print-out Possible cause
Repair
No DTC
recognized If "No DTC recognized" appears after carrying out repairs, On Board
Diagnostic (OBD) is ended.
If, despite "No DTC recognized" appearing in the display, the ABS system
does not function properly, then proceed as follows:
1. Carry out road test exceeding 20 km/h (13 mph),
2. Again check DTC memory, if there is still no DTC stored,
3. Continue troubleshooting without OBD and work through the complete
Electrical check Page 01

ABS Mark 60 On Board
Diagnostic (OBD), vehicles
from my 10.00
There are four versions of the ABS Mark 60.

ABS

ABS/EDL/ASR

ABS/EDL/ASR/ESP with front wheel drive

ABS/EDL/ASR/ESP with 4MOTION
Each version has its own control module. The
control modules can be coded accordingly
through coding bridges via tester VAS 5051 or
V.A.G 1551.
The ESP (Electronic Stabilization Program) is
an electronic dynamics Program (EDP). It
stabilizes the vehicle when oversteering or
understeering. The ESP works over the whole
speed range. If the ESP is regulating the
system the ESP warning lamp will flash 3 times
per second.

The ESP is a further extension of the
familiar vehicle safety systems.
ESP increases control over the vehicle in
critical situations. It reduces the danger of
skidding and increases the steering control
when compared with familiar vehicle safety
systems.

Sporadic (irregular) malfunctions will also be
recognized and stored. But if malfunctions
affecting the data bus system do not occur again
within the next 15 vehicle start and driving off
sequences, or other malfunctions within the next
50 vehicle start and driving off sequences, they
will be erased from DTC memory except for the
malfunction "Control module faulty" (forget-
malfunction counter).
After switching on the ignition and/or starting the
engine, the ABS warning light -K47- and the ESP
control lamp -K155- will light up for approx. 2
seconds.
During this period a test sequence (self-check) is
run in the control module for the following
functions:

To check if the supply voltage is at least 10.0
Volt,

To check control module including the valve
windings,

To check the coding of the control module,

A static check of the speed sensor (no speed
signal),

If the wheel speed signal is not OK after the car
has been driven and a speed of approx. 20
km/h (approx. 13 mph) has been exceeded, the
ABS warning light -K47- will light up again.

Diagnostic Trouble Code (DTC) memory
A non-volatile memory ensures that the contents
of the DTC memory are retained even without
voltage.
Data output takes place on V.A.G 1551 scan tool
in operating mode 1 (rapid data transfer), and on
tester VAS 5051 in operating mode "vehicle
OBD".
