ABS FAULTCODE LIST
C1101
Battery vltg.
1
• Monitoring is activated after running of cut-in
Over volt
test and when the vehicle has exceeded 6km/h.
(>16V)
The battery voltage is measured continuously
and cyclically assessed.
C1102
Low volt
• If battery voltage is below 8.2V when ABS
(<8V)
regulation is active (brake operation and ABS
control as well as pressure increase with a
vehicle dynamic regulation occur.)
• If battery voltage is not in range of minimum
9.4V and maximum 17.4V when ABS
regulation is inactive (brake, operation and
ABS control as well as pressure increase with
vehicle dynamic regulation does not occur).
Effects:
• Correct function of ABS solenoid valves & of
return pump motor is no longer guaranteed.
• ABS is passive during the time span but not
switched off.
• ABS warning lamps are switched on.
• EBD is switched off at below 6.9V.
Note:
The solenoid valves are switched to passive
during under or over voltage, a possible return
flow of the return pump is suppressed during
the time span.
