MULTI-MODE MANUAL TRANSAXLE SYSTEM Shift Lock Solenoid Circuit

DESCRIPTION

The shift lock solenoid is built into the shift lock control unit assembly. When the ignition switch is turned off, or when the shift lever is in the N position without depressing the brake pedal although the ignition switch is turned to ON, the shift lock solenoid restricts the shift lever movement.

The transmission control ECU sends the shift lock cancellation signal to the shift lock solenoid to cancel the shift lock when the multi-mode manual transaxle system conditions are satisfied.
