Component Tests: Notes

CAUTION: When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery.

CAUTION: Static electricity can destroy integrated circuits in instrument cluster and VSS calibrator. Before servicing these components, ground yourself and work area to discharge static electricity.

NOTE: If all components in cluster are inoperative, check instrument cluster power and ground circuits. If power and ground circuits are okay, replace instrument cluster.
