Removal & Installation: Notes

CAUTION: To prevent damage to ECM, ignition must be off before disconnecting or reconnecting any ECM power source (i.e.; battery, ECM connectors, ECM fuse, jumper cables, etc.). Replacement ECM's do not come with a "MEM-CAL" installed. Use "MEM-CAL" from original ECM.
CAUTION: When certain materials rub together, a transfer of electrons from one material to another may occur under special conditions. This results in an electrostatic charge (static electricity) being built up in one of the materials. When any conducting material comes in contact with the charged material, electrostatic discharge occurs, transferring electrons to the third material. Since electronic components used in control systems are designed to carry very low voltages, as little as a 30-volt charge created by static electricity can cause a total or degrading failure in ECM or other electronic components containing integrated circuits. Before servicing ECM, ground yourself and ground the work area to discharge stored electricity.
STATIC CHARGE (VOLTS)

Movement Causing Charge % Relative Humidity 10-20 % Relative Humidity 65-90
Handling Clear Plastic Bag 20,000 1200
Sliding Across Velour Seat 15,000 400
Walking Across Tile/Vinyl 12,000 50
Handling Vinyl Envelope 7000 600
CAUTION: DO NOT  remove part from packaging until ready to install. Ground any static proof package PRIOR to opening. DO NOT  touch electrical terminals of components unless properly grounded. DO NOT  lay electrical components on car seat, carpeting or dashboard. Use electrostatic protection mat and ground strap whenever possible. See Fig 1 .
