* The ignition is not in the START position.
Conditions for Setting the DTC
B1517 03
* The battery voltage is less than 11 V.
* The engine speed is greater than 1,100 RPM.
* The above conditions are met for 15 seconds.
B1517 07
* The battery voltage is greater than 16 V.
* The engine speed is greater than 1,100 RPM.
* The above conditions are met for 15 seconds.
B1517 5A
The battery voltage differs by 2 V on the BCM battery sense circuits for 10 seconds.
Action Taken When the DTC Sets
* The instrument panel cluster illuminates the charge indicator.
* The driver information center displays the SERVICE BATTERY CHARGING SYSTEM warning message.
Conditions for Clearing the DTC
* The DTC will clear current status when fault is no longer present.
* The history DTC will clear after 50 consecutive ignition cycles have occurred without a malfunction.
Diagnostic Aids
* A high or low voltage DTC set in multiple modules indicates a concern in the charging system. Refer to Charging System Test (See:
Starting and Charging/Testing and Inspection/Component Tests and General Diagnostics/Charging System Test).
* This DTC may be set by overcharging with a battery charger, or by jump starting.
* Inspect the ground connection , and ensure that it is clean and tight.

Circuit/System Verification
1. Engine running, accessories OFF, measure and record the voltage at the battery voltage at the C1 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 BCM Battery Voltage parameter. Verify that the scan tool displays a valve that is within 2 V of the battery terminal
