Vehicle Damage Warnings
WARNING: This page is about a different car, the 2001 Dodge Viper and 2000 Dodge Viper. However, it is still accessible from the selected car via links, so may be relevant.
Before disconnecting any control module, make sure the ignition is off. 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 so as 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.
