Where to hook code reader 2002 envoy
Your OBD II code reader won't work on that vehicle.
The 2009 Nissan Murano has the most common hook-end wiper arms. See sources and related links below for installation videos. Also, purchase the replacement blades first and there will be additional instructions/illustrations on the replacement packages. Locate and press the tab or button where the wiper blade is inserted into the hook of the wiper arm and pull wiper blade out of hook. You may have to rotate and flex the blade to make enough clearance for the hook to pass through.
There should be a plug adapter spot right under the steering wheel and dash assembly, should just plug right in... i have a 96 and i work at O'Reillys auto parts, we have a code reader that reads all nissans from 88 to current....so if is the right code reader it should just install as i said above hope that helps a little
To hook up a code reader to a 2000 Volvo, locate the OBD-II diagnostic port, which is typically found under the dashboard near the driver's side, just above the brake pedal. Plug the code reader's connector into this port. Once connected, turn on the vehicle's ignition (without starting the engine) to power the code reader, allowing it to communicate with the car's onboard computer. Follow the reader's instructions to retrieve any diagnostic trouble codes.
If you are sitting in the steering wheel the hook up will be located by your right knee under the dash.
passenger side panel, above left knee
you have to hook up a special reader to your computer to find out the code.
