Specified value: ∞ Ω.
If the measured value does not correspond
to the specified value (there is a short-
circuit between the cables):
Eliminate the fault according to the
–
current flow diagram
diagrams and Fitting
If the measured value does corresponds to
the specified value (there is no short-circuit
between the cables):
Check the CAN databus cables for a short
–
circuit to positive and/or to earth.
If no short-circuit is found:
Connect test box -V.A.G 1598/22 - at
