CodeExplanation
Cause
Reaction
Action
Short-circuit or open-circuit in wiring.
Only Master unit transmits signal
Abnormal voltage on output to alpha
solenoid
Short-circuit or open-circuit in wiring
starter relay
Short-circuit or open-circuit in wiring main
relay
Short-circuit or open-circuit in wiring to
“Neutral” indication. Bulb malfunction
Abnormal voltage on output to compres-
sor
Short-circuit or open-circuit on wiring or in
the actuator (solenoid valves) on reverse
gear
The system has too high or too low value
on boost pressure
Fuel has too high temperature (> 70°C/
158°F)
Charge air temperature is too high
(> 80°C/176°F)
Abnormal voltage on output to fuel
temperature sender
Engine torque limited
If the pressure is too high the system will
reduce injected quantity of fuel until
pressure has normalized (turbo protec-
tion)
Volume compensation ceases – engine
power reduced
At too high intake air temperature the
system will reduce the injected fuel
quantity until temperature normalizes
(engine protection)
Fuel temperature is set to 60°C (140°F)
by the system
Check wiring and terminals to control position.
Erase diagnostic trouble code
Check wiring and terminal on injection pump.
Erase diagnostic trouble code. Start the engine.
Contact authorized workshop if fault persists
Check wiring and terminals to starter relay in
junction box. Check the starter relay. Erase
diagnostic trouble code
Check wiring and terminals to main relay in junction
box. Check main relay. Erase diagnostic trouble
code
Check bulb in “Neutral” button. Check wiring and
terminals up to control position. Erase diagnostic
trouble code
Check wiring and terminal on compressor. Erase
diagnostic trouble code. Start the engine.
Contact authorized workshop if fault persists
Check wiring to reverse gear and actuators on
reverse gear. Erase diagnostic trouble code
Check air cleaner. Check pressure line from inlet
manifold to control module. Erase diagnostic
trouble code. Contact authorized workshop to
check wastegate valve
Reduce fuel temperature. Erase diagnostic
trouble code. Check installation
Check charge air cooler and temperature in the
engine compartment. Erase diagnostic trouble
code. Check installation if the temperature in the
engine compartment is too high
Check wiring to the sender. Erase diagnostic
trouble code. Start the engine. Contact authorized
workshop if fault persists
