What precautions should be taken before programming an Engine Control Module on Cadillac Eldorado?

Check for charging system concerns before programming a control module because you need to fix all such problems before beginning. The battery requires sufficient voltage between 12 and 16 volts to begin programming therefore battery charging is essential. A battery charger must remain disconnected because improper voltage or instability may cause a programming failure or destructive damage to the control module. All battery-consuming systems need to be disabled during programming including twilight sentinel and interior lights and daytime running lights (DRL), hvac systems and engine cooling fans. Programming must occur while the Ignition Switch remains in position with engine off yet the operator should not alter its setting unless the tool specifies to do so. The procedure requires users to verify proper connection security for all tools beginning with rs-232 along with the data link connector (DLC) and to abstain from manipulating the tool harnesses to stop interruptions that might lead to programming failure or control module damage.
