NOTE: Make sure that the ignition switch is in the
ON position, transmission in neutral, brake lock
released, and the engine stop switch in the RUN posi-
tion.
3. Depress the starter button while observing the meter.
The meter should drop to 0 volts and a “click” should
be heard from the relay.
NOTE: If a “click” is heard and more than 1 volt is
indicated by the meter, replace the starter relay. If no
“click” is heard and the meter continues to indicate
battery voltage, proceed to step 4.
4. Disconnect the two-wire plug from the starter relay;
then connect the red tester lead to the green wire and
the black tester lead to the yellow/green wire.

5. Depress the starter button and observe the meter.
NOTE: If battery voltage is indicated, replace the
starter relay. If no voltage is indicated, proceed to
Power Distribution Module (PDM) check in this sec-
tion.
Electronic Control Module
(ECM)
The electronic control module (ECM) is located beneath
the seat near the battery.
NOTE: The ECM is not a serviceable component. If
the unit is defective, it must be replaced.
The ECM is rarely the cause for electrical problems;
however, if the ECM is suspected, substitute another
ECM of the same part number to verify the suspected one
is defective.
Codes can be cleared by following the procedures located
in the EFI Diagnostic System in this section.
NOTE: If the throttle body, ECM, TPS, or ISC are
replaced, the EFI system must be synchronized. Use
the following procedure:
1. With the key off, depress throttle lever to Wide Open
Throttle (WOT).
2. Place the ignition key in the ON position and wait for
10 seconds.
3. Release the throttle lever and wait an additional 10
seconds.
4. Turn the key to the OFF position and allow the gauge
to shut off.
EFI Diagnostic System
LCD GAUGE
The LCD gauge can be used as a diagnostic tool for many
of the DTCs displayed. To place the gauge into the diag-
nostic 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 message “dIAg” will appear on the LCD gauge
momentarily followed by “COOL.”
EFI002A
NOTE: The display on the gauge will display in SAE
measurements (speedometer in MPH mode) or Metric
(speedometer in km/h mode), For example to read
temperature 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.
EFI004
NOTE: The gauge can be utilized dynamically
(engine running/vehicle moving) or statically
(engine/vehicle stopped).
Examples of Static checks: Battery voltage, fuel
gauge/sensor, and TPS (0% @ closed throttle, 95-100%
@ WOT).
Examples of Dynamic checks: Battery charging, coolant
temperature including fans ON/OFF, MAP/IAT, tachom-
eter, and speedometer signal.
