Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery's negative terminal to ensure safety.

2. Check Transmission Fluid

Remove the transmission dipstick (if equipped) and wipe it clean.
Reinsert the dipstick fully, then remove it again to check the fluid level.
If low, add the manufacturer-recommended transmission fluid (Toyota Type T-IV or equivalent).
If dirty, consider a fluid change.

3. Inspect Gear Selector Linkage

Locate the gear selector assembly.
Inspect the linkage for any signs of wear or disconnection.
Tighten any loose connections and realign as necessary.
Lubricate moving parts to ensure smooth operation.

4. Test Brake Pedal Switch

Locate the brake pedal switch under the dashboard.
Use a multimeter to check the continuity of the switch when the pedal is pressed.
Replace the switch if it is faulty.

5. Inspect Clutch or Fluid Pump (if necessary)

For manual transmissions, check the clutch fluid reservoir for proper fluid level; refill as needed.
If the clutch is not engaging, inspect the clutch master and slave cylinders for leaks.
For automatic transmissions, inspect the pump operation by checking for signs of wear or malfunction.
