Inspection Procedure

NOTE:

Perform the universal trip to clear permanent DTCs. Refer to DTC CHECK / CLEAR .

HINT:

Refer to inspection procedure for CAN communication system.
If the CAN communication malfunctions, the TCM cannot receive the current data from the ECM. In this case, the freeze frame data output from the TCM has not been updated, so the data will not be useful for the inspection. However, reading the Data List as the first step in troubleshooting is effective to find malfunctions.
The malfunction area can be checked using the Bus Check function on the Techstream. Refer to DIAGNOSIS SYSTEM .
