Backup Lamp Switch: Description and Operation
OPERATION
With transaxle in REVERSE the Back/Upshift Switch allows current flow to illuminate backup lamps. The Switch/Sensor incorporates a series of
step down resistors which corresponds to the position of the manual lever. This sensor also houses the START circuits for the ignition system to
allow the vehicle to be started in PARK or NEUTRAL. The BACKUP lamp circuits, which are closed in reverse, are also contained within this
sensor.
