ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [EW6A-EL]

id050234290100


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.

(1)  Select “Self Test”.
(2)  Select “Modules”.
(3)  Select “TCM”.

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 data for all DTCs currently detected is stored.
Recorded DTC timing
―  For DTCs with one drive cycle, data is recorded during the malfunction determination period.
―  For DTCs with two drive cycles, data is recorded during non-determination (1st diagnosis) periods.

3.  Then, select the “Retrieve CMDTCs” and perform procedures according to the directions on the M-MDS screen.

4.  Verify the DTC according to the directions on the screen.

•  If any DTCs are displayed, perform troubleshooting according to the corresponding DTC inspection.

5.  After completion of repairs, clear all DTCs stored in the TCM. (See Freeze frame data item table.)


Freeze frame data item table

Note
•  Refer to PID/DATA 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 [EW6A-EL].)
•  Freeze frame data items are not displayed, according to detected DTC.
