AUTOMATIC TRANSAXLE - Transaxle Mechanism
START SAFETY MECHANISM
Inhibitor switch
The start safety mechanism ensures the safety
during the engine starting operation. When the
selector tever is in the position other than "P" or
"N", the electrical circuit for starting the engine is
kept in the OFF state by the inhibitor switch.
Therefore, the engine does not start even if the
ignition switch is turned to the "START" position.
located at the upper end of the manual control shaft
and is interlocked with the manual control lever. By
shifting the selector to the "P" or "N" range, the
electrical circuit inside the inhibitor switch is con-
nected to form the ignition circuit with which the
engine can be started. When the shift is in the "R"
range, the backup light lights up as the backup light
circuit is energized.
The inhibitor switch, in addition to the start safety
device, 'also includes a circuit for detection of the
selector lever position, for sending signals to the
transaxle control unit.
