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

1.  Select "Self Test".

2.  Select "Modules".

3.  Select "TCM".

1.  Select "Module Tests".

2.  Select "TCM".

3.  Select "Self Test".

Note

•  Freeze frame data/snapshot data appears at the top of the help screen when the displayed DTC is selected.

Freeze frame data

―  The freeze frame data consists of data for vehicle and transaxle control system operation conditions when malfunctions in the transaxle control system are detected and stored in the TCM.

―  Freeze frame data is stored at the instant the malfunction indicator lamp illuminates, and only a part of the DTC data is stored.

Snapshot data

―  The snap shot data stores the currently detected DTC data.

―  The recording timing for the freeze frame data/snap shot data differs depending on the number of DTC drive cycles.

•  For a DTC with a drive cycle number 1, only the malfunction determination data is recorded.

•  For a DTC with a drive cycle number 2, both the malfunction determination and undetermined data is recorded.

3.  Verify the DTC according to the directions on the M-MDS screen.

Freeze frame data table

Note

•  Refer to PID monitor table for confirm the transaxle control system operation status while the TCM does not store the DTC. (See ON-BOARD DIAGNOSTIC SYSTEM PID/DATA MONITOR INSPECTION [FS5A-EL])

•  Freeze frame data items are not displayed, according to detected DTC.
