Scania fault code 546

Code 546 is used by 13 different Scania systems. Choose the control unit shown in your diagnostic tool:

EMS Engine Management System Post injection ontime too long, cylinder 2. 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 Short circuit to ground on output for control unit E754. Read explanation → COO Coordinator Downhill speed control The voltage in the downhill speed control circuit has assumed an impermissible value. The voltage value does not correspond to a permitted switch position. Read explanation → MBS #Not implemented. Electrical error on CAN bus 5 The CAN-controller of CAN bus 5 has entered state bus-off, which indicates a communication error There is a short circuit on CAN bus 5. Read explanation → BCI Configuration fault, Expansion unit E 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 Implausible values measured by the motion sensor. Read explanation → CMS Unknown control unit An unknown control unit has been detected. Read explanation → ALM Micro switch upper storage compartment passenger side (truck)/micro switch A8 (bus), short circuit The micro switch is short-circuited to earth. Read explanation → APS Air Processing System Temperature sensor The internal temperature sensor is faulty or has given a value outside the permitted range. Read explanation → ACS Articulation Control System Proportional valve Short circuit to ground or overloading in the proportional valve circuit. Read explanation → EST Piston position sensor The fault code is activated when the CAN message from the piston position sensor is implausible or incorrect. Read explanation → ESTA Piston position sensor The fault code is activated when the CAN message from the piston position sensor is implausible or incorrect. Read explanation → ACSX Proportional valve Short circuit to ground or overloading in the proportional valve circuit. Read explanation →
