Circuit/System Testing

  1. Ignition OFF, disconnect the EBCM connector.
  2. Ignition ON, check for 8-14V between EBCM connector terminal 2 and ground with brake pedal applied and less than 1.5V with braked pedal released.
    • If the voltage is not as specified, test the circuit for a short to ground or an open/high resistance.
  3. Ignition ON, check for 11-14V between terminals, 12, 24, 34 and ground.
    • If the voltage is not as specified, test the B+ circuit for a short to ground or an open/high resistance.
  4. Test for less than 1 ohm between the terminals 1, 13 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.
