Solution

1. Preparation

Gather tools and parts required for the diagnosis and repair.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Check Transmission Fluid

Locate the transmission dipstick, remove it, and wipe it clean.
Insert the dipstick back and remove it again to check the fluid level. The fluid should be within the marked range.
If the fluid is low, add the recommended transmission fluid type (usually Toyota ATF WS) until it reaches the proper level.

3. Inspect and Replace Brake Switch

Locate the brake switch, usually found above the brake pedal.
Disconnect the wiring harness and remove the switch using a socket set.
Test the switch with a multimeter to ensure it activates when the pedal is pressed; replace if faulty.
Reinstall the new brake switch and reconnect the wiring harness.

4. Check Shift Cable/Linkage

Inspect the shift cable for any visible damage or disconnections at both the transmission and the shifter.
If damaged, remove the cable by detaching the connectors using pliers, and install a new shift cable by reversing the removal process.
Ensure the cable is properly adjusted and secured.

5. Electrical System Check

Use a multimeter to check the battery voltage; it should be around 12.6 volts with the engine off.
Inspect all electrical connections to the transmission control module, ensuring they are clean and secure. Repair or replace any corroded connectors.

6. Test Drive

Reconnect the negative battery terminal and start the engine.
Test the vehicle by attempting to shift into gear and observe if the issue persists.
