ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [AW6A-EL, AW6AX-EL]

Reading DTCs 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 "Self Test".
- Select "Modules".
- Select "TCM".

- When using the PDS (Pocket PC)

- Select "Module Tests".
- Select "TCM".
- 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.
- For the freeze frame data, if there are several malfunctions in the transaxle control system, the data for the malfunction which occurred initially is stored. Thereafter, if a misfire or fuel injection control malfunction occurs, data from the misfire or fuel injection control malfunction is written over the initially stored data. However, if the initially stored freeze frame data is a misfire or fuel injection control malfunction, it is not overwritten.

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