Inhibitor Switch

INHIBITOR SWITCH

The inhibitor switch is installed in the control valve. TCM detects the range position based on the ON/OFF signal of each range output by the inhibitor switch, and performs various controls. The following list shows the inhibitor switch signal (INH1 4) and range position patterns.






If the range position is judged as P or N, TCM outputs the signal (PN signal) to permit starter drive. In R or D range, starter drive is inhibited to ensure safety.

In addition, if the position is judged as R range, TCM turns back lamp relay output to ON and turns the back lamp on.
