Using TOYOTA Hand-Held Tester
WARNING: This page is about a different car, the 2003 Toyota Tundra, 2002 Toyota Tundra, and 2001 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Do not keep relay ON continuously for more than 5 seconds. When operating continuously, set intervals at no more than 20 seconds.
- To test actuator motor operation, connect TOYOTA hand held tester to DLC3. Start engine and let it run at idle. Select ACTIVE TEST mode on hand held tester. Check that operation sound of ABS actuator motor can be heard when motor relay is turned ON by hand held tester. If operation sound CANNOT be heard, replace ABS actuator, because motor has failed. Turn motor relay OFF.
- To inspect right front wheel solenoid, depress brake pedal and hold for about 15 seconds. Check that brake pedal cannot be depressed and that it does not pulsate. If brake pedal goes down or pulsates, replace ABS actuator because sealing condition of reduction solenoid valve is abnormal. Turn motor relay OFF.
- Depress brake pedal and hold. Check that brake pedal returns when motor relay is turned ON by hand-held tester. Check that brake pedal does not go down further when SFRH and SFRR solenoids are turned ON by hand-held tester. If brake pedal does go down, replace ABS actuator because holding solenoid valve operation is abnormal.
- Check that brake pedal goes down further when solenoids are turned OFF. If brake pedal does NOT go down, replace ABS actuator because reduction solenoid valve operation is abnormal. Check that brake pedal returns when motor relay is turned ON by hand-held tester. If brake pedal does not return, replace ABS actuator because motor has failed.
- Turn motor relay off and release brake pedal. To inspect other wheel solenoid operations, use same procedures and check solenoids in this order:
- Left Front Wheel: SFLH & SFLR
- Right Rear Wheel: SRRH & SRRR
- Left Rear Wheel: SRLR & SRLR
