3. Turn the ignition switch to the ON position.
4. The meter must show approximately 6 DC volts.
5. Leave the black tester lead connected; then connect
the red tester lead to the signal lead pin (S).
6. Slowly move the vehicle forward or backward; the
meter must show 0 and approximately 6 DC volts
alternately.
NOTE: If the sensor tests are within specifica-
tions, the LCD gauge must be replaced (see Steer-
ing/Frame/Controls section).
To replace a speed sensor, use the following procedure.
1. Disconnect the three-wire connector from the speed
sensor harness or from the speed sensor; then remove
the Allen-head cap screw securing the sensor to the
sensor housing.
2. Remove the sensor from the sensor housing account-
ing for an O-ring.

3. Install the new speed sensor into the housing with
new O-ring lightly coated with multi-purpose grease;
then secure the sensor with the Allen-head cap screw
(threads coated with blue Loctite #242). Tighten
securely.

Electronic Power
Steering (EPS)
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-sensing
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.
The following is a list of conditions that can generate a
code.
NOTE: The EPS assembly is not serviceable and
must not be disassembled or EPS warranty will be
voided. Make sure to thoroughly troubleshoot the
entire system before replacing the EPS assembly.

C1306 System Volt-
age Low
System voltage low (less
than 11 V DC at EPS). Wire
harness issue, faulty volt-
age regulator, weak battery,
or loose battery terminals.
EPS will auto-recover
when battery supply
returns to normal
C1307 System Volt-
age High
System voltage is high
(more than 16 V DC at
EPS). Wire harness issue,
faulty voltage regulator, or
loose battery terminals.
EPS will auto-recover
when the battery sup-
ply returns to normal
C1308 Temp Above
110° C
Clean EPS housing and
cooling fins.
EPS will auto-recover
when internal temp
drops below 150° C
C1309 Temp Above
120° C
Clean EPS housing and
cooling fins.
EPS will auto-recover
when internal temp
drops below 115° C
C1312 Vehicle
Speed
Broken CAN wires in main
harness, disconnected or
defective speed-sensor,
broken speed sensor wires.
EPS will auto-recover
when vehicle speed
signal returns to nor-
mal
