Section 04 FUEL SYSTEM
Subsection 02 (FUEL TANK AND FUEL PUMP)
The information center interprets this signal and
turns on the appropriate number of segments of
a bar type fuel level indication in the lower RH side
of the digital screen in the information center.

Use the BRP diagnostic software (BUDS2) to
check for a fault code. Refer to
DIAGNOSTIC
AND FAULT CODES
.
Testing Fuel Level Sensor Voltage
1. First ensure battery is fully charged.
2. From under the steering support area, discon-
nect the 20-pin connector.

3. Connect the D IAGNOSTIC HARNESS (P/N 529 036

to make an in-line connection between the
disconnected connector.

NOTE: Voltage could be slightly different depend-
ing on battery voltage but should remain relatively
close to this range. If fuel tank is not full or empty,
the voltage value will be proportional to the fuel
level (somewhere in-between).
If voltage is as per specifications the fuel level cir-
cuit and sensor are good. If fuel level does not
work in information center, try a new one.
