Abs/TRAC 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/TRAC actuator connectors, located behind right front fender liner. 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 SST 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 to sub-wire harness. Connect Black cable of sub-wire harness to ground.
- Place SHEET "A" (SST 09990-00163) on ABS/TRAC actuator checker. Start engine and operate it at idle. Turn selector switch of ABS/TRAC actuator checker to FRONT RH position. See Fig 2.
- Press MOTOR switch for a few seconds. Depress and hold brake pedal down until step 5 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 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 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/TRAC 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 & TRAC MOTOR RELAY CIRCUIT . Replace relays as necessary and recheck actuator operation.
