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. If the circuit tests normal

and the B+ circuit fuse is open, replace the BPMV.

4. If all circuits test normal, replace the BPMV and verify DTC does not reset. If the DTC resets, replace the EBCM.

Repair Instructions

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

* Brake Pressure Modulator Valve Replacement (See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Hydraulic

Control Assembly - Antilock Brakes/Service and Repair)
