Reading DTCs Procedure

Connect the M-MDS(IDS) to the DLC-2.

After the vehicle is identified, select the following items from the initialization screen of the IDS.

Select "Self Test".
Select "Modules".
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.
  Snap shot data
- The snap shot data stores the currently detected DTC data.
- 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 both non-determination (1st diagnosis) and malfunction determination (2nd diagnosis) periods.

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.

RPM	RPM	Engine speed	RPM
VS	KPH {MPH}	Vehicle speed	VSS
SPARKADV	°	Ignition advance	-
IAT	°C {°F}	Intake air temperature	-

Verify the DTC according to the directions on the screen.
- If any DTCs are displayed, perform troubleshooting according to the corresponding DTC inspection. (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE .)
After completion of repairs, clear all DTCs stored in the TCM. (See CLEARING DTCS PROCEDURE .)
