MEANING OF THE FAULT
CODE
Possible reason for fault
detection
Reaction of the
TCU
Possible steps
to repair
Remarks
ENGINE TORQUE OR
ENGINE POWER
OVERLOAD
TCU calculates an engine
torque or engine power
above the defined
thresholds
OP-Mode: normal
TRANSMISSION OUTPUT
TORQUE OVERLOAD
TCU calculates an
transmission output torque
above the defined
threshold
OP-Mode: normal
TRANSMISSION INPUT
TORQUE OVERLOAD
TCU calculates an
transmission input
torque above the defined
threshold
Programmable :No
reaction or shift to
neutral
OP-Mode: normal
S.C. TO GROUND AT
JOYSTICK STATUS
INDICATOR
TCU detected a wrong
voltage at the output pin,
that looks like a s.c. to
vehicle ground
Cable is defective and is
contacted to vehicle
ground
Joystick status indicator
has an internal defect
Connector pin is contacted
to vehicle ground
No reaction
OP-Mode: normal
Check the cable from
TCU to joystick status
indicator
Check the connectors
from joystick status
indicator to TCU
Check the resistance

of joystick status
indicator
OVERTEMP CONVERTER
OUTPUT
TCU measured a oil tempe-
rature at the converter
ouput that is over the
allowed threshold.
