The TCM can either receive data from the Engine Control Module or ABS control module, or it can send data to the ECM and ABSCM by using CAN communication. The CAN communicaton is one of the vehicle communications method, which is now widely used to transfer the vehicle data.
When the TCM judges that the CAN micro-computer , which is installed inside the TCM, is malfunctioning,the TCM sets this code.
Item | Detecting Condition | Possible Cause |
DTC Strategy | ● Check TCM | ● Faulty TCM |
Enable Conditions | ● IG switch on ● No actuator test ● No FAIL SAFE status of 3rd gear holding ● No FAIL in PG-A,B ● Power voltage ≥ 10V is detected for a series of 0.5 sec ● Engine STOP, | |
Threshold Value | ● CAN MI-COM communication fail | |
Diagnostic Time | ● 1sec | |
Fail Safe | ● INTELLIGENT SHIFT and is inhibited ● Learning for oil pressure control is inhibited ● Torque Retard requirement is inhibited. ● Direct connection control of TCC is inhibited. |
