1. Set the meter selector to the DC Voltage position.
2. Connect the red tester lead to the red/blue wire; then
connect the black tester lead to the black wire.
3. With the brake applied, the meter must show battery
voltage.
NOTE: If the meter shows no voltage, inspect the 10
amp ignition (IGN) fuse, brakelight switch, wiring har-
ness, or connectors.
Tilt Sensor
The tilt sensor is located beneath the driver’s seat.
WT565A
SUPPLY VOLTAGE
1. Disconnect the three-wire connector from the sensor;
then select DC Voltage on the multimeter and connect
the red tester lead to the orange wire and the black tes-
ter lead to the pink/black wire.
2. Turn the ignition switch to the ON position. The mul-
timeter should read battery voltage. If battery voltage
is not indicated, check the 30-amp fuse, wiring har-
ness, or the ignition switch.
3. Remove the red tester lead and connect to the blue/
brown wire. The multimeter should read approxi-
mately 0.2 DC volts. If the specified voltage is not
indicated, check wire connections at the ECM or sub-
stitute another ECM to verify the test.
OUTPUT VOLTAGE
NOTE: MaxiClips will be required on the multimeter
leads as the following tests are made with the sensor
connected.
1. Connect the three-wire plug to the sensor; then
remove the right-side mounting screw securing the
sensor to the frame.
2. Select DC Voltage on the multimeter.
3. Connect the red tester lead to the blue/brown wire and
the black tester lead to the pink/black wire; then turn
the ignition switch ON and observe the meter. The
meter should read 0.3-1.5 DC volts.
4. Tilt the sensor 60° or more to the left and right observ-
ing the meter. The meter should read 3.0-7.0 DC volts
after approximately one second in the tilted position.
If the meter readings are not as specified, the tilt sen-
sor is defective.
NOTE: When replacing the sensor after testing
make sure the arrow is directed up.
WC159A
Throttle Position Sensor
(TPS)
NOTE: Preliminary checks may be performed on this
component using the diagnostic mode on the LCD
gauge (see EFI Diagnostic System in this section).
TESTING
1. Remove the rear fenders and cargo box. Remove
the TPS connector plug from the TPS.
WT562A
NOTE: Prior to testing the TPS, inspect the three-
wire plug connector on the main harness and the
three-pin plug on the TPS for contamination, broken
pins, and/or corrosion.
! WARNING
Incorrect installation of the tilt sensor could cause sud-
den loss of engine power which could result in loss of
vehicle control resulting in injury or death.
CAUTION
Do not drop the tilt sensor as shock can damage the
internal mechanism.
