Checking Control Module Grounding

1 Check the grounding of the control module by measuring the resistance across pin E (5) of the control module and a good ground (e.g. a door hinge bolt).
The resistance should be <=1 ohm.
2 Check the wiring for continuity or a short circuit by measuring the resistance across pin E (5) of the control module and the grounding point.
The resistance should be <=1 ohm.
