Efi Diagnostic System - Arctic Cat Wildcar Trail Service Manual

 NOTE: If the vehicle is in warranty, removing or
adjusting the TPS will void warranty. If the TPS is
tested out of specification, the throttle body must be
replaced. If the vehicle is out of warranty, the TPS can
be adjusted.
2. Connect the TPS Multi-Analyzer Harness connec-
tor #8 to the TPS; then connect the harness to the
TPS Analyzer Tool.
3. Using a multimeter, connect the black tester lead to
the center socket (GND) on the analyzer and the red
tester lead to the white socket (VAR); then select the
DC Voltage position. The gauge should read 0.45-0.55
and at Wide-Open Throttle it should read up to
approximately 3.6.
 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 accelerator pedal to Wide
Open Throttle (WOT).
2. Place the ignition key in the ON position and wait for
10 seconds.
3. Release the accelerator pedal, and wait an additional
10 seconds.
4. Turn the key to the OFF position and allow the gauge
to shut off
