Eagle OBD1 Trouble Codes

Easy to follow step by step guide on how to gather and read obd1 trouble codes for eagle cars made between 1988 and 1996.

Difficulty Level - 2

Begin with the vehicle on level ground, in park with the emergency brake set.

Step 1 - Start by  locating the diagnostic connector under the glove box, the Eagle Summit connector will be in the fuse box.

Step 2 -  Ground a test light and insert the probe end into the number 1 terminal.

Step 3 -  Turn the ignition key to the "ON" position, observe the test light. Long blinks represent the "tenth" position of the code number while the short blinks represent the "ones" position of the code number. For example, the light blinks two long times, then blinks four short times the code number is twenty four. Turn the key "OFF", then "ON" again to restart the test.

Step 4 - Once the repairs have been made, disconnect the negative side of the battery for thirty seconds, then reconnect, (Note: The computer will need to cycle (usually within twenty five miles) before the check engine light is illuminated if a problem still exists).
