Circuit/System Description

The body control module (BCM) has designated circuits for monitoring vehicle system voltage. The BCM monitors the system voltage to ensure that the voltage stays within the proper range. Damage to components, and incorrect data may occur when the system voltage is out of range. The BCM monitors the system voltage over an extended length of time.

Conditions for Running the DTC

•  The BCM has power and ground.
•  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 s.

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 s.

B1517 5A

The battery voltage differs by 2 V on the BCM B+ circuits for 10 s.

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 .
•  The 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 C1 Battery terminals. The voltage should be between 12.6-15.0 V.
⇒ If not within the specified range, refer to Charging System Test .
2. Observe the scan tool BCM Battery Voltage parameter. Verify that the scan tool displays a value that is within 2 V of the battery terminal voltage.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connectors at the K9 Body Control Module.
2. Ignition OFF, test for less than 3.0 Ω between the ground circuit terminals listed below and ground.
  •  Terminal 1 X1
  •  Terminal 2 X2
  •  Terminal 3 X6
⇒ If not within the specified range, test the ground circuit for an open/high resistance.
3. Ignition ON, verify a test lamp illuminates between the B+ circuit terminals listed below and ground:
  •  Terminal 2 X1
  •  Terminal 3 X1
  •  Terminal 4 X1
  •  Terminal 1 X2
  •  Terminal 3 X2
  •  Terminal 4 X2
  •  Terminal 20 X4
  •  Terminal 3 X5
  •  Terminal 4 X5
⇒ If the test lamp does not illuminate, test the B+ circuits for a short to ground or an open/high resistance.
4. If the circuits test normal, test or replace the K9 Body Control Module.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
