Battery voltage is supplied to the electronic brake control module (EBCM) through fuse F6 in the instrument panel (I/P) fuse block, to terminal 20 of the EBCM connector. The voltage is present when the ignition switch is in the ON or START position.

1. Verify EBCM connector is secure.

⇒	If EBCM connector is not secure, repaire EBCM connection

2. Verify battery voltage is 11-14V.

⇒	If battery voltage is not as specified, test charging system, and/or replace battery if necessary.

1. Ignition OFF, disconnect the EBCM connector.
2. Ignition ON, check for 11-14V between the B+ circuit and ground.

⇒	If the voltage is not as specified, test the B+ circuit for a short to ground or an open/high resistance.

3. Test for less than 1 ohm between the ground circuits and ground.

⇒	If greater than the specified range, test the ground circuit for an open/high resistance. If the circuit tests normal, replace the BPMV/EBCM.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
