Circuit/System Description

The battery charger will diagnose its own systems and determine when a fault condition is present. Diagnostics and system status is communicated from the battery charger to the hybrid/EV powertrain control module 2 through serial data. The hybrid/EV powertrain control module 2 is the host controller for DTC information.

The DTCs listed above for the battery charger are internal measurements that verify the charger is performing properly. The battery charger measures internal voltages, currents, and temperatures and verifies they are within the proper range.

Conditions for Running the DTC

These DTCs are internal faults of the battery charger. The vehicle needs to be connected to an AC supply and the battery charger is charging the vehicle.

Conditions for Setting the DTC

These DTCs are internal faults of the battery charger.

Action Taken When the DTC Sets

•	DTC P0D39-P0D3B, P0D49-P0D54, P1ECB-P1ECD, P1ED0-P1ED9, P1ED9, P1EDB, P1EDC, P1EDE-P1EED or P1EFF-P1F02 are type A and B DTCs.

•	Disables high-voltage battery charging.

Conditions for Clearing the DTC

DTC P0D39-P0D3B, P0D49-P0D54, P1ECB-P1ECD, P1ED0-P1ED9, P1ED9, P1EDB, P1EDC, P1EDE-P1EED or P1EFF-P1F02 are type A and B DTCs.

Circuit/System Verification

Danger: Always perform the High-Voltage Disabling procedure prior to servicing any High Voltage component or connection. Personal Protection Equipment (PPE) and proper procedures must be followed.

The High-Voltage Disabling procedure will perform the following tasks:

•	Identify how to disable high voltage.

•	Identify how to test for the presence of high voltage.

•	Identify conditions under which high voltage is always present and personal protection equipment (PPE) and proper procedures must be followed.

Before working on any high-voltage system, be sure to wear the following Personal Protection Equipment:

•	Safety goggles with appropriate side shields when within 15 metres (50 feet) of the vehicle, either indoors or outdoors.

•	Certified and up-to-date Class "0" Insulation gloves rated at 1000 V with leather protectors.

-	Visually and functionally inspect the gloves before use.

-	Wear the Insulation gloves with leather protectors at all times when working with the high-voltage battery assembly, whether the system is energised or not.

Failure to follow the procedures exactly as written may result in serious injury or death.

Verify that DTC P0D39-P0D3B, P0D49-P0D54, P1ECB-P1ECD, P1ED0-P1ED9, P1ED9, P1EDB, P1EDC, P1EDE-P1EED or P1EFF-P1F02 is not set.

⇒	If DTC is set, disable the high voltage at the T18 battery charger. Refer to High Voltage Disabling . Replace the T18 battery charger.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
