Trouble Code Type
Error Description Error at static plausibility check: absolute temperature difference of sensed temperature upstream SCR catalyst and ambient temperature > as static plausibility limit at engine cold start (engine was off for at least 8 h), temperature upstream of SCR catalyst is expected to be identical to ambient temperature =>
4360
2
SCR-Cat Temperature Plausibility Error
Error at dynamic plausibility check: temperature difference of sensed temperature upstream SCR catalyst and ambient temperature < as dynamic plausibility limit dynamic check is blocked if static plausibility check is already faulty => Temperature upstream SCR catalyst must be by 40°C higher than ambient temperature if engine runs and a certain delay time has expired
4361
3
DEF Error
DEF catalyst upstream temperature sensor: the voltage of sensor measured by ECU is out of the target range
4361
4
DEF Error
DEF catalyst upstream temperature sensor: the voltage of sensor measured by ECU is out of the target range
4365
3
Urea Tank/DEF Error
