Circuit/System Verification

  1. Engine running measure and record the voltage at the battery terminals. Verify that the battery voltage is 12.6-15.5 V
  2. Engine running, observe the scan tool EBCM Battery Voltage Signal parameter. The reading should be between 12.6 and 15.5 V
    • If not within the specified range, replace the EBCM.
