MID 130 PSID 232 Powertrain CAN

The document provides fault codes for a transmission control unit, including descriptions of possible faults, fault conditions, potential symptoms, and possible causes. Specifically: FMI 2 and FMI 9 faults relate to issues with CAN 2 data communication between the TCM and engine, which could result in a yellow check engine light and slow gear shifts. An FMI 3 fault on the DIEE signal involves the voltage level being too high, which may cause a yellow check engine light, cranking to be inhibited, the engine unable to start, and all non-programming communication with the control module to be disabled. The document provides technical transmission fault code information to aid in diagnosing potential powertrain communication and electrical issues.
