Abs Malfunction Indicator Lamp - Mercedes-Benz G Series Operator's Manual

ABS malfunction indicator lamp

The ABS malfunction indicator lamp in the
ABS instrument cluster comes on with the
electronic key in starter switch position 2
and should go out with the engine running.
When the ABS malfunction indicator lamp symbol and
warning in the instrument cluster remains illuminated
while the engine is running, it indicates that the ABS
has detected a malfunction and has switched off. In this
case, the brake system functions in the usual manner,
but without antilock assistance.
A malfunctioning ABS control unit can possibly affect
the operation of other systems (e.g. Navigation,
Automatic transmission). Be guided accordingly with
respect to the use of those systems and have the system
checked at your authorized Mercedes-Benz Light Truck
Center as soon as possible.
With the ABS malfunctioning the BAS, ESP, EBB and
4-ETS are also switched off. The malfunction indicator
lamps and malfunction messages in the multifunction
display come on with the engine running.

If a warning tone sounds for 5 seconds and the warning
lamps - and É are displayed in the instrument
cluster, the EBB has a malfunction and is switched off.

switched off. When the voltage is above this value again,
the malfunction indicator lamp should go out and the
ABS is operational.
