1. ABS-D AND ABS/ASR-E FAULT CODES

1.1 INTRODUCTION

If the electronic unit detects a system fault, this

fault is usually stored in the memory of the

electronic unit as a fault code.

Most system faults will also generate a warning.

1.2 FAULT CODE OVERVIEW

Fault code

Fault code description with possible cause

Symptom

1-1

Minimum value of wheel speed sensor signal
(F512) on pins B12 and B15 of the ECU is too low
due to:
-

too large an air gap between the wheel
speed sensor ring and the wheel speed
sensor

-

contact resistance on pin B12 and/or B15

-

ABS on front axle, left deactivated

-

ASR brake/engine control deactivated

1-2

Deviation of wheel speed sensor signal (F512) on
pins B12 and B15 of the ECU due to:
-

incorrect tyre size

-

ABS on front axle, left deactivated

-

ASR brake/engine control deactivated

1-3

Short circuit to supply in wheel speed sensor
(F512) on pins B12 and B15 of the ECU

-

ABS on front axle, left deactivated

-

ASR brake/engine control deactivated

1-4

Short circuit to earth in wheel speed sensor
(F512) on pins B12 and B15 of the ECU

-

ABS on front axle, left deactivated

-

ASR brake/engine control deactivated

1-5

Interruption in wheel speed sensor (F512) on pins
B12 and B15 of the ECU

-

ABS on front axle, left deactivated

-

ASR brake/engine control deactivated

1-6

Short circuit in wheel speed sensor (F512) on
pins B12 and B15 of the ECU

-

ABS on front axle, left deactivated

-

ASR brake/engine control deactivated

1-7

Incorrect sine-wave signal from wheel speed
sensor (F512) on pins B12 and B15 of the ECU
due to:
-

distorted wheel speed sensor ring

-

damaged wheel speed sensor ring

-

ABS on front axle, left deactivated

-

ASR brake/engine control deactivated

1-8

Deviation of wheel speed sensor frequency
(F512) on pins B12 and B15 of the ECU due to:
-

wheel slip of the left front wheel

-

ABS on front axle, left deactivated

-

ASR brake/engine control deactivated

1-9

Wiring of wheel speed sensor other than wheel
speed sensor (F512) connected to pins B12 and
B15 of the ECU

-

ABS on front axle, left deactivated

-

ASR brake/engine control deactivated

1-10

Unacceptable wheel speed sensor signal
frequency (F512) on pins B12 and B15 of the
ECU due to:
-

loose pole ring

-

wrong assessment by ECU

-

ABS on front axle, left deactivated

-

ASR brake/engine control deactivated

1-12

Frequency of wheel speed sensor signal (F512)
on pins B12 and B15 of the ECU is too high due
to:
-

unstable contact in wheel speed sensor
wiring

-

ABS on front axle, left deactivated

-

ASR brake/engine control deactivated

2-1

Minimum value of wheel speed sensor signal
(F513) on pins B10 and B13 of the ECU is too low
due to:
-

too large an air gap between the wheel
speed sensor ring and the wheel speed
sensor

-

contact resistance on pin B10 and/or B13

-

ABS on front axle, right deactivated

-

ASR brake/engine control deactivated

2-2

Deviation of wheel speed sensor signal (F513) on
pins B10 and B13 of the ECU due to:
-

incorrect tyre size

-

ABS on front axle, right deactivated

-

ASR brake/engine control deactivated
