Safety precautions and fundamental
points regarding troubleshooting


Note:

The ABS is a vehicle safety system; the
appropriate knowledge is necessary to work on
the system.

In order to check complaints and to be able to
carry out pin-pointed troubleshooting, the
Diagnostic Trouble Code (DTC) memory must
be checked before commencing work on the
ABS system.

Only separate connectors when the ignition is
switched off.

Observe the appropriate instructions regarding
the handling of brake fluid.
Repair Manual, Brake System, Repair Group
47
ABS malfunctions are indicated by the ABS
warning light illuminating. Certain malfunctions
will only be recognized at speeds above 20
km/h (approx. 13 mph) (carry out road test).

If the ABS -K47- and the brake system -K118-
warning lights do not illuminate, but the brake
system is not functioning correctly then the
malfunction must be sought in the conventional
braking system.
