13B Logic Module Ground Circuit

Blue Logic Module Connector:





1. With ignition switch Off, disconnect blue connector from logic module.
2. Connect a digital ohmmeter between cavity 7 or 8 of blue connector and ground.
3. If ohmmeter indicates continuity with less than .5 ohm of resistance, proceed to Test 13 step C.
4. If ohmmeter indicates more than .5 ohm of resistance at one or both wires, repair ground circuit for high resistance.
5. If ohmmeter shows no continuity, repair wires for an open circuit to wiring harness splice. If no open is found, replace logic module.
