    Q: How to replace the Engine Control Module (ECM) on Cadillac DTS?
    A:
    When replacing an Engine Control Module (ECM) one must first note the remaining values of engine oil life and automatic transaxle fluid because the default values at 100% will trigger an immediate oil change at 5000 km (3,000 mi) and automatic transaxle fluid change at 83000 km (50,000 mi) after the last maintenance. A scan tool will enable you to retrieve the percentages of engine oil life and transaxle fluid life so they can be documented. The engine should be off while you disconnect the negative terminal battery wire. Remove the engine harness electrical connector of the mass air flow/intake air temperature (MAF/IAT) sensor and detach the positive crankcase ventilation (PCV) fresh air tube quick connect fitting from the air duct as well as the secondary air injection (AIR) pump inlet tube quick connect fitting from the air cleaner upper housing. The first step involves breaking the air cleaner outlet duct connection with the Throttle Body followed by disengaging the lower housing clips then separating the air cleaner upper housing from its position. The technician should unlock the ecm electrical connector lever locks at the ecm while disconnecting the electrical connectors before removing the ecm from the air cleaner lower housing. The inspection of both the air filter assembly and maf/iat sensor inlet screen must occur prior to installing the new ecm. Additionally the housing and intake air duct must be checked for damage so necessary components can be replaced. The new ecm needs installation into the lower air cleaner housing after reattaching all engine harness electrical connectors and then completing the lever lock operation. Position the air cleaner upper housing correctly by letting its front tabs fit into the lower housing while tightening all lower housing clips. Attach the air cleaner outlet duct to the Throttle Body by tightening its clamp to 3 n.m (27 lb in) to prevent fault codes from appearing. The system needs the air pump inlet tube and pcv fresh air tube quick connect fittings to be connected after reconnecting the engine harness electrical connector to the maf/iat sensor. The last step involves connecting the negative Battery Cable followed by pcm programming.
