Code 6.1, PID/SPN 110. Coolant temperature
Reason:
•
Coolant temperature is too high.
Reaction:
•
Engine control unit reduces engine power (unless
the protection has been shut off with the VODIA
diagnostic tool).
Action:
•
Check the coolant level.
•
Check the charge air cooler (cleanliness).
•
Check if there is air in the cooling system.
•
Check the pressure cap on the expansion tank.
•
Check coolant temperature sensor function.
•
Check thermostat function.
Code 6.2, PID/SPN 105. Charge air temperature
Cause:
•
The charge air temperature is too high.
Reaction:
•
Engine control module reduces engine power (un-
less the protection has been shut off with the
VODIA diagnostic tool).
Remedy:
•
Check coolant level.
•
Check the charge air cooler (cleanliness).
•
Check charge air temperature sensor function.
•
Check thermostat function.

the CIU are not damaged.
Code 6.6, PID/SPN 100. Oil pressure
Reason:
•
Oil pressure is too low.
Reaction:
•
Engine control unit reduces engine power (unless
the protection has been shut off with the VODIA
diagnostic tool).
Action:
•
Check oil level.
•
Check that the oil filters are not blocked.
•
Check system pressure valves and safety valves
in the oil system.
•
Check oil pressure sensor function.
Code 6.9, PID/SPN 158
Battery voltage, CIU
Reason:
•
Short circuit to negative (-).
•
Faulty alternator.
•
Faulty battery, battery cables.
Reaction:
•
Engine start problems.
Action:
