Freeze Frame Data
AUTOMATIC TRANSMISSION ON-BOARD DIAGNOSTIC FUNCTION [SJ6A-EL]
Freeze frame data (mode 2)
- 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 (mode 12)
- The data for DTCs currently detected is stored.
- The DTC recording timing 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.
