How to replace the Engine Control Module (ECM) on Cadillac CTS?

Before replacing the Engine Control Module (ECM) verify that the ignition is off to protect the machine components. Disconnection of the engine control module ground wire from the ECM starts by removing its screw that secures the wire to the module. Touching the connector pins should be avoided to stop electrostatic discharge damage from occurring. You must open the release levers before you disconnect the ECM connectors from the Engine Control Module. Start your replacement of the ECM by removing the nuts attached to the ECM bracket and then pulling out the ECM from its position. Position the ECM to the ECM bracket with the ignition off before securing it with nuts that need to be tightened to 8 N.m (71 lb in). Check how the harness connectors match with ECM connectors before guiding all parts into place with the release lever securely locked. Replace the screw which secures the ECM ground wire to the ECM then tighten this screw to 4.5 N.m (40 lb in). Use the Service Programming System to program the ECM. After programming the new GM SPO Replacement Part to replace an ECM it immediately acquires the fuel continue password. The 10-minute or 30-minute relearn process needs to be executed for learning the current vehicle's theft deterrent control module password whenever an ECM transfers to a different vehicle. Programming of the theft deterrent system components becomes necessary after installing an ECM which originated from another vehicle. Also run the idle learn procedure.
