TCM Programming Procedures
- The transmission control module (TCM) must be programmed with
the proper software/calibrations. Ensure that the following conditions exist
in order to prepare for TCM programming:
| • | 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 TCM using the latest software matching the vehicle.
Refer to up-to-date Techline equipment user instructions.
- If the TCM fails to program, proceed as follows:
| • | Ensure that the TCM connection is OK. |
| • | Inspect the Techline equipment for the latest software version. |
| • | Attempt to program the TCM. If the TCM still cannot be programmed
properly, replace the TCM. |
