How to replace the Engine Control Module on Cadillac Seville?

Before replacing the powertrain control module (PCM) ensure the ignition system is turned off because it protects the module against damage occurring during power disconnection and connector handling. Start by jotting down current transaxle fluid and engine oil life indexes and proceed to disconnect the battery negative cable. Use a screwdriver to detach the intake air duct/resonator connection to the pcm housing and snap the Air Filter housing clamp locks on top of the air cleaner housing assembly to gain access to inspect the air cleaner cover and pcm. The technician should start by sliding the air cleaner element assembly to the fender to detach it from the air inlet assembly while also loosening the pcm connector bolts and disconnecting both pcm connectors before pcm removal. The off-board programming of the pcm should be finished prior to any installation process. Put the pcm in place along with its connectors then use a 71 lb in torque (8 N.m) value for the pcm connector screws. To install an air cleaner cover into the air inlet housing begin by attaching the assembly clamps before lining up the intake air duct/resonator assembly and using a screw to tighten the intake air duct clamp to 3 n.m (27 lb in). The last step requires the reconnection of the battery negative cable followed by any required pcm programming procedures.
