Got a. 2001 Nissan Pathfinder the obd isn't lighting up my reader which fuse would it be
The OBD (On-Board Diagnostics) system in a 2001 Nissan Pathfinder is powered by the vehicle's battery and is controlled by the Engine Control Module (ECM). If the OBD port isn't lighting up your reader, it could be due to a blown fuse.
In your Pathfinder, the OBD fuse is located in the fuse box under the dashboard on the driver's side of the vehicle. The fuse you need to check is the 10A fuse labeled "ECM" or "ECU". You can consult your vehicle owner's manual or the fuse box cover for the exact location of the ECM fuse.
If the ECM fuse is intact, there may be a problem with the OBD system itself or the wiring connecting it to the ECM. In that case, it's best to have a qualified mechanic or technician diagnose the issue to prevent further damage to your vehicle.
