Coupling Assembly Inspection

Coupling Assembly Inspection

^ Measure resistance between "a" terminal and "b" terminal of coupling connector (1).
If measured resistance is out of specification, check harness for open or short.
If OK, replace coupling assembly.

Coupling assembly resistance
: 2 - 3 ohms
