Fuel Feeding Process
Fuel Feeding job should be followed after changing FFH assy or after fuel line job.
[Notice]
Without feeding job, FFH system could make white
smoke with abnormal noise.
3. If the fuel is sprayed out, connect the fuel pipe to
FFH assembly and keep the engine running for
1 minute.
4. Connect the ambient temperature connector.
1. Disconnect the ambient temperature switch as
shown in picture (A).
2. Check if the fuel comes out after engine starting
as the FFH fuel supply hose is disconnected.

Controller Lock
• The controller is locked when the following faults occur:
Overheating
• If FFH overheats 10 times in succession, error code 015 appears and the controller is locked.
Too many start attempts
If FFH performs 10 start attempts in vain, error code 050 appears and the controller is locked.
8. TROUBLE DIAGNOSIS
1. FFH Heater Trouble Diagnosis Precedure
When Faults Occur, First Check…
• Faulty wiring?
(short circuits, interruptions)
• Visual check for
- corroded contacts
- defect fuses
- damaged electrical leads, links and connections
- damaged exhaust and combustion air guidance
• Check battery voltage
Battery voltage < 10 volt: the undervoltage protection has triggered
• Check fuel supply
Check Voltage Supply U
batt
(terminal 30)
Disconnect the 10-pin connector and measure the voltage present in connector between chamber 1 and chamber 2.
For deviations in the battery voltage, check the fuses, supply lines, ground connection and plus point on battery for loss
of voltage (corrosion / interruption).
Check Key-ON signal (D+)
Disconnect the 10-pin connector and measure the voltage present in connector 1 between chamber 6 and chamber 2.
[Notice]

• Measure battery voltage (must be < 15.9V)
• Check alternator
• Check alternator over voltage
• Measure battery voltage (must be > 10.2V under load)
• Check alternator
• Check lead
Temperature at overheating sensor >125°C
• Check cooling system:
• Check the temperature sensor and overheating sensor, replace
if necessary
Difference in temperature values between surface sensor and con-
trol overheating sensor is too large. (Prerequisite for this trouble
code display is that the heater is in operation and the water tem-
perature at the overheating sensor has reached min. 80°C)
• Check cooling system
• Check the temperature sensor and overheating sensor, replace
if necessary
The controller is locked.
• Delete the fault memory to release the controller
• Check cooling system
• Check the temperature sensor and overheating sensor, replace
if necessary
If the surface sensor has a far higher temperature value than the con-
trol overheating sensor, then the system proceeds with a fault shutdown.
Temperature at control overheating sensor > 125°C
• Check cooling system
• Check the temperature sensor and overheating sensor,replace
if necessary
• Check cable harness for this component for damage and
through current and replace component if necessary
• Check plug-in connection, replace component if necessary
• Check cable harness for this component for damage, replace
component if necessary
• Check cable harness for this component for damage, replace
component if necessary
• Check the line
