dIsassemble ecu to clean contact poInts ’94-’97 vehIcles
In these steps you will disassemble the ECU and clean the contact points.
IMPORTANT: The steps on this page are for ’94-’97 model vehicles. If your vehicle is not a ’94-’97 skip the steps on this page.
1. With the ECU laid on a flat service, remove
six 5.5 mm bolts on the top half of the ECU.
2. Remove the top cover.
3. Gently remove the bottom cover as well.
4. Locate the contact point where the 6 Position chip will plug in.
5. Clean both the top and bottom of the con-
tact points. Ensure that the pins on the ECU
are showing copper.
NOTE: Most initial issues with the chip not working after being plugged in are caused because the contact
points were not clean enough. A solid connection between the 6 Position Chip and the contact points is
required in order for the chip to function correctly. The best way to clean the contact points is to scrape the
silicon with a sharp knife or razor blade. Then take a nylon pad such as a Scotch bright pad to remove the
remainder of the silicon so that the copper connections are exposed.
