Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the EBCM.

2. Test for less than 1 ohm between the ground circuits listed below and ground.

* Terminal 13

* Terminal 38

瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, verify that a test lamp illuminates between the B+ circuits listed below and ground.

* Terminal 1

* Terminal 25

瀚慖f the test lamp does not illuminate, test the appropriate circuit for a short to ground or an open/high resistance.

4. If all circuits test normal, replace the EBCM.

Repair Instructions

Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
