TCM Coding & Programming: Programming
Programming refers to the instructions that the TCM is to follow. The TCM is programmed to apply certain shift maps according to operating conditions such as vehicle speed, engine speed, engine temperature, engine load and throttle position. This information can be entered into the TCM via an updated EPROM or through flash programming. Flash programmable control units use a EEPROM which is Electronically Erasable. The EEPROM is also soldered into the TCM and cannot be removed or replaced. Flash programmable TCM's can be programmed up to 14 times (with a new TCM). See Fig 1 .
NOTE:
Always clear adaptations after programming.
NOTE:
Do not program a TCM to correct a complaint unless there is a specific TSB that covers the issue.
