WARNING: This page is about a different car, the 2008 Saab 9-7X. However, it is still accessible from the selected car via links, so may be relevant.
If the TCM is reprogrammed, TCM Reprogramming must be performed. Refer to Service Programming System (SPS) .
Ensure the following conditions exist in order to prepare for TCM 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 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 the TCM connection is good.
- 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.
