relay -J105-.
ABS return flow
pump relay -J105-
installed
- Use VAG1598/20 to
measure voltage
between terminals 20
and 29.
Voltage should be
between 10.5 to
14.5 V between
terminals 20 and
29.
- Switch on ignition for
max. 10 seconds and
switch off again. ABS return flow
pump -V39- runs - If you do not measure any
voltage between terminals 20
and 29, replace the relay.
- If you measure voltage
between terminals 20 and 29,
the ABS return flow pump is
malfunctioning. Replace ABS
hydraulic unit -N55-.
