Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid electrical shorts during the process.

2. Check Transmission Fluid

Remove the transmission dipstick (if applicable) and wipe it clean.
Insert the dipstick back into the tube and remove it again to check the fluid level.
If low, add the recommended transmission fluid (Toyota ATF WS) until the proper level is reached.

3. Inspect Brake Pedal Switch

Locate the brake pedal switch, usually mounted on the brake pedal assembly.
Disconnect the electrical connector and use a multimeter to check for continuity when the pedal is pressed.
If defective, replace the brake pedal switch.

4. Examine Transmission Linkage

Raise the vehicle using jack stands for safety, ensuring it is securely supported.
Inspect the transmission linkage for any signs of wear or disconnection.
Tighten or reattach any loose components, replacing worn linkage if necessary.

5. Test and Replace Transmission Control Module (if necessary)

If error codes indicate a problem with the transmission control module (TCM), locate the module, usually found near the transmission or under the dashboard.
Disconnect the battery and the electrical connectors from the TCM.
Inspect for damage; if necessary, replace with a new module and reprogram it according to the manufacturer’s instructions.
