TROUBLESHOOTING

ANTI-SKID BRAKING SYSTEM (ABS)

35B-47

COMMENT ON TROUBLE SYMPTOM
Possible causes include the combination meter 
power circuit, disconnected earth circuit, dead lamp 
bulb, or short circuited ABS warning lamp.

PROBABLE CAUSES
The most likely causes for this case are:

•

Blown fuse

•

Damaged wiring harness or connector

•

Burnt out ABS warning lamp bulb

•

Combination meter defect

•

Malfunction of the hydraulic unit (integrated with 
ABS-ECU)

DIAGNOSIS

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

(1) Disconnect ABS-ECU connector B-03.
(2) Turn the ignition switch to the "ON" position.

Q: Does the ABS warning lamp illuminate?

YES : 

To check and reproduce the state of 

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

STEP 3. Voltage measurement at the combination 
meter connector C-04.

(1) Disconnect connector C-04, and check at the 

harness side.

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

(3) Measure the voltage between terminal 42 and 

earth.

OK: System voltage

Q: Is the check result normal?

YES : . 

Go to Step 5.

NO : . 

Go to Step 4.

STEP 4. Check the harness wire between 
junction block connector C-203 terminal 6 and 
combination meter C-04 terminal 42.

NOTE: After inspecting junction block connectors 
C-203 and C-205, and combination meter connector 
C-04, inspect the wire. If any of these connectors is 
damaged, repair or replace it. Then go to Step 7.

Q: Is the harness wire between junction block 

connector C-203 terminal 6 and combination meter 
C-04 terminal 42 damaged?

YES : 

Repair the harness wire and go to Step 7.

NO : 

This malfunction is intermittent. Refer to 
GROUP 00, How to Use 
Troubleshooting/Inspection Service Points
