Circuit/System Testing
- Ignition OFF. Disconnect the harness connectors at the BCM. Verify that there is less than 1.0 ohm between the ground circuits X1 17- 19- 20/X2 50 and the negative battery terminal.
- If greater than the specified value, test the affected ground circuit for an open/high resistance.
- Ignition ON. Test for 9.5-13.5 volts between the battery positive voltage circuits X1 terminals 50- 51- 52/ignition 1 circuits X1 terminals 22- 23 and the ground circuit X2 terminal 50 of the BCM.
- If not within the specified range, test the affected battery positive voltage circuits/ignition 1 circuits for a short to ground or an open/high resistance.
- If all the circuits test normal, replace the BCM.
