Nissan Rogue Service Manual: ECU diagnosis information
EPS CONTROL UNIT
Reference Value
VALUES ON THE DIAGNOSIS TOOL
CAUTION: The output signal indicates the EPS control unit calculation data. The normal values will be displayed even in the event that the output circuit (harness) is open.
NOTE: The following table includes information (items) inapplicable to this vehicle. For information (items) applicable to this vehicle, refer to CONSULT display items.
*1: Almost in accordance with the value of “MOTOR SIG”. It is not a
malfunction though these values are not
accorded when steering quickly.
*2: Normally displays 100%. In case of an excessive stationary steering, the
assist curvature gradually falls.
However, it returns to 100% when left standing.
*3: It is not a malfunction, though it might not be corresponding just after
ignition switch in turned ON
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).

Active engine brake
The Active Engine Brake function adds subtle
deceleration by controlling CVT gear ratio, depending
on the cornering condition calculated
from driver’s steering input and plural sensors.
This benefit is for easier traceability and less
workload of adjusting speed with braking at corners.
