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

2. Program the TCM using the latest software matching the vehicle. Refer to up-to-date Techline equipment user instructions.
3. If the TCM fails to program, proceed as follows:

1. Ensure that the TCM connection is OK.
2. Inspect the Techline equipment for the latest software version.
3. Attempt to program the TCM. If the TCM still cannot be programmed properly, replace the TCM.
