Scania fault code 545

Code 545 is used by 12 different Scania systems. Choose the control unit shown in your diagnostic tool:

EMS Engine Management System Post injection ontime too long, cylinder 1. The error is detected when the post injection ontime, for either post1 or post2, has been consequtively too long for a period of time. Read explanation → VDT Output signal Invalid configuration. Read explanation → COO Coordinator Downhill speed control The voltage in the downhill speed control switch has been above the permitted level. Read explanation → MBS Brown CAN bus, no communication The MBS control unit fails to detect communication on the brown CAN bus within the set time period. Read explanation → CUV Visibility system Dip switch for main/dipped beam The control unit input for main/dipped beam changeover has been short circuited to ground for more than 120 seconds. Read explanation → BCI Configuration fault, Expansion unit D The expansion unit is responding, but does not exist according to the vehicle configuration. Read explanation → LAS Locking and Alarm System Motion sensor in the cab The motion sensor has detected a fault in the LIN bus. Read explanation → ICL Instrument Cluster External instrument lighting Output PWM1 (external instrument panel lighting) for the instrument cluster has an unknown fault, is short circuited to voltage or is overloaded. The instrument cluster indicates l… Read explanation → CMS Suspension management system The CMS control unit interprets the suspension management system control unit as incorrectly configured. The chassis serial number in the CMS control unit differs from the one in t… Read explanation → ALM Micro switch upper storage compartment passenger side (truck)/micro switch A8 (bus), short circuit The micro switch is short-circuited to the voltage supply. Read explanation → ACS Articulation Control System Proportional valve Short circuit to supply voltage in the proportional valve circuit. Read explanation → ACSX Proportional valve Short circuit to supply voltage in the proportional valve circuit. Read explanation →
