Solenoid Reprogramming Procedure

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

• Transmission assembly replacement - Document Transmission Unique Number (TUN) from service transmission and select "Replace Transmission" at the MCVM Characterization selection screen.
• Valve body assembly replacement - Document Part Unique Number (PUN) from service part and select "Replace Valve Body" at the MCVM Characterization selection screen.
• Line pressure control solenoid valve replacement - Document Part Unique Number (PUN) from service part and select "Replace Solenoid" at the MCVM Characterization selection screen.
• T6 power inverter module replacement, independently of the transmission assembly - Select "Refresh Characterization Data" at the MCVM Characterization selection screen.

To perform solenoid characterization after a transmission component replacement:

1. Document the new Transmission Unique Number (TUN) or Part Unique Number (PUN) as required. Refer to Transmission Identification Information .
2. Log into TIS2Web/SPS.
3. Type the vehicle identification number (VIN).
4. Select "T6 Power Inverter Module - MCVM Operations".
5. Select the applicable service procedure performed and provide the necessary TUN or PUN. At this point, the system will read the VIN from the engine control module (ECM) 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 hybrid/EV powertrain control module 1 is updated with the correct solenoid characterization data, and the cloud is updated with the new genealogy relationship.
