Drive Motor Generator Battery Control Module Programming and Setup

Drive Motor Generator Battery Control Module Programming and Setup

The following service procedures require either a programming or a setup event be performed for a complete repair. The battery energy control module (BECM) is located inside the drive motor generator battery assembly, and can be serviced separately.

Battery Energy Control Module (BECM) Replacement

If the BECM is replaced, BECM Reprogramming must be performed. Refer to Service Programming System (SPS) (Programming and Relearning).

Battery Energy Control Module (BECM) Reprogramming

When BECM Reprogramming must be performed, refer to Service Programming System (SPS) (Programming and Relearning).

Ensure the following conditions exist in order to prepare for BECM programming or reprogramming:

* The battery is fully charged.
* The ignition switch is in the RUN position.
* The Techline equipment cable connection at the data link connector (DLC) is secure.

Program the BECM using the latest software matching the vehicle. Refer to up-to-date Techline equipment user instructions.

If the BECM fails to program, proceed as follows:

Important: If the DLC connection or the control module programming sequence is disrupted during a programming event the BECM may stop communicating, it will be necessary to remove and reinstall the BECM power fuse to re-establish communications with the BECM. Control module programming can then be reinitiated.


* Ensure the DLC and BECM connections are good.
* Inspect the Techline equipment for the latest software version.
* Attempt to program the BECM. If the BECM still cannot be programmed properly, replace the BECM.

Battery Energy Control Module (BECM) Setup
