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.
