When the TCM cannot read the data from the ECM through the CAN-BUS line, the TCM sets this code.
CAN-BUS circuit malfunctioning or ECM can be a posssible cause of this DTC.
Item | Detecting Condition & Fail Safe | Possible Cause |
DTC Strategy | ● Check voltage range | ● Open or Short in CAN communication harness. ● Faulty ECM. ● 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 | ● In case of no ECU information | |
Diagnostic Time | ● 1.5 Sec. | |
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 |
