ECM/Mem-Cal - 1986-91 Models With Mem-Cal: Repair

To repair this condition use the following procedure. This procedure supersedes any instructions regarding MEM-CAL installation dated prior to September, 1990.

1. Inspect the MEM-CAL to determine if a cork spacer is glued to the top side of the MEM-CAL assembly. If so, remove it prior to installation.
2. Align small notches with matching notches in the ECM MEM-CAL socket.
3. VERY GENTLY press down on the ends of the MEM-CAL until the locking levers are rotated toward the sides of the MEM-CAL.
   NOTE: To avoid ECM damage, do not press on the ends of the MEM-CAL unit until the levers snap into place. DO NOT  use any vertical force beyond the minimum required to engage the MEM-CAL into its socket.
4. While continuing light pressure on the ends of the MEM-CAL, use your index fingers to press the locking levers inward until they are snapped into place. Listen for click.
5. Install MEM-CAL cover and install ECM in vehicle.
