Code 258 is used by 12 different Scania systems. Choose the control unit shown in your diagnostic tool:

EMS Engine Management System Mass flow sensor The voltage in the circuit has been below the permitted level. Read explanation → TMS Transmission Management System Clutch actuator, incorrect clutch position The transmission management system, TMS, has detected that the clutch position requested from the clutch actuator, ECA, does not match the expected position. Read explanation → BMU Battery Management Unit TMS control unit has no CAN message There is no CAN message from the propulsion batteries to the TMS control unit. Read explanation → EMD Intake air mass flow sensor T126 The voltage in the circuit has been below the permitted level. Read explanation → EME Intake air mass flow sensor T126 The voltage in the circuit has been below the permitted level. Read explanation → EMO Intake air mass flow sensor T126 The voltage in the circuit has been below the permitted level. Read explanation → VDT Solenoid valve Short circuit to battery. Read explanation → ELC Electronically controlled air suspension Sensor signal from front axle level sensor. The voltage on the input from the level sensor is outside the valid range (2.97V-5.25V). Read explanation → DDU DDU overheating fault Detection is performed by an internal sensor measuring SoCs temperature Read explanation → COMMUNICATOR Communicator (C200 / C300 / C400) The SIM card not locked in the holder There is no signal when the SIM card holder lock is in the lock position. Read explanation → EACS Voltage class B The voltage class B is too low and the electric motor cannot run at the requested speed. Read explanation → EQU Supply voltage 12 V The 12 V supply voltage is missing. Read explanation →
