ON-BOARD DIAGNOSTIC SYSTEM MALFUNCTION DETECTION FUNCTION [PCM (FN4A-EL)]

• In the malfunction detection function, the PCM detects malfunctions in the transaxle while driving.

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

• When a malfunction is detected, stored DTCs can be retrieved using the scan tool 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.

• On-board diagnosis is performed using the flow pre-set in the PCM, and according to the test execute command sent to the PCM from the external tester.

• If a malfunction is detected as a result of the on-board diagnosis, a DTC is recorded in the PCM.

• Refer to the self test table for DTCs corresponding to the self test function.

• 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.

• 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.
