OPERATION
Refer to 

P.35B-46

.

COMMENT ON TROUBLE SYMPTOM

DIAGNOSIS

STEP 1. Check the ABS warning lamp circuit at 
ABS-ECU connector B-03.

(1) Disconnect ABS-ECU connector B-03.

(2) Connect ABS-ECU connector B-03 terminal 

number 12 to earth.

(3) Turn the ignition switch to the "ON" position.

Q: Does the ABS warning lamp go off?

YES : 

To check and reproduce the state of 

malfunction replace the hydraulic unit 
(integrated with ABS-ECU). Then go to Step 
3. If the malfunction is not reproduced, an 
intermittent malfunction is suspected. Refer 
to GROUP 00, How to Use 
Troubleshooting/Inspection Service Points
