Troubleshooting a Dead Toyota OBD2 Port

Check the Fuse: Locate your car’s fuse box (usually under the steering wheel or in the engine compartment) and consult your owner’s manual to identify the OBD2 port fuse. Inspect the fuse visually and replace it if necessary.
Inspect the Wiring: Visually examine the wiring leading to the OBD2 port for any signs of damage, corrosion, or loose connections. If you find any issues, repair or replace the affected wiring.
