Battery Energy Control Module (BECM) Reprogramming

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

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.
