MALFUNCTION DETECTION FUNCTION [JA5AX-EL]

id050206100300

## Failure Detection Function

• In the failure detection function, the TCM detects malfunctions in the automatic transaxle while driving.
• When vehicle driving conditions correspond with a preset failure detection condition, the TCM determines that the automatic transaxle has a malfunction and stores the corresponding DTC.
• When a malfunction is detected, stored DTCs can be retrieved using the WDS connected to the DLC-2.

## Memory Function

• The memory function stores failure information detected in the failure detection function. Once failure information is stored, the memory will not be cleared even when the ignition switch is turned off (LOCK position) or the malfunction is repaired.
• The stored memory (failure information) can be cleared by using the WDS or disconnecting the negative battery cable.

## Failure Indication Function

• The failure indication function illuminates the AT warning lights when the failure detection function determines there is a malfunction.
