Freeze Frame PID Data Access Procedure
ON-BOARD DIAGNOSTIC TEST [L3 WITH TC]
Freeze Frame PID Data Access 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 "PCM".
- When using the PDS (Pocket PC)
- Select "Module Tests".
- Select "PCM".
- Select "Self Test".
3. Then, select the "Retrieve CMDTCs" and perform procedures according to directions on the M-MDS screen.
4. Retrieve the freeze frame PID data according to the directions on the M-MDS screen.
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 engine control system operation conditions when malfunctions in the engine control system are detected and stored in the PCM.
- 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 engine 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.
Freeze frame data table
NOTE:
- Refer to PID monitor table for confirm the engine control system operation status while the PCM does not store the DTC. Component Tests and General Diagnostics
- Freeze frame data items are not displayed, according to detected DTC.
