MALFUNCTION DETECTION FUNCTION [FS5A-EL]

id050221100300


Malfunction Detection Function

•  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.
