You can reset the check engine light on your Saab using an OBD scan tool. OBD stands for On-Board Diagnostics. This is the computer that monitors all of the functions of your vehicle. Sensors are positioned throughout the vehicle that send trouble codes back to the computer if there is a malfunction in any of the systems. When you see the check engine light illuminate on your instrument panel, be sure to have the vehicle examined and repaired as soon as possible. After you have the repairs done, then you should reset the light in order to allow the computer to continue doing its job properly.

  1. 1

    Find the OBD port on the driver's side footwell just to the left of the main fuse panel and underneath the steering column. Check to make sure the port is the same size and same shape as the connector on the OBD scan tool. Then you will know that you have found the right port.

  2. 2

    Plug the scan tool into the port. Put the key into the ignition and turn it to the "on" position, but make sure the engine doesn't turn over. This will power on the OBD scan tool.

  3. 3

    Wait a minute for the OBD scan tool to read the codes, then press "OK" and "Clear" to clear the codes from the vehicle's computer. Turn the vehicle off and wait another minute.

  4. 4

    Turn on the engine and examine the instrument panel to make sure the check engine light has shut off. Turn the vehicle off and unplug the scan tool.

Tips and warnings

  • You can purchase an OBD scan tool from any auto parts retailer. If you don't wish to purchase one, most auto parts retailers will loan you their scan tool so you can read and erase the codes yourself.
