Deutz Engine Fault Codes Deutz Code Blink Code SPN FMI 524063 3 1558 869 SCR heater main relay; short circuit to Short-Circuit to battery on wiring to battery component Threshold 1 < SCRHtr_rUHtrMeasRatio_mp < Threshold 2 Check wiring, component 524063 4 1559 869 Connection between heating valve (Y31) Faulty wiring, faulty heater relay (K27-K31), on the control unit Pin A:92 and defective heating valve (Y31), Load side SCR heater main relay (K31) is a broken element in heating. short cut to ground. Threshold 1 < SCRHtr_rUHtrMeasRatio_mp < Threshold 2 Disconnect plug from heating valve (Y31) and reset fault. If fault is still present you have to look in the wiring of Y31 to the control unit Pin A:92. If error is no longer present, you have to check the wiring of Y31 via relay K31 and possibly the heating cables and relay (K27- K30). 524063 5 1555 869 Urea backflow line heater: broken wiring Open Load on wiring to component detected Threshold 1 < SCRHtr_rUHtrMeasRatio_mp < Threshold 2 Check wiring, component 524063 5 1556 869 Urea main relay: broken wiring detected relay defect Threshold 1 < relay not connected wiring harness broken SCRHtr_rUHtrMeasRatio_mp < Threshold problems with supply voltage 2 Check wiring, component 524063 5 1557 869 Urea pressure line heater: broken wiring Open load on wiring to component detected Threshold 1 < SCRHtr_rUHtrMeasRatio_mp < Threshold 2 Check wiring, component 524063 5 1560 869 SCR relay for suction line not connected relay defect Threshold 1 < relay not connected wiring harness broken SCRHtr_rUHtrMeasRatio_mp < Threshold problems with supply voltage 2 Check wiring, component 524063 5 1561 869 Open load on wiring to component Open load on wiring to component Threshold 1 < SCRHtr_rUHtrMeasRatio_mp < Threshold 2 Check wiring, component 524063 5 1562 869 SCR heater tank; open load Check wiring, component 3121671 Description Possible Cause Open load on wiring to component Action 3-199
