Fault
Code
(hex)
MEANING OF THE FAULT
CODE
Possible reason for fault
detection
Reaction of the
TCU
Possible steps
to repair
Remarks
S.C. TO GROUND AT DLM
TRANSVERSAL OUTPUT
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
Device has an internal
defect
Connector pin is contacted
to vehicle
ground
Output will be on until
TCU power down even
if fault vanishes (loose
connection)
OP-Mode: normal
Check the cable
from TCU to the valve
Check the connectors
Check the resistance
of valve
O.C. AT CLUTCH KR
the measured resistance
value of the valve is out of
limit.
cable / connector is
defective and has no
contact to TCU
regulator has an internal
defect
TCU shifts to neutral
OP-Mode: limp home
if failure at another
clutch is pending
TCU shifts to neutral
OP-Mode: TCU
shutdown

check the cable from
TCU to the gearbox
check the connectors
from gearbox to TCU
check the regulator
resistance
1)
check internal wire
harness of the
gearbox
S.C. TO BATTERY
VOLTAGE AT DLM
TRANSVERSAL OUTPUT
TCU detected a wrong
voltage at the output pin,
that looks like a s.c. to
battery voltage
Cable is defective and is
contacted to battery
voltage
Device has an internal
defect
Connector pin is contacted
to battery voltage
No reaction
OP-Mode: normal
Check the cable
from TCU to the valve
Check the connectors
Check the resistance
of valve
