System Tests: Notes

WARNING: This page is about a different car, the 2000 Ford Windstar and 1999 Ford Windstar. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Always check module power and ground circuits prior to replacing a control module. See appropriate wiring diagram in GROUND DISTRIBUTION and/or POWER DISTRIBUTION articles in WIRING DIAGRAMS.

NOTE: Many steps in the following tests refer to various connectors. These connector and terminal identifications are in illustrations. See Figure -Figure under CONNECTOR IDENTIFICATION.

NOTE: The following procedures were written specifically for use with New Generation Star (NGS) tester. Other generic scan tools can be used, but may have limited functions.

NOTE: After repairs are complete, perform data link diagnostic test. See DATA LINK DIAGNOSTIC TEST under SELF-DIAGNOSTIC SYSTEM.

CAUTION: Be careful when probing fuse junction box, power distribution box or any connectors. Damage will result to connector receptacle if probe or terminal being used is too large. Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage may result.
