If EPAS is running for a long period, the EPAS control unit reduces its output so that the e / motor does not overheat.
If a malfunction occurs in the EPAS electrical circuit, the control unit goes into emergency mode, turning off the e / motor. At the same time, the corresponding K / L is switched on on the instrument panel. Information about the fault can be obtained through the diagnostic tool, because. the EPAS control unit is connected to the CAN bus.
To increase the torque transmitted to the steering shaft from the EPAS e / motor, a reduction gear is built into the steering column assembly.
