How to program the Engine Control Module on Buick Century?

Secondly you need to acquire the Vehicle Identification Number for programing the Engine Control Module. The Techline terminal allows you to choose Service Programming then Tech 2, Reprogram ECU, Off-Board Programming Adapter as ECU location. Follow the correct Off-Board Programming Adapter harness connector to link the control module along with the Off-Board Programming Adapter and Tech 2. The Service Programming Request Information function on the Tech 2 allows you to receive the access code from the control module before exiting this function Connect the Tech 2 to the Techline terminal after detaching it from the Off-Board Programming Adapter then turn it ON. The procedure requires users to enter vehicle VIN numbers into the Techline terminal until a database connection message appears. Chose the programming type and select its corresponding calibration file after verifying safe connections are established. The Techline terminal generates a summary screen of your selected information which you can confirm until it automatically sends the calibration files to the Tech 2. After completing the download process turn OFF the Tech 2 then disconnect it from Techline and relink it to the Off-Board Programming Adapter. Select Service Programming on the Tech 2. The programming procedure must be done after securing all connections and updating the Techline operating software because turning OFF the Off-Board Programming Adapter during interruptions may cause programming failure. The control module must be replaced when reprogramming fails. Last step includes choosing Program from the Tech 2 and closing Service Programming after downloading finishes while powering off the Off-Board Programming Adapter.

What does the service of the engine control module (ECM) typically involve on Buick Century?

Service operations for the powertrain control module (PCM) focus on the replacement of the unit or programming electrically erasable programmable read-only memory (EEPROM). A pcm inspection must take place to determine correct component functionality before installation. Install a new service pcm immediately after pcm removal but programming is necessary because the new unit lacks pre-programmed data. Dtc p0602 signals an eeprom failure because the memory either never received programming or is not functioning correctly. Preventing electrostatic discharge damage requires you to stay away from both connector pins and circuit board soldered components. It is essential to kill the ignition power during any connector work on pcm units or power disconnects of battery leads along with pcm pigtails/pcm fuses/jumper cables. Before starting removal processes a technician must retrieve engine oil life percentage data through the scan tool because failure to program new module data will trigger a default engine oil life of 100% that requires an oil change after 5000 km (3,000 MI). The next step requires users to disconnect the negative Battery Cable followed by separating the air cleaner housing cover assembly from the vehicle. The installation process begins by setting aside the pcm assembly and connector harness from the air cleaner housing space. Following the pcm disconnect of its connectors you should remove the pcm. Connect the pcm to connectors before tightening them to 8 n.m (71 lb in) and install it together with the harness into the air cleaner housing before placing on the cover assembly and reattaching the negative Battery Cable. Programming of the new pcm needs to be done according to requirement.
