Circuit/System Testing

  1. Ignition OFF, disconnect the EBCM connector.
  2. Ignition ON, check for 10-16V between the EBCM terminal 16 and ground with brake pedal applied.
    • 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 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.
  4. Test for less than 1 ohm between the ground circuit 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.
