Arctic Cat HDX 500 2017, Service Manual

Page: 152 / 190

151
Usage: Verify TPS signal and adjust throttle cable.
Fuel Sensor (FUEL)
WT545
Display: Fuel level signal from the fuel level sensor.
DTC: C1400, C1401, C1402
Usage: Check output of the fuel level sensor.*
1. Full fuel is indicated by a reading of 0-5 ohms.
2. Empty is indicated by a reading of 95-105 ohms.
* 110-500 ohms, suspect the fuel level sensor or wiring. 0-100 ohms but
no gauge indication, suspect the gauge.
Tachometer (RPM)
WT544
Display: Engine RPM
DTC: P0336, P0337, P0339
Usage: Verify engine speed signal from the following.
1. CKP (crankshaft position) sensor to ECM
2. ECM (CAN) signal to gauge (tachometer)
3. ECM (CAN) signal to EPS
Speedometer (SPEED)
WT543
Display: Vehicle speed signal.
DTC: P0500
Usage: Verify speedometer sensor signal from the fol-
lowing.
1. Speed sensor to ECM.
2. ECM (CAN) signal to gauge (speedometer/odometer).
3. ECM (CAN) signal to EPS
DIAGNOSTIC TROUBLE CODES (DTC)
If an EFI or related chassis component fails or an out-of-
tolerance signal is detected by the ECM, a diagnostic
trouble code (DTC) will be generated in the ECM and
displayed on the LCD. The DTC will be displayed alter-
nately with a wrench icon or malfunction indicator light
(MIL). The DTC will continue to flash, until the mal-
function is corrected and the code cleared.
Code List
 NOTE: Each of the following numerical codes will
have a one-letter prefix of C, P, or U. A “C” prefix
denotes a chassis malfunction, a “P” prefix denotes a
power train malfunction, and a “U” prefix denotes a
loss of communication with the gauge.
 NOTE: Normal malfunction codes are cleared from
the LCD when the component is replaced or the mal-
function is corrected; however, intermittent codes
must be cleared as noted in the code chart.
