5. ON–VEHICLE INSPECTION
If a malfunction code is displayed during the DTC check, check the circuit listed for that code in the table
below and proceed to the appropriate page.
DTC No.Description of faultComment / Remedy
000No malfunction–
010
011Overvoltage shutoff
Undervoltage shutoffVoltage between 1 and 5 at connector A > 16 V
Voltage between 1 and 5 at connector A < 10.2 V
(Voltage values must be present > 20 seconds)
Check battery, regulator and electrical leads.
012OverheatingCheck temperature at temperature or overheating sensor >
125C.
Check water circuit.
014Possible overheating detected
(Hardware threshold value)Difference of measured values at temperature sensor > 15C
(min. 70C water temperature and metering pump in opera-
tion);
Check temperature sensor and overheating sensor, replace if
necessary.
017Overheating delected
(Hardware threshold value)Temperature at temperature or overheating sensor > 130C,
emergency OFF if DTC No. 012 or 014 not applicable;
Check water circuit, check temperature sensor and overheat-
ing sensor, replace if necessary.
020Glow plug breakCheck glow plug, replace if necessary.
021Glow plug output overloadCheck glow plug, replace if necessary.
030Combustion air blower motor
EMF outside perm. range.Blower impeller or burner motor fammed (frozen solid, dirty,
etc.)
Remedy jam, replace burner motor if necessary.
031Combustion air blower motor breakCheck lead to combustion air motor (burner motor) for continu-
ity, replace if necessary.
032Combustion air blower motor short–circuitCheck combustion air blower motor (burner motor), replace if
necessary.
Check supply lead (chafed, etc.).
047Metering pump short–circuitCheck supply lead to metering pump for short–circuit, check
metering pump, replace if necessary.
048Metering pump breakCheck supply lead to metering pump for continuity, remedy
break, replace metering pump if necessary.
051Cold blow time exceededAt start, if flame sensor above 70C > 240 sec.;
Check exhaust gas combustion air supply, check flame sen-
sor, replace if necessary.
052Safety time exceededWhen all perm. start attempts used up;
Check fuel delivery and fuel supply.
Check exhaust gas and combustion air ducts.
054Flame cutout, HIGH settingCheck fuel delivery and fuel supply.
Check exhaust gas and combustion air ducts.
056Flame cutout, LOW setting
Check exhaust gas and combustion air ducts.
If combustion OK → Check flame sensor, replace if neces-
sary.
060Temperature sensor breakCheck connecting leads.
Resistance value between 6 and 13 at connector B > 2 MΩ
If break)
061Temperature sensor short–circuitCheck connecting leads.
Resistance value between 6 and 13 at connector B < 2 MΩ
(If short–circuit)
