Throttle Release Switch; Brake Switch; Tether Switch - Polaris 850 MATRYX INDY XC 129 2021 Manual

THROTTLE RELEASE SWITCH

The throttle release switch is integrated into the right
hand throttle control block. The switch provides a
software stop signal to the ECU.
A software stop is used to determine the position of the
throttle release switch. The software stop system is
activated when the throttle release switch is closed
(closed throttle), but the TPS (throttle plate position) is
still above idle. When this occurs, the ECU will determine
the throttle cable is "stuck" and disable the ignition
system.
Test the switch at the handlebar connections connector.
