Purpose, Function
The shift-lock system operates when the ignition is switched to ON and the brake pedal is not depressed, and inhibits the selector lever from being shifted from the P position to other positions.
If the shift-lock cannot be released by the normal operation, it can be released manually by inserting a flathead screwdriver into the shift-lock release hole (emergency manual shift-lock release system).

Operation
Shift-lock Release Conditions
The shift-lock is released when all of the following conditions are met (except shift-lock release system is operated manually).
Selector lever is in P position
Ignition is switched to ON
Brake pedal is depressed (brake light switch is on)
Shift-lock operation conditions (shift-lock release conditions not satisfied)
When the shift-lock release conditions are not met, the shift-lock operates.
Because there is no energization to the shift-lock solenoid at this time, the shift-lock solenoid is not energized.
As a result, the lock slider is positioned where it restricts the selector lever movement and the selector lever cannot be moved to any position other than P.

Shift-lock release (Shift-lock release conditions are satisfied)
When the shift-lock release conditions are met, the shift-lock does not operate.
At this time, the shift-lock solenoid is energized because there is energization to the shift-lock solenoid.
As a result, the selector lever can be moved to any position other than P by moving the lock slider to a position where it does not restrict the selector lever movement.

Emergency Manual shift-lock release system operation
The emergency manual shift-lock release system can be released manually even if the shift-lock release conditions are not met.
The lock slider restriction can be cancelled forcibly by pressing the shift-lock override button using a flathead screwdriver.
As a result, the selector lever can be moved to any position other than P.

Shift Lock System Inspection
Shift Pressure Control (Direct Electric Shift Control) [Fw6 A EL, Fw6 Ax EL]Ion Sensor
Purpose/Function
Detects ion generation in the combustion chamber for detecting pre-ignition.
Detects ions which occur due to fuel combustion as current by applying bias
voltage to the spark plug, which is amplified in the ignition coil internal
circuit and input to the PCM.

Heated Oxygen Sensor (HO2 S) Heater Control
Outline
Based on the control of the HO2S heater, a stabilized oxygen concentration
is detected even at low exhaust temperatures, and feedback control of fuel injection
even at cold engine start is made possible for improved cold temperature exhaust
emission performance.
