Step 1 - When a code is stored the "check engine" light will illuminate. Most of these trouble codes are made up of two digits and are accessible under the passenger seat.

Step 3 - Example, if the first blinking light flashes off and on twice, and the second blinking light flashes once the code number is 21.

Step 4 - To restart code gathering sequence shut the key off and then back on again.

Step 5 - To clear trouble codes after the repairs have been made turn the ignition key to the "on" position, disconnect the serial link mating plug, wait ten seconds and reconnect the plug. Switch the ignition switch to the "off" position for five seconds and turn the ignition key back on again.
