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
