Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Apply the parking brake for safety.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the fluid level.
If low, add the correct type of transmission fluid (Toyota ATF WS) to the fill level.
If the fluid is dark or has a burnt smell, consider a fluid change.

3. Inspect Shift Linkage

Remove the center console cover to access the shift linkage.
Inspect the linkage for any loose or damaged components.
Tighten any loose bolts and replace damaged parts as necessary.
Reassemble the center console after inspection.

4. Test Brake Light Function

Have an assistant press the brake pedal while you observe the brake lights.
If the brake lights do not illuminate, check the brake light switch and wiring.
Replace the faulty brake light switch if necessary.

5. Check Transmission Control Module

Locate the TCM (usually near the transmission or under the dashboard).
Inspect all connectors for corrosion or damage.
If necessary, reset the TCM by disconnecting the battery for a few minutes and reconnecting it.
