Throttle Release Switch (TRS)
TRS System Operation
This vehicle is equipped with a throttle release switch
(TRS) to detect when the throttle pedal has returned to the
rest position.
NOTE: The throttle pedal lever is designed to have a
few degrees of freeplay prior to engaging the throttle
arm that pulls the throttle cable.
With the pedal in the rest position, the "blade" at the top of
the pedal is almost out of the TRS switch slot, exposing the
TRS switch to magnetic force in the opposite side of the
sensor. When the pedal is depressed, the throttle pedal
blade blocks the magnetic force from the TRS switch.
TRS Location
The TRS switch (A) is located in the drivers foot control
area, mounted on the top of the throttle pedal assembly.
TRS Testing
The TRS is a serviceable item and can be tested using
Digital Wrench® or an Ohm meter.
1. Disconnect the TRS harness connection located by
the fuse box.
2. With the throttle pedal “at rest”, connect an
ohmmeter between the TRS pin terminals. A
resistance value of 2.15k Ohms +/- 5% at room
temperature should be obtained. If the sensor reading
is more than 2.26k Ohms, it is out of specification and
needs to be replaced.
3. With the throttle pedal fully depressed, connect an
ohmmeter between the TRS pin terminals. A
resistance value of 11.7k Ohms +/- 5% at room
temperature should be obtained. If the sensor reading
is less than 11.1k Ohms, it is out of specification and
needs to be replaced.
