold it in position until step 4 is completed.NOTE: DO NOT keep POWER 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 it. Depress and hold brake pedal for 15 seconds. With brake pedal depressed, press MOTOR switch for a few seconds. Ensure brake pedal does not pulsate. Replace ABS actuator if it does not test as specified. See ABS ACTUATOR under REMOVAL & INSTALLATION. Release brake pedal.
- Repeat steps 3- 5 for REAR positions of selector switch. See Fig 2. When inspecting FRONT LH position, it does not matter which selector switch position ABS actuator checker is in. When inspecting FRONT LH, push FRONT 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 "O" and sub-wire harness. Reconnect actuator harness connectors. Clear diagnostic trouble codes. See CLEARING DIAGNOSTIC TROUBLE CODES under DIAGNOSIS & TESTING.
- If actuator does not operate as specified, check ABS solenoid relay and ABS motor relay operation. See DTC 11 OR 12: ABS SOLENOID RELAY CIRCUIT and DTC 13 OR 14: ABS MOTOR RELAY CIRCUIT under DIAGNOSTIC TESTS. If relays are found to be faulty, replace relays and recheck actuator operation.
