What does Scania CUV fault code 56 mean?
Open circuit or too low current consumption in circuit. The fault code can also be set when there is too high current consumption in the circuit, caused by short circuiting.
What causes Scania DTC 56?
The cause can be a defective lamp, incorrect type of lamp or open circuit in the wiring.
How does the system react?
The control unit constantly monitors the current consumption on the output when the output is active. If the current consumption is too low, a fault code is registered. The fault code is only found on control unit versions with assembly part number 1482564, 1540437, 1527199 and 1729485. If a fault is detected in the main beam circuit (right main beam), dipped beam will be switched on instead. The lights adjustment motor will then adjust the headlamp downwards as far as it will go due to internal connection between the dipped beam and the lights adjustment motor.
How to fix Scania CUV fault code 56?
Check the lamp and its switch and possible open circuit in the wiring.
