Circuit/System Verification
1. Engine running, accessories OFF, measure and record the voltage at the battery voltage at the battery terminals. The voltage should be
between 12.6 and 15.0 V.
瀚慖f not within the specified range, refer to Charging System Test (See: Starting and Charging/Testing and Inspection/Component Tests
and General Diagnostics/Charging System Test).
2. Observe the scan tool EBCM Battery Voltage Signal parameter. The reading should be between 12.6 and 15.0 Volts.
瀚慖f greater than the specified range, replace the EBCM.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
