K: INHIBITOR SWITCH
The inhibitor switch assures safety when starting the engine. This switch is mounted on the right
side of the transmission case, and is operated by the selector lever.
When the selector lever is set to P or N, the electrical circuit in the inhibitor switch is closed and
the starter circuit is completed for cranking the engine.
When the selector lever is in the R, D, 3, 2 or 1 range, the electrical circuit in the inhibitor switch is
open. Hence engine cranking is disabled. In the R range, the backup light circuit is completed in
the switch, and the backup lights come on.
In addition to the above function, the inhibitor switch incorporates a circuit for detecting the select-
ed range position and sending the range signal to the TCM.
