Charging System - 5.0L 32V Ti-VCT — 2016 workshop reference 4056

pushed-out pins – install new pins as necessary

Were any concerns present?

Yes	CORRECT the cause as necessary.
No	GO to H9

H9 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

Ignition OFF. Disconnect and inspect all BCM connectors. Repair:

corrosion (install new connector or terminals – clean module pins) damaged or bent pins – install new terminals/pins pushed-out pins – install new pins as necessary

Reconnect the BCM connectors. Make sure they seat and latch correctly. Operate the system and determine if the concern is still present.

Is the concern still present?

Yes	CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, Click here to access Guided Routine (BCM).
No	The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.

Battery Current Sensor Faults

Refer to Wiring Diagrams Cell 12 for schematic and connector information.

Normal Operation and Fault Conditions

For information on the battery current sensor, REFER to: Charging System - System Operation and Component Description (414-00 Charging System - General Information, Description and Operation).

Diagnostic Trouble Code (DTC) Fault Trigger Conditions

DTC	Description	Fault Trigger Conditions
	B130C:12 Load Shed Control Circuit Short To Battery	This DTC sets in the BCM when the BCM senses a short in the battery current sensor control circuit.
	B130C:14 Load Shed Control Circuit Short To Ground or Open	This DTC sets in the BCM when the BCM senses an open or ground in the battery current sensor control circuit.
B1438:03	Battery Current Sensor, FM (Frequency Modulated) / PWM (Pulse Width Modulated) Failure	This DTC sets in the BCM when the BCM does not indicate current from the battery current sensor.

PINPOINT TEST I : BATTERY CURRENT SENSOR FAULTS

NOTE: Make sure battery voltage is greater than 12.2 volts prior to and during this pinpoint test.

NOTE: Do not have a battery charger attached during vehicle testing.

I1 RETRIEVE DIAGNOSTIC TROUBLE CODES (DTCS)

Ignition ON. Using a diagnostic scan tool, perform the PCM self-test

Is DTC P0562 present?

Yes	GO to Pinpoint Test B
No	For DTC P0A5A, GO to I2 For DTC P0A5B, GO to I6 For DTC P0A5C, GO to I10
