Electrical Wiring Diagrams,
Troubleshooting & Component Locations - If ABS warning light does not come on,
check voltage of electrical system and test
wiring from terminal 32 of ABS control
module -J104- to instrument cluster for
short circuit to Ground (GND).
- The ABS warning lamp does not switch
off after 2 seconds. The red "brake system
malfunction" symbol lights up after 2
seconds. Check wire from terminal 32 of
ABS control module -J104- to instrument
cluster for short circuit to B+ and open
circuit.

DTC
00532
Voltage supply
Signal too small

Notes:

This malfunction affects the voltage supply
of the control module.
This DTC is only stored, if the malfunction
occurs at a vehicle speed above 6 km/h.
As soon as vehicle voltage is within the
valid voltage range again, the ABS,
ABS/EDL or ASR system is switched back
on and the warning lights turn off.
Open circuit or resistance too high
between voltage supply of terminal 15
and ABS control module -J104-
(terminal 1). Voltage jumps in vehicle system.Battery malfunctioning.
