Scania fault code 259

Code 259 is used by 14 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 above the permitted level. Read explanation → TMS Transmission Management System Clutch actuator, clutch movement too small The gearbox control unit (TMS) has detected a difference in position as regards the position of the pushrod relative to the position of the clutch actuator. Read explanation → BMU Battery Management Unit Break, voltage class B from the propulsion battery The control unit has detected abnormal voltage values, indicating a break in the voltage class B from the propulsion battery. Read explanation → EMD Intake air mass flow sensor T126 The voltage in the circuit has been above the permitted level. Read explanation → EME Intake air mass flow sensor T126 The voltage in the circuit has been above the permitted level. Read explanation → EMO Intake air mass flow sensor T126 The voltage in the circuit has been above the permitted level. Read explanation → VDT Solenoid valve Unknown fault. Read explanation → ELC Electronically controlled air suspension Sensor signal from front axle level sensor. The voltage on the input from the level sensor is too high. Read explanation → ABS Anti-lock Braking System Brake pressure limitation The voltage from the EBL brake pressure sensor has been above the permitted level. Read explanation → ALM Secondary wake-up signal, short circuit The secondary wake-up signal is short-circuited to ground. Read explanation → WTA Water temperature sensor The water temperature rises too quickly. Read explanation → COMMUNICATOR Communicator (C200 / C300 / C400) No contact with the GSM antenna The fault code is activated when the connection between the control unit and GSM antenna U20 has been interrupted for more than 25 seconds. Read explanation → EACS Voltage class B The electric motor cannot run at the requested speed due to the RES control unit limiting the allowed current consumption. Read explanation → EQU Supply voltage 24 V The 24 V supply voltage is missing. Read explanation →
