Note:
The operation manual for the VAS1978 wiring
harness repair kit generally forbids the repair of
any lines in the ABS or related systems. This rule
only pertains to the shielded lines in these
systems.
Ignition and electrical consumers switched
off before beginning testing (headlights,
lighting, fan, etc.).
For steps 13 through 16, raise the vehicle
until the wheels rotate freely. On vehicles
with manual transmission put the gear shift
lever in neutral. On vehicles with automatic
transmission move the selector lever to
position "N".
