Transmission Control Module (TCM) - FNR5 Transaxle

The TCM (if equipped) uses the high speed CAN for communication with the diagnostic tool and other modules on the high speed CAN. The TCM controls transaxle shifting, the electronic pressure control solenoid, and the torque converter clutch.

Check the high speed CAN circuits between the TCM C2352b and the DLC C251. The total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the high speed CAN, damage to the DLC C251, damage to the TCM C2352b, or a problem in the in-line connector.
