Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a secure location and the engine is off.
Disconnect the battery to prevent accidental electrical issues.

2. Brake Light Switch Inspection

Locate the brake pedal switch above the brake pedal.
Inspect the switch for damage or misalignment.
If damaged, replace the brake pedal switch:
- Disconnect the wiring harness from the switch.
- Remove the mounting fastener and take out the switch.
- Install the new switch, ensuring it is aligned properly, and reconnect the wiring harness.

3. Shift Interlock Solenoid Check

Locate the shift interlock solenoid, usually near the gear shifter assembly.
Disconnect the electrical connector from the solenoid.
Test the solenoid for continuity using a multimeter.
If the solenoid is faulty, replace it.
- Remove any mounting screws and take out the solenoid.
- Install the new solenoid and reconnect the electrical connector.

4. Transmission Fluid Inspection

Check the transmission fluid level using the dipstick (if applicable).
If low, add the appropriate type of transmission fluid (Toyota ATF WS).
If the fluid is dirty or burnt, perform a transmission fluid change:
- Drain the old fluid and replace the filter if accessible.
- Refill with new fluid to the correct level.

5. Reassembly and Testing

Reconnect the battery.
Test the gear shift operation to ensure it moves out of Park.
Ensure that the brake lights function properly when the pedal is pressed.
