Deviating speed signal from the wheel on the left-hand side of the front axle.
What causes Scania DTC 18?
The tyre in the circuit in question is the wrong dimension.
How does the system react?
If the circumference of a wheel is changed, the rotation speed of this wheel will deviate from that of the other wheels. As a result the ABS control cannot function normally. When the fault is active, the hill hold function ceases to function, if applicable
How to fix Scania ABS fault code 18?
