Ask our experts now! 1988 Buick LeSabre, Park Ave Engine Troubleshooting Print this article All 1988 Buicks, including the LeSabre and Park Avenue, have an on-board diagnostic system that can assist in troubleshooting many engine problems. The system predates current OBD-II standardization, however, so current code scanners will not work with the system. However, all GM vehicles built before 1996 can be placed into a self-testing mode. While accessing a vehicle's fault codes are never the absolute answer to engine troubleshooting, the system can tell you where recent malfunctions have occurred.

Locate the Buick's Assembly Line Data link. In both the LeSabre and the Park Avenue, the ALDL can be found directly beneath the steering wheel
2 Connect the "A" and "B" ports on the ALDL with jumper wire. The two ports are on the top row of slots, and to the far right. Insert one end of the jumper wire into the "A" port at the end of the row, and insert the other end into the "B" port, which will be to the immediate left.
3 Start the vehicle's electrical system with the ignition key. Leave the engine off.
4 Write down how many times the check engine light flashes. General Motors fault codes are two numbers. A fault code's first number will flash, and that will be followed by a brief pause. The second number will be represented by short flashes. For example, fault code 31 will be conveyed by three flashes, a short pause, and 1 short flash.
5 Look up the fault codes online. The fault codes for both the LeSabre and the Park Avenue will not be in their respective owner's manuals. Once you have found the fault code definitions, copy them out next to the code numbers you jotted down.
6 Open the engine compartments on either the LeSabre or the Park Avenue. Start at the top of your malfunction list and work down. Cross out codes once you know they are not causing the problems the vehicle is currently experiencing.
