ON-BOARD DIAGNOSTIC SYSTEM MALFUNCTION DETECTION FUNCTION [DJVA-EL]

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

• When vehicle driving conditions correspond with a preset malfunction detection condition, the TCM 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.

• The drive cycle is the period from the time the engine is started to being stopped. One drive cycle indicates the period from the time the engine is started and stopped one time. If this period is repeated twice it then becomes 2 drive cycles.

• The drive cycles are the DTC and pending code recording/clearing, and the AT warning light illumination on/off conditions.

• The pending code is a temporary DTC detected.

• If the malfunction is repaired after being detected and the engine is started, the pending code is cleared.

• The snap shot data stores the currently detected DTC data.

• The recording timing for the snap shot data differs depending on the number of DTC drive cycles.
