DIAGNOSIS

No faults

Shutdown for overvoltage

Shutdown for undervoltage

Overheating (abnormal reference value)

Overheating (difference evaluation-1)

Overheating (abnormal heater operation)

Overheating (difference evaluation-2)

Overheating (defective hardware-2)

Open glow plug circuit

Overload or short circuit of glow plug

Short circuit of glow plug

Short circuit of communication line

Abnormal speed of combustion fan
motor

Defective combustion fan motor

Overload or short circuit of combus-
tion fan motor

Abnormal output of combustion fan
motor

Abnormal water pump operation

Overload or short circuit of water pump

Measure battery voltage (must be < 15.9V).
Check alternator and overvoltage.

Measure battery voltage (must be > 10.2V under load).
Check alternator, wiring and undervoltage.

Temperature at overheating sensor > 125°C: check cooling system.
Check temperature sensor and overheating sensor, replace if necessary.

Difference in temperature values between surface sensor and
control overheating sensor is too large. (Prerequisite for this
trouble code display is that the heater is in operation and the
water temperature at the overheating sensor has reached min.
80°C): check cooling system.
Check temperature sensor and overheating sensor, replace if
necessary

Heater does not operate (The controller is locked.)
Delete trouble code to release controller lock: check cooling system.
Check temperature sensor and overheating sensor, replace if nec-
essary

If the surface sensor has a far higher temperature value than the
control overheating sensor, then the system proceeds with a
fault shutdown.

Temperature at control overheating sensor > 130°C: check cool-
ing system. Check temperature sensor and overheating sensor,
replace if necessary.

Check plug cable for damage, replace if necessary

Check the communication line.

Defective fan wheel or combustion air fan motor (frozen,
contaminated, stiff, damaged cable)

Check cable harness for damage, replace if necessary.

Defective fan wheel or combustion air fan motor (contaminated, stiff)
Check cable harness for damage, replace if necessary.

Check the ground and short of combustion air fan motor circuit,
replace if necessary.

Check connector.

Check cable harness for damage, replace if necessary.

Check cable harness for damage, replace if necessary.
Check plug-in connection, replace if necessary.

Check cable harness for open to battery voltage, replace if necessary.

The controller is locked due to excessive starting problem.

During start (no flame formed yet), the flame sensor reports
temperature value too high for too long, check exhaust gas,
combustion air and flame sensor.

Check exhaust gas and combustion air.
Check fuel quantity and fuel supply.
Clean or replace filter in fuel pump.

Fault (no more starting attempt allowed ). Check exhaust gas
and combustion air system.
Check fuel quantity and fuel supply.
Check flame sensor - see trouble code 64 and 65.

Check cable harness for damage, check plug-in connection,
replace if necessary.
Check sensor resistance value, replace if necessary.

Check cable harness, replace if necessary.
Check sensor resistance value, replace if necessary.

Check cable harness for damage, check plug-in connection,
replace if necessary.
Check sensor resistance value, replace if necessary.

Check cable harness, replace if necessary.
Check sensor resistance value, replace if necessary.

Check cable harness for damage, check plug-in connection,
replace if necessary.
Check sensor resistance value, replace if necessary.

Check cable harness, replace if necessary.
Check sensor resistance value, replace if necessary.

Replace controller.

If too many resets occurs, replace controller
