July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector of the EBCM.
  2. Ignition ON, test for 11-16 volts between the B+ and the ground circuits of the EBCM.
    • If not within the specified range, test the circuits for an open, high resistance, or a short, or refer to Charging System Test .
  3. If all circuits test normal, replace the EBCM.
