Diagnostic 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.

NOTE: When using diagnostic tests, DO NOT skip any test steps unless instructed to do so, or incorrect diagnosis may result.

NOTE: Diagnostic tests are written specifically for Diagnostic Readout Box (DRB-III). A generic scan tool may not be capable of performing all necessary test functions.
