MEMORY FUNCTION [SJ6A-EL]

• 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.
End Of Sie

MALFUNCTION INDICATION FUNCTION [SJ6A-EL]

• 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]

• 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.

Condition
Detection condition
• Flash ROM (in TCM) internal circuit
malfunction is detected.
• Different numeric values for
EEPRROM and RAM (in TCM) are
detected.
• RAM (in TCM) read/write error is
detected.
• TR switch position voltage input to
TCM is less than 0.127 V when
ignition switch is at ON position.

or more, and no range signal is input
from the TR switch.
• Change in ATF temperature cannot be
detected for 10 min or more when
driving in D range.
• TCM detects ATF temperature of 200
°C {392 °F} or more.
