| | Checking control module grounding | 1. | Check the grounding of the control module by measuring the voltage across battery positive and pin E (5) of the control module connector and a good ground (e.g. a door hinge bolt). The voltage reading should be about 12 V. | 2. | If the voltage is not about 12 V, check the wiring harness for continuity or a short circuit by measuring the resistance across pin E (5) of the control module connector and the grounding point. The resistance should be > 1 ohm. If there is no fault in the lead, proceed fault diagnosis with .
