DTC Descriptors

DTC P1EB2 00: Hybrid/EV Battery Interface Control Module 1 Not Programmed

DTC P1EB3 00: Hybrid/EV Battery Interface Control Module 2 Not Programmed

DTC P1EB4 00: Hybrid/EV Battery Interface Control Module 3 Not Programmed

DTC P1EB5 00: Hybrid/EV Battery Interface Control Module 4 Not Programmed

Circuit/System Description

When the battery energy control module is flash programmed, the hybrid battery interface module operating software and calibrations are provided to the battery energy control module. The hybrid battery interface module software and calibrations are then loaded to each of the hybrid battery interface modules from the battery energy control module. This operation is automatic and requires no operator action. At this point, if any of the hybrid battery interface control modules are not programmed correctly, the appropriate DTC is set.

This fault is internal to the hybrid battery interface control modules and no external circuits are involved.

Conditions for Running the DTC

    • The battery energy control module is awake and communicating.
    • The system voltage is at least 9 V.

Conditions for Setting the DTC

The hybrid battery interface control module is not programmed correctly.

Action Taken When the DTC Sets

    • The slave data that is incompatible with the battery energy control module software is set to Invalid, 0 V, and -40°C (-40°F).
    • DTCs P1EB2, P1EB3, P1EB4, and P1EB5 are type A DTCs.

Conditions for Clearing the DTC

    • The hybrid battery interface control module is programmed correctly.
    • DTCs P1EB2, P1EB3, P1EB4, and P1EB5 are type A DTCs.

Circuit/System Verification

If any of the DTCs P1EB2, P1EB3, P1EB4, and P1EB5 are set, program the K16 battery energy control module. The DTC should not reset.

If any of the DTCs reset, replace the A4 hybrid/EV battery pack.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.

    •  Drive Motor Battery Replacement and Shipping Preparation
    • Control Module References for control module replacement, programming and setup
