CAUTION: When certain materials rub together, a transfer of electrons from one material to another may occur under special conditions. This causes electrostatic charge (static electricity) build-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. Electronic components used in control systems are designed to carry very low voltages; a 30-volt charge created by static electricity can cause a total or degrading failure in PCM or other electronic components containing integrated circuits. Before servicing PCM, ground yourself, and ground the work area to discharge stored electricity.

STATIC CHARGE

Movement	Relative Humidity 10-20%	Relative Humidity 65-90%
Walking Across Carpet	35,000	1500
Handling Clear Plastic Bag	20,000	1200
Sliding Across Velour Seat	15,000	400
Walking Across Tile/Vinyl	12,000	50
Handling Vinyl Tote Bag	7000	600

CAUTION: DO NOT remove PCM from packaging until ready to install. Ground static-proof package BEFORE 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.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.

• You are missing required tools, torque specs, or safe lifting equipment.

• You are not confident in the next step or safety outcome.
