(MB991529) to earth terminal number 1 of the
diagnosis connector.

3. Depress the brake pedal and hold it.
4. Turn the ignition switch to the "ON" position.
5. After turning the ignition switch to the "ON",

release the pedal within three seconds. Repeat
this process of pressing and releasing the brake
pedal 10 continuous times.

6. Turn the ignition switch to the "LOCK" (OFF)

INSPECTION CHART FOR DIAGNOSIS
CODE

M1352011300708

Follow the inspection chart that is appropriate for the
diagnosis code.

NOTE: diagnosis code No.16, 52, 63

•

Code No.16 is cleared from the memory by turning the ignition switch to the "ACC" position. When the
system is properly reset, this code is also cleared from the memory.

•

Code No.52 and 63 are cleared from the memory by turning the ignition switch to the "ACC" position.

Diagnosis code
No.

DIAGNOSTIC TROUBLE CODE
PROCEDURES

Code No.11, 12, 13 and 14: ABS Sensor (Open Circuit or Short Circuit)

OPERATION

•

A toothed ABS rotor generates a voltage pulse as
it moves across the pickup field of each ABS
sensor.

•

The amount of voltage generated at each wheel
is determined by the clearance between the ABS
rotor teeth and the ABS sensor, and by the speed
of rotation.

•

The ABS sensors transmit the frequency of the
voltage pulses and the amount of voltage
generated by each pulse to the ABS-ECU.

•

The hydraulic unit modulates the amount of
braking force individually applied to each wheel
cylinder.

DIAGNOSIS CODE SET CONDITIONS
Diagnosis codes No.11, 12, 13 and 14 are set when
signal is not input due to breakage of the wires of the
four ABS sensors.

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

•

Malfunction of the ABS sensor

•

Damaged wiring harness or connector

•

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

DIAGNOSIS

STEP 1. MUT-II/III data list

Set MUT-II/III to data reading mode, and check the
data list items by driving the vehicle.

•

Item 01: Front right ABS sensor

•

Item 02: Front left ABS sensor

•

Item 03: Rear right ABS sensor

•

Item 04: Rear left ABS sensor

OK: The reading on the speedometer nearly
matches the indication on MUT-II/III, when
driving.

Q: Is the ABS sensor input normal?

YES :

This malfunction is intermittent. Refer to

GROUP 00, How to Use
Troubleshooting/Inspection Service Points

−

How to Cope With Intermittent Malfunction

P.00-6

NO :

Go to Step 2.

STEP 2. Inspect the ABS sensor.

Refer to

P.35B-68

Check items:

•

ABS sensor internal resistance: 1.24

−

1.64 k

Ω

•

Insulation between the ABS sensor body and the
connector terminals

Q: Is the ABS sensor damaged?

YES :

Replace it and then go to Step 8.

NO :

Go to Step 3.

STEP 3. Resistance measurement at ABS-ECU
connector B-03.

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

measure at the harness side.

(2) Measure the resistance between ABS-ECU

connector terminals 16 and 26, 9 and 10, 27 and
28, or 11 and 17.

Standard Value: 1.24

−

1.64 k

Ω

Q: Is the resistance between terminals 16 and 26, 9

and 10, 27 and 28, or 11 and 17 within the standard
value?

When resistances between all terminals are within
the standard value :

Erase the diagnosis code

memory, and recheck if any diagnosis code
sets. If diagnosis code No.11, 12, 13 or 14
sets, replace the hydraulic unit (integrated
with ABS-ECU). Then go to Step 8.

When resistance between terminals 16 and 26 is
not within the standard value :

Go to Step 4.

When resistance between terminals 9 and 10 is not
within the standard value :

Go to Step 5.

When resistance between terminals 27 and 28 is
not within the standard value :

Go to Step 6.

When resistance between terminals 11 and 17 is
not within the standard value :

Go to Step 7.
