Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Transmission Fluid

Reconnect the battery and start the engine.
Locate the transmission dipstick (if equipped).
Remove the dipstick, wipe it clean, reinsert it, and then remove it again to check the fluid level.
If low, add the appropriate type of Toyota transmission fluid (e.g., Toyota WS fluid) to the fill line. If dirty or burnt, proceed to fluid change.

3. Inspect Transmission Linkage

Locate the transmission linkage and visually inspect for any disconnection or damage.
If damaged, replace the linkage or cable as necessary.
Ensure the linkage is properly connected to the transmission and the gear selector.

4. Test Brake Switch

Locate the brake switch near the brake pedal.
Use a multimeter to test for continuity when the brake pedal is pressed.
If the brake switch is faulty, replace it with a new one.

5. Check Fuses

Locate the fuse box, typically under the dashboard or in the engine compartment.
Refer to the fuse diagram to identify transmission-related fuses.
Replace any blown fuses with the same amperage rating.
