Ford Full-Size Vans 1989-1996 Repair Guide



See Figure 1

Electronic modules, such as instrument clusters, powertrain controls and sound systems are sensitive to static electricity and can be damaged by Electro Static Discharge (ESD) which are below the levels that you can hear "snap" or detect on your skin. A detectable snap or shock of static electricity is in the 3,000 volt range. Some of these modules can be damaged by a charge of as little as 100 volts.

The following are some basic safeguards to avoid static electrical damage:

Leave the replacement module in its original packing until you are ready to install it.
Avoid touching the module connector pins
Avoid placing the module on a non-conductive surface
Use a commercially available static protection kit. These kits contain such things as grounding cords and conductive mats.
