TCM Programming - Aw60 And F21-250

PROGRAMMING THE TRANSMISSION CONTROL MODULE (TCM) 

NOTE:

When replacing a Transmission Control Module (TCM), check for any software updates. Update the controller if any updates are available after installation.

NOTE:

Failure to properly program the TCM may result in the illumination of the Malfunction Indicator Lamp (MIL) and setting DTC(s).

NOTE:

While performing the TCM programming procedure, the vehicle battery must be maintained between 10 and 16 volts. Ambient temperature must be between 0° C (32° F) 60° C (140° F). Vehicle must be in Park with brake pedal depressed.

NOTE:

The total number of TCM reflashes and/or reflash attempts must be limited to a maximum of 50 times. The TCM is considered defective if more than 50 reflashes and/or reflash attempts have occurred.

NOTE:

After installing a generic TCM into the vehicle and before the software flash has been performed, it is possible to illuminate the MIL and set a P0602 - TCM Not Programmed if the engine is started before the flash is completed. If DTC P0602 sets during programming, clear DTCs after the flash has completed.

  1. Using the scan tool and Dealer Connect, download the appropriate TCM flash file to the scan tool.
  2. Ignition on, engine not running.
  3. Vehicle in park with the brake pedal depressed.
  4. Following the menu on the scan tool, program the TCM.
  5. Perform the Neutral Learn Procedure.
  6. After the TCM has been programmed and the Neutral Learn Procedure is performed, a TCM Clear Self Learning Data procedure must be performed using the scan tool.
  7. Clear any stored DTCs.
  8. Road test the vehicle above 40 m.p.h. for at least two minutes.
  9. With the scan tool, select View DTCs in the TCM.
