E5U050200000N01
• The OBD system has the following functions:
— Malfunction detection function: detects malfunctions of the input/output devices and system components of
the AT.
— Fail-safe function: controls the output device function and input value of the sensors/switches to ensure
minimum vehicle drivability when a failure is detected.
— Memory function: stores the DTC when a failure is detected.
— PID data monitoring function: monitors the input/output signal and calculated value of the TCM and sends
the monitoring data to the scan tool.
— Simulation function: Allows override operation of simulation items for input/output system parts preset in the
TCM.

MALFUNCTION DETECTION FUNCTION [SJ6A-EL]
E5U050200000N03
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.

MEMORY FUNCTION [SJ6A-EL]
E5U050200000N04
• The memory function stores malfunction information detected in the malfunction detection function. Once
malfunction 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 (malfunction information) can be cleared using the WDS or equivalent, or by disconnecting
the negative battery cable.

MALFUNCTION INDICATION FUNCTION [SJ6A-EL]
E5U050200000N05
• The malfunction indication function illuminates the MIL or AT warning light when the malfunction detection
function determines there is a malfunction.
End Of Sie
FAIL-SAFE FUNCTION [SJ6A-EL]
E5U050200000N06
• In the fail-safe function, minimum vehicle drivability is obtained by changing the signals that are determined to
be malfunctions by the malfunction detection function to the preset values, and limiting TCM control.
