1.  Connect the M-MDS to the DLC-2.

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

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

3.  Select the PID from the PID table

4.  Verify the PID data according to the directions on the M-MDS screen.

Note
•  Perform part inspection for the output device after PCM inspection.
•  The PID/DATA MONITOR function monitors the calculated value of the input/output signals in the PCM. Therefore, if a monitored value of an output device is out of specification, it is necessary to inspect the monitored value of the input device related to the output device control. Since an output device malfunction is not directly indicated as a malfunction of the monitored value for the output device, it is necessary to inspect the output device individually using methods such as the simulation function.

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

•  When using the IDS (laptop PC)
―  Select the “Toolbox” tab.
―  Select “DataLogger”.
―  Select “Modules”.
―  Select “PCM”.
•  When using the PDS (Pocket PC)
―  Select “Module Tests”.
―  Select “PCM”.
―  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.
