Solenoid Reprogramming Procedure

Perform solenoid characterization reprogramming after one of the following service procedures:

NOTE:

Select "Replace Transmission" at the MCVM Characterization selection screen.

• Replace transmission assembly
NOTE:

Select "Replace Control Valve Solenoid Body" at the MCVM Characterization selection screen.

• Replace control valve solenoid body
NOTE:

Select "Replace Solenoid" at the MCVM Characterization selection screen.

• Replace solenoid (currently not an available Service Procedure)
NOTE:

Select "Refresh Characterization Data" at the MCVM Characterization selection screen.

• Replace TCM

To perform solenoid characterization after a transmission component replacement:

1. Document the new Transmission Unique Number (TUN)

   The TUN location may be found here: Transmission Identification Information . Since the TUN can be difficult to access when the transmission is installed in the vehicle, ensure you document the 16-digit TUN prior to installing the transmission in the vehicle.

2. Log into SPS.
3. Type the vehicle identification number (VIN).
4. Perform the SPS Transmission Control Module programming event.
   • Select "Transmission Control Module - Programming" to update TCM calibrations and Solenoid Characterization data.

     OR

   • Select "Transmission Control Module - MCVM Operations" to update Solenoid Characterization data only.
5. From the "MCVM (Mechanical Characterization and Virtual Matching) Operation Selection" screen, select the applicable service procedure to be performed. You will be prompted to provide the necessary Transmission Unique Number (TUN) or Part Unique Number (PUN) when replacing a transmission part.

At this point, the system will read the VIN from the Powertrain control module (PCM) using the multiple diagnostic interface (MDI) and then retrieve the applicable genealogy data tree from the cloud. This data tree accesses the original characterization data so that it may be updated with the new component information. The system acquires characterization data for the given TUN/PUN via the cloud and updates the genealogy tree. The PCM is updated with the correct solenoid characterization data, and the cloud is updated with the new genealogy relationship.
