Voltage supply
See continuation on next page
This malfunction affects the voltage supply
of the control module.
This DTC is only stored, if it occurs the first
time the vehicle exceeds 6 km/h.
As soon as the supply voltage is again
within the valid voltage range, the 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-
