Rpm Limiter; Electronic Power Steering (Eps) - Arctic Cat PROWLER HDX 2015 Service Manual

RPM Limiter

Component data can be retrieved using the CATT II. Uti-
lize the Sensor Data screen.

NOTE: The ROV is equipped with an ECM that cuts fuel spray and spark when maximum RPM is approached.
When the RPM limiter is activated, it could be misinterpreted as a high-speed misfire.

Component data and system updates can be retrieved/
performed using the CATT II. Navigate the screens as
required.
Certain models were produced with electronic power steer-
ing. The EPS system is an electro-mechanical device that
utilizes 12 volt DC power to drive a motor linked to the
steering shaft to assist the driver when rotating the steering
wheel. Driver steering inputs are detected by a torque-sens-
ing transducer assembly within the EPS housing. These
inputs are converted to electronic signals by the transducer
and control circuitry to tell the motor which way to drive the
steering shaft. When no steering input (pressure on the
steering wheel) is detected, no torque signal is generated,
and no steering assist is provided by the motor.

The EPS system is battery-system powered; therefore, the
battery must be in good condition and fully charged.
Power delivery and overload protection are provided by an
EPS relay and 30-amp fuse, located under the seat in the
Power Distribution Module (PDM).
If a system malfunction occurs, a diagnostic trouble code
(DTC) will be displayed on the LCD gauge. Initially, the
gauge will go blank for 30 seconds and the code will flash;
then the gauge will return to normal except the code will
continue to be displayed.

Internal EPS Condition
System voltage low (less than 11 VDC at the
EPS). Wire harness issue, faulty voltage regu-

System voltage high (more than 16 VDC at
the EPS). Wire harness issue, faulty voltage
regulator or loose battery terminals.
