MALFUNCTION DETECTION FUNCTION [AW6A-EL, AW6AX-EL]

• In the malfunction detection function, the TCM detects malfunctions in the automatic transmission while driving.

• When vehicle driving conditions correspond with a preset malfunction detection condition, the TCM determines that the automatic transmission has a malfunction and stores the corresponding DTC.

• When a malfunction is detected, stored DTCs can be retrieved using the Mazda Modular Diagnostic System (M-MDS) connected to the DLC-2.

• When related systems or components have failed, the CM stores the DTC of the malfunctioning part in the CM memory, and allows for the retrieval of the store data using scanning tool when necessary. The DTCs are indicated using seven digits. Each digit indicates the following.

• 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.

• 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.
