Vehicle Damage Warnings

CAUTIONS:
^ Make sure the ignition is OFF before disconnecting any control module. Failure to do so could damage the module.

^ When testing voltage or continuity at any control module, use the terminal side (not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion.

^ Be careful when performing electrical tests to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult.
