Abs/TRAC Actuator Check
NOTE:
ABS/TRAC Actuator Checker (SST 09990-00150) is needed to perform actuator check.
- Turn ignition off. Ensure battery voltage is 10-14 volts. Disconnect ABS/TRAC 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 09990-00360 and STT 09990-00450) to ABS/TRAC actuator connectors.
- Connect FR TRC connector to White connector at sub-wire harness. See Fig 1. Connect ABS Actuator Checker (SST 09990-00150) to sub-wire harness. Connect Black cable of sub-wire harness to ground.
- Place SHEET "N" (SST 09990-00410) on ABS/TRAC actuator checker. Start engine and let it idle. Turn selector switch of ABS/TRAC 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 next step 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 brake pedal and hold it down for 15 seconds. With brake pedal depressed, press MOTOR switch for a few seconds. Ensure brake pedal does not pulsate. Replace ABS/TRAC actuator if it does not test as specified. See ABS/TRAC ACTUATOR under REMOVAL & INSTALLATION. Release brake pedal.
- Repeat steps 4- 6 for REAR positions of selector switch. See Fig 2. When inspecting FRONT LH position, it does not matter which selector switch position ABS/TRAC 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 "N" and sub-wire harness. Reconnect ABS/TRAC actuator connectors. Clear diagnostic trouble codes. 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 under DIAGNOSTIC TESTS. If relays are found to be faulty, replace relays and recheck actuator operation.
