MALFUNCTION DETECTION FUNCTION
CHU050201026S03
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 WDS or equivalent connected to the
DLC-2.
