CAUTION!
The following steps should only be carried out while working at an anti-static workstation (Illustration 1) and wearing a grounding wrist strap.
1.
Position the ECM on the anti-static work mat so that when facing the multiplugs, the red multi-plug is at the upper right and the black multi-plug to
the lower left.
2.
Note the position of the top cover with its mounting tab to the ECM housing. Mark both the cover and the casing using a felt tip marker to assist
reassembly. Remove the four tamper resistant retaining screws of the top cover (the cover adjacent to the red multi-plug) using a Torx 20
Anti-Tamper screw bit.
3.
Obtain a wooden block approximately 6 x 6 x 1 inches. Remove the seven retaining screws of the printed circuit board (Illustration 2). Lift the
printed circuit board and support it on the wooden block so that no strain is applied to the ribbon connectors. Allow a clearance space so that no
damage can occur from contact with the mounting brackets.
4.
Remove the appropriate PROM covers by lightly gripping the PROM cover with a pair of pliers and using a side to side rocking action.
