PID/DATA MONITOR INSPECTION [SJ6A-EL]

2008 - MX-5 - Transmission/Transaxle

PID/DATA MONITOR INSPECTION [SJ6A-EL]

1. Connect the M-MDS to the DLC-2.

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

When using the IDS (laptop PC)

Select “DataLogger”.

Select “Modules”.

Select “TCM”.

When using the PDS (Pocket PC)

Select “Module Tests”.

Select “TCM”.

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.

Simulation Function Procedure

1. Connect the M-MDS to the DLC-2.

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

When using the IDS (laptop PC)

Select “DataLogger”.

Select “Modules”.

Select “TCM”.

When using the PDS (Pocket PC)

Select “Module Tests”.

Select “TCM”.

Select “DataLogger”.

3. Select the active command modes from the PID table.

4. Perform the active command modes, inspect the operations for each parts.

If the operation of output parts cannot be verified after the active command mode inspection is performed, this could indicate the possibility of an open or short circuit, sticking, or operation malfunction in the output parts.
