2.  After the vehicle is identified, select the following items from the initialization screen of the M-MDS.

•  When using the IDS (laptop PC)
1.  Select “DataLogger”.
2.  Select “Modules”.
3.  Select “TCM”.
•  When using the PDS (Pocket PC)
1.  Select “Module Tests”.
2.  Select “TCM”.
3.  Select “DataLogger”.

3.  Select the applicable PID from the PID table.

4.  Verify the PID data according to the directions on the screen.

Note
•  The PID data screen function is used for monitoring the calculated value of input/output signals in the module. Therefore, if the monitored value of the output parts is not within the specification, it is necessary to inspect the monitored value of input parts corresponding to the applicable output part control. In addition, because the system does not display an output part malfunction as an abnormality in the monitored value, it is necessary to inspect the output parts individually.

2.  After the vehicle is identified, select the following items from the initialization screen of the M-MDS.

•  When using the IDS (laptop PC)
1.  Select “DataLogger”.
2.  Select “Modules”.
3.  Select “TCM”.
•  When using the PDS (Pocket PC)

2.  Select “TCM”.
3.  Select “DataLogger”.

3.  Select the simulation items from the PID table.

4.  Perform the simulation function, inspect the operations for each parts.

•  If there is no operation sound from the solenoid after the simulation function inspection is performed, it is possible that there is an open or short circuit in the wiring harness, or solenoid, or sticking and operation malfunction.
