Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, screwdrivers, transmission fluid, funnel, and rags.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check Transmission Fluid

Locate the transmission dipstick.
Remove the dipstick and wipe it clean with a rag.
Reinsert the dipstick fully and remove it again to check the fluid level.
If low, add the appropriate type of transmission fluid as specified in the owner's manual.
If the fluid is dark or has a burnt smell, a fluid change may be necessary.

3. Inspect Transmission Linkage

Open the hood and locate the transmission linkage.
Visually inspect for any loose or damaged components.
Use a socket set to tighten any loose bolts or replace damaged parts as necessary.

4. Test Brake Light Switch

Locate the brake light switch, typically mounted near the brake pedal.
Disconnect the electrical connector and use a multimeter to test for continuity.
Replace the brake light switch if it is faulty.

5. Clear Error Codes

Reconnect the OBD-II scanner to the vehicle's diagnostic port.
Follow the scanner's instructions to clear any stored error codes.
Test if the vehicle can now shift into reverse.
