Volvo DTC TCM-0A31

Make:VolvoCode:TCM-0A31Definition:Control Module Communication (Signal Missing From ECM) AW55-50/51SN TransmissionDescription:The engine control module (ECM) puts a signal about the present torque on the control area network (CAN). The transmission control module (TCM) uses the signal to determine shift points and to adjust system pressure in the transmission. The diagnostic trouble code (DTC) is stored if the control module detects that: There is no torque signal from the engine control module (ECM) or the signal is faulty. The diagnostic trouble code (DTC) can be diagnosed with ignition on and when the CAN network is OK. General warning lamp lit.Cause:

• Fault-trace the central electronic module (CEM).
• Locate the cause of the fault in the engine control module (ECM).
• Intermittent open circuit or short-circuit on the CAN lead between the engine control module (ECM) and the transmission control module (TCM).
