MEMORY FUNCTION [SJ6A-EL]
EHU050200000104
•
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]
EHU050200000105
•
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]
EHU050200000106
•
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.

P0601
Flash ROM malfunction
•
Flash ROM (in TCM) internal circuit
malfunction is detected.
•
Emergency mode
•
Inhibits self learning control
•
Inhibits driver adaptive shift control
•
Inhibits TCC control
•
Inhibits slip control
P0603
EEPROM malfunction
•
Different numeric values for
EEPRROM and RAM (in TCM) are
detected.
N/A
P0604
RAM malfunction
•
RAM (in TCM) read/write error is
detected.
•
Emergency mode
•
Inhibits self learning control
•
Inhibits driver adaptive shift control
•
Inhibits TCC control
•
Inhibits slip control
P0707
Transmission range (TR)
switch circuit low input
(short to ground)
•
TR switch position voltage input to
TCM is less than 0.127 V when
ignition switch is at ON position.
•
D range is determined when there is no
TR switch signal input.
•
Inhibits slope mode control
P0708
Transmission range (TR)
switch circuit high input
(open circuit)
•
Vehicle speed is 30 km/h {18.6 mph}
or more, and no range signal is input
from the TR switch.
•
D range is determined when there is no
TR switch signal input.
•
Inhibits slope mode control
P0711
