DTC Explanation Cause Reaction Action
System receiving no signals from
control potentiometer.
System receiving no signals from shift
control potentiometer.
Short-circuit or open-circuit in wiring/
starter motor relay.
Short-circuit or open-circuit in wiring/
main relay.
Short-circuit or open-circuit in Neutral
indication cabling. Bulb malfunction.
Open or short-circuit in cabling or in
reverse gear solenoid (actuator).
The system receives too high or too low
a boost pressure signal.
Faulty values from potentiometers,
controls not calibrated, communication
faults.
Faults in internal voltages in control
module.
Internal fault in control module.
Engine runs at constant 1000 rpm.

If the pressure is too high the system
will reduce the volume of fuel injected
until pressure has normalized (turbo
protection).

Check control potentiometer wiring and connec-
tions and connections to control position. Erase
DTC. Start the engine.
If the fault persists shifting can be carried out
directly on the reverse gear solenoids.
Check wiring/connections on shift control potenti-
ometer and connections to control position. Erase
DTC. Start the engine.
If the fault persists shifting can be carried out
directly on the reverse gear solenoids.
Check cabling and connections to starter relay in
terminal box. Check starter relay. Position 5 on the
location diagram, page 67. Erase DTC.
Check cabling and connections to main relay in
terminal box. Check main relay. Position 6 on the
location diagram, page 67. Erase DTC.
Check bulb in “Neutral” button. Check cabling and
connections to control position. Erase DTC.
Check reverse gear cabling and solenoids (actua-
tors). Erase DTC.
Check air cleaner. Check the pressure line from
the inlet manifold to the control module. Erase
DTC. Contact authorized workshop for inspection
of turbocharger (TC).
Check potentiometers, wiring and connections to
buttons on flying bridge panel. Recalibrate control
if necessary. Erase DTC.
Erase DTC. Contact authorized workshop.
Erase DTC. Recalibrate control.
Contact authorized workshop if recalibration
cannot be carried out.
