System Tests: Notes

WARNING: Disable air bag system before working around steering column or removing any air bag system component. See AIR BAG RESTRAINT SYSTEMS article in RESTRAINTS.

CAUTION: Careful when probing the fuse junction panel, power distribution box or any connectors. Damage will result to connector receptacle if probe or terminal used is too large.
CAUTION: Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage may result.
NOTE: Before beginning SYSTEM TESTS, perform PRELIMINARY INSPECTION  under TROUBLE SHOOTING.
