Taillight-Brakelight; Ignition Timing; Efi Diagnostic System - Arctic Cat ROV 2013 Service Manual

Taillight-Brakelight

VOLTAGE (Taillight)
NOTE: Perform this test at the socket end of the
taillight-brakelight harness (pigtail). The ignition
switch must be in the ON position and either high
beam or low beam selected on the light switch.
1. Set the meter selector to the DC Voltage position.
2. Connect the black tester lead to the black wire; then
connect the red tester lead to the white wire. The
meter should show battery voltage.
3. With the ignition key in the LIGHTS position, the
meter must show battery voltage.
NOTE: If battery voltage is not shown and the
headlights are illuminated, inspect the three-wire
connector in the left-rear canopy tube at the junc-
ture of the canopy tube and lower frame. If battery
voltage is shown on the meter, replace the bulb.
VOLTAGE (Brakelight)
NOTE: Perform this test at the socket end of the
taillight-brakelight harness (pigtail). The ignition
switch must be in the ON position.
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, wir-
ing harness, or connectors.

Ignition Timing

The ignition timing cannot be adjusted; however, verifying
ignition timing can aid in troubleshooting other components.
To verify ignition timing, use the following procedure.
NOTE: To check ignition timing, the seat, seat
back, and seat base must be removed.
1. Attach the Timing Light to the spark plug high ten-
sion lead; then remove the timing inspection plug
from the left-side crankcase cover.
2. Start the engine and using the RPM function on the
speedometer/tachometer, run at 1500 RPM; ignition
timing should be 10° BTDC.
3. Install the timing inspection plug.
If ignition timing cannot be verified, the rotor may be dam-
aged, the key may be sheared, the trigger coil bracket may
be bent or damaged, or the ECM may be faulty.

EFI Diagnostic System

DIGITAL GAUGE
The digital gauge can be used as a diagnostic tool for
many of the DTC's displayed. To place the gauge into the
diagnostic mode, use the following procedure.
1. Turn the ignition switch ON.
2. Depress and hold both Mode and Set buttons
together for approximately 10 seconds after which
the letters "dIAg" will appear on the LCD momen-
tarily followed by COOL.
NOTE: The display on the gauge will display in
SAE (speedometer in MPH mode) or Metric (speed-
ometer in km/h mode), For example to read tem-
perature in degrees Celsius, select km/h mode on
the gauge or to read Fahrenheit, select MPH mode.
3. Cycle the display by depressing either the Set or
Mode button to step to the desired function.
NOTE: The gauge can be utilized dynamically
(engine running/vehicle moving) or statically
(engine/vehicle stopped).
