MALFUNCTION DETECTION FUNCTION[LA4AX-EL (CD4E)]


id050207100300


Malfunction Detection Function

•  In the malfunction detection function, the PCM detects malfunctions in the automatic transmission while driving.
•  When vehicle driving conditions correspond with a preset malfunction detection condition, the PCM 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.
