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:
- 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.
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 re-initiated.
