Section 04 FUEL SYSTEM
Subsection 01 (INTELLIGENT THROTTLE CONTROL (iTC))
NOTE: The above stated voltages vary slightly de-
pending on the actual voltage applied to the circuit
and the current flow through the diodes. When
using a Fluke 115 multimeter for testing in diode
test mode, the voltage and current applied by the
multimeter are lower than in circuit. The quality
of probe contact, the actual probes and leads, and
the precision of the meter calibration will all affect
the results, which will most likely be slightly lower
than nominal values stated.
Testing the Mode/Speed Control
Switch
If Mode/Speed Control switches do not allow the
selection, test the switches as follows:
– Connect the vehicle to the BRP diagnostic soft-
ware (BUDS2). Refer to
COMMUNICATION
TOOLS
subsection.
– Check if there is any occurred or active fault
code(s). If not, proceed with the following test.
– InBUDS2,goto:
• Measurements page
• Cluster button
• Cluster - Basic tab
– Depress the Mode button on steering and
check the Mode light status.
– Repeat with the Speed Control switch. Speed
Control light status should change
If one switch does not function, replace
Mode/Speed Control switch.
If both switches stay off, do the following to verify
the circuit.
1. Remove the gauge support cover.
2. Disconnect the gauge connector.
3. Using the multimeter set to the diode test func-
tion, test the Sport or ECO switches as per fol-
lowing tables.
REQUIRED TOOL
FLUKE
115 MULTIMETER (P/N 529 035 868)
NOTE: In diode test mode, the multimeter will
test the voltage drop through the diodes.

OL
NOTE: Remember that each diode should drop
approximately 0.6 Vdc when positively biassed,
and read as an OL (open circuit) when negatively
biassed (leads reversed).
If, when measuring between pins 14 and 15 an
OL is obtained with both positive and negative
diode biassing, test the wiring harness continu-
ity between the gauge and switch assembly. If
harness continuity is good, replace the switch
assembly.
If any reading is significantly different than listed,
carry out the same test at the switch connector,
refer to the wiring diagram. If you obtain the same
results, replace the switch as sembly.
