STEP 2. Check the harness wire between 
junction block connector C-202 terminal 8 and 
ABS-ECU connector B-03 terminal 20.

NOTE: 

After inspecting ABS-ECU connector B-03, junction 
block connector C-202 and intermediate connector 
C-106, inspect the wire. If any of these connectors is 
damaged, repair or replace it. Then go to Step 5.

Q: Is the harness wire between junction block 

connector C-202 terminal 8 and ABS-ECU 
connector B-03 terminal 20 damaged?

YES : 

Repair it and go to Step 5.

NO : 

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

NOTE: 

After inspecting ABS-ECU connector B-03, diagnosis 
connector C-24, and intermediate connectors C-02, 
C-104 and C-105, inspect the wires. If any of these 
connectors is damaged, repair or replace it. Then go 
to Step 5.

Q: Is any of the harness wires between ABS-ECU 

connector B-03 (terminals 4 and 13) and diagnosis 
connector C-24 (terminals 1 and 7) damaged?

YES : 

Repair it and go to Step 5.

NO : 

Go to Step 4.

STEP 4. Check the harness wires between 
ABS-ECU connector B-03 (terminals 2 and 18) 
and earth (No.9).

Q: Is any of the harness wires between ABS-ECU 

connector B-03 (terminals 2 and 18) and earth 
(No.9) damaged?

YES : 

Repair it and then go to Step 5.

NO : 

Check the troubleshooting condition. To 
reproduce the troubleshooting state replace 
the hydraulic unit (integrated with 
ABS-ECU).Then go to Step 5. If the state of 
failure is not reproduced then a intermittent 
malfunction is suspected. Refer to GROUP 
00, How to Use Troubleshooting/Inspection 
Service Points

STEP 5. Retest the system.

Q: Does the MUT-II/III communicate with the ABS 

system?

YES : 

The procedure is complete.

NO : 

Start over at Step 1.

INSPECTION PROCEDURE 2: When the Ignition Key is Turned to the "ON" position (Engine Stopped), 
the ABS Warning Lamp does not Illuminate.

OPERATION

•

The ABS warning lamp is lit up by transistor 
control in the ABS-ECU. However, the 
relationship of the reverse circuit movement in 
the combination meter will vary from usual in 
terms of transistor ON/OFF and ABS warning 
lamp ON/OFF, in that the ABS warning lamp will 

lamp up when the transistor is turned OFF for this 
circuit. This is how the ABS warning lamp lights 
up even when the ABS-ECU connector is 
connected improperly or if the ABS-ECU function 
has terminated.

•

The ABS-ECU also lights up the ABS warning 
lamp during the initial check (approximately 3 
seconds) when the ignition switch is turned to the 
"ON" position in addition to when the system is 
malfunctioning.
