How to Troubleshoot the Check Engine Light on a 1996 Acura TL

The 1996 Acura TL uses various sensors, solenoids and valves to ensure that the car runs normally. When one of these components fails, you need to use a diagnostic scan tool to diagnose the problem and retrieve the error code from the Acura's electronic control unit. Once you have the error code, you can fix the problem. These diagnostic machines are available from some auto parts stores.

Things You'll Need

• OBD II scan tool

Instructions

1. Locate the onboard diagnostics (OBD) access port to the left of the fuse panel. The access port will be an essentially rectangular plug that accepts the OBD scan tool's plug. Honda, which owns Acura, uses the OBD II system on the 1996 Acura TL. Your diagnostic tool needs to be able to communicate with an OBD II diagnostic computer.

2. Plug the OBD tool into the access port.

3. Turn on the OBD scan tool and turn the ignition to the "On" position.

4. Wait for the OBD tool to power up and for the display to read "OK." When this happens, the tool has finished scanning the computer and retrieved the codes. You can unplug the tool now and shut off the ignition.

5. Access the menu option on your scan tool and scroll to the section that stores codes on the device. This will normally be under a heading like "Stored Codes" on most OBD tools. Reference your TL's service manual to translate the engine codes.
