Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, transmission fluid dipstick, funnel.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shock.

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 recommended transmission fluid (Toyota ATF WS).
Inspect the fluid for color (should be red) and smell (should not smell burnt). If the fluid is dark or burnt, a fluid change may be necessary.

3. Inspect Linkage and Cables

Locate the transmission linkage under the vehicle.
Visually inspect for any signs of wear, rust, or disconnection.
If damaged, replace the linkage or cable as needed.

4. Test Brake Switch

Locate the brake switch, usually near the brake pedal.
Use a multimeter to check for continuity when the brake pedal is pressed.
If the brake switch is faulty, replace it.

5. Check Battery and Alternator

Use a multimeter to check the battery voltage; it should read around 12.6 volts when fully charged.
Start the vehicle and check the voltage again; it should be between 13.7 to 14.7 volts.
If readings are outside these ranges, the battery or alternator may need replacement.

6. Replace Fuses (if necessary)

Locate the fuse box and check the fuses related to the transmission control module.
Replace any blown fuses with the same amperage rating.
