Shift Interlock: Description and Operation

1. SHIFT LOCK MECHANISM
When the brake pedal is depressed with the ignition SW set at ON (The stop light SW is ON), the shift lock control ECU is activated, allowing the driver to change the shift lever to a position other than the P position.

2. REVERSE INHIBIT MECHANISM
Changing the shift lever to the R position is inhibited by operation of the shift lock control ECU and body ECU No. 2 while the vehicle is travelling forward.
If the vehicle speed is almost 0 kph, the signal is input to TERMINAL 8 of the shift lock control ECU through communication control of the body ECU and door ECU etc. allowing the driver to change the shift lever to the R position.

3. KEY INTERLOCK MECHANISM
When the ignition SW is turned to the ACC or ON position and the shift lever is at a position other than the P position, the shift lock control ECU is activated to flow the current into the key interlock solenoid. This inhibits to turn the ignition SW from the ACC position to the OFF position.
