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

Circuit/System Verification

  1. If the DTC is history, refer to Charging System Test 
  2. Start the engine, record the voltage at the battery terminals. Observe the battery voltage signal parameter in the EBCM data list. Voltages should not differ by more than 1 volt.
    • If more than 1 volt, replace the EBCM.
