TROUBLESHOOTING

ANTI-SKID BRAKING SYSTEM (ABS)

35B-39

NOTE:

After inspecting intermediate connector A-14,
inspect the wire. If the connector is damaged, repair
or replace it. Then go to Step 3.

Q: Is any harness wire between fusible link number 3

and ABS-ECU connector B-03 (terminal 1 and 19)
damaged?

YES :

Repair it and go to Step 3.

NO :

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

How to Cope With Intermittent Malfunction

P.00-6

.

STEP 3. Check whether the diagnosis code is
reset.

Q: Is diagnosis code No.41, 42, 43, 44, 52, 53 or 55

set?

YES :

Start over at Step 1.

NO :

The procedure is complete.

SYMPTOMS

M1352011400664

NOTE: If steering movements are made when
driving at high speed, or when driving on road
surfaces with low frictional resistance, or when
passing over bumps, the ABS may operate although
sudden braking is not being applied. Because of this,
when getting information from the customer, check if
the problem occurred while driving under such
conditions as these.

NOTE: During ABS operation, the brake pedal may
vibrate a little or may not be able to be pressed. Such
conditions are due to intermittent changes in
hydraulic pressure inside the brake line to prevent
the wheels from locking. This is normal.

OPERATION

•

The diagnostic output is made from the
ABS-ECU (terminal 13) to the diagnosis output
terminal (terminal 7) of the diagnosis connector.

•

When the diagnosis connector's diagnosis test
mode control terminal (terminal 1) is grounded,
the ABS-ECU (terminal 4) will go into diagnosis
mode.

COMMENT ON TROUBLE SYMPTOM
When communication with the MUT-II/III is not
possible, the cause is probably an open circuit in the
ABS-ECU power circuit or an open circuit in the
diagnostic output circuit.

PROBABLE CAUSES
The most likely causes for this case are:

•

Blown fuse

•

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) Start the engine.

(3) Measure the voltage between terminal 20 and

earth.

OK: System voltage

Q: Is the check result normal?

YES :

Go to Step 3.

NO :

Go to Step 2.
