TERMINAL LAYOUT
PHYSICAL VALUES
Fail-Safe
- If any malfunction occurs in the system and the control unit detects the malfunction, the EPS warning lamp in the combination meter turns ON to indicate system malfunction.
- When EPS warning lamp is ON, the system enters into a manual steering state. (turning force at steering wheel becomes heavy.)
- Under abnormal vehicle speed signal conditions, vehicle speed is judged as constant.
Protection Function
EPS control unit decreases the output signal to EPS motor during continuous extreme use of the power steering function (e.g., full steering) for protection of the EPS motor and EPS control unit (Overload protection control).
