STEP 4. MUT-II/III data list

Set MUT-II/III to data reading mode, and check the
data list item.

•

Item 36: Stop lamp switch

OK:
Brake pedal stepped down: ON
Brake pedal released: OFF

Q: Is the stop lamp switch input normal?

YES :

This malfunction is intermittent. Refer to

.

NO :

Go to Step 5.

STEP 5. Voltage measurement at the ABS-ECU
connector B-03.

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

measure at the harness side.

(2) Depress the brake pedal to turn on the stop lamp

switch.

(3) Measure the voltage between terminal 3 and

earth.

OK: System voltage

Q: Is the check result normal?

YES :

Erase the diagnosis code memory, and

recheck if any diagnosis code sets. If
diagnosis code No.33 set, replace the
hydraulic unit (integrated with ABS-ECU).
Then go to Step 7.

NO :

Go to Step 6.

STEP 6. Check the harness wire between
ABS-ECU connector B-03 terminal 3 and stop
lamp switch connector C-101 terminal 1.

NOTE:

After inspecting ABS-ECU connector B-03,
intermediate connectors C-16 and C-104, and stop
lamp switch connector C-101, 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 ABS-ECU connector

B-03 terminal 3 and stop lamp switch connector
C-101 terminal 1 damaged?

YES :

Repair it and then go to Step 7.

NO :

This malfunction is intermittent. Refer to

STEP 7. Check whether the diagnosis code is
reset.

Q: Is diagnosis code No.33 set?

YES :

Start over at Step 1.

NO :

The procedure is complete.

Code No.41, 42, 43, and 44: ABS Solenoid Valve inside Hydraulic Unit (Open Circuit or Short Circuit)
Code No.52: Valve Relay Problem (Stays off)
Code No.53: Motor Relay Problem (Stays off)
Code No.55: Motor System (Seized Pump Motor)

OPERATION
Power is continuously supplied to the ABS-ECU
through fusible link number 3 to operate the solenoid
valve and motor.

DIAGNOSIS CODE SET CONDITIONS
These codes are set if the power supply circuit of
solenoid valve or motor is open or shorted.

PROBABLE CAUSES
The most likely causes for these diagnosis codes to
set are:

•

Damaged wiring harness or connector

•

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

DIAGNOSIS

STEP 1. Voltage measurement at the ABS-ECU
connector B-03.

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

measure at the harness side.

(2) Measure the voltage between terminal 1 and

earth, and 19 and earth.

OK: System voltage

Q: Is the check result normal?

YES :

Erase the diagnosis code memory, and

recheck if any diagnosis code sets. If
diagnosis code No.41, 42, 43, 44, 52, 53, or
55 set, replace the hydraulic unit (integrated
with ABS-ECU). Then go to Step 3. If
diagnosis code No.41, 42, 43, 44, 52, 53, or
55 is not set, an intermittent malfunction is
suspected. Refer to GROUP 00, How to
Use Troubleshooting/Inspection Service
