2006 Buick Rendezvous Parts Questions & Experts Answers

• Q: How to replace the Engine Control Module on 2006 Buick Rendezvous?

  A: A proper inspection of the pcm establishes its correctness before moving forward with replacement. The removal process begins by replacing the faulty pcm with a new service unit while properly providing broadcast code and production pcm number information to keep in service from start to end. A service programming procedure is necessary for the pcm so dtc p0602 will display when the eeprom becomes unprogrammed or malfunctions. Mark down the present engine oil lifetime via a scan tool before programming the replacement module because unprogrammed life data will result in 100 percent default and force an oil change within 5,000 km (3,000 mi) of the previous change. Start by disconnecting the negative Battery Cable and next remove the left diagonal brace and finally the air cleaner assembly cover to expose the pcm for raising out of the air cleaner assembly. The pcm requires removal after disconnecting the engine harness electrical connectors from it. Installing the new pcm requires users to connect engine harness electrical connectors to the pcm followed by placement of the pcm into the air cleaner assembly before reinstalling the air cleaner assembly cover by tightening screws to 4 n.m (35 lb in). After reattaching the left diagonal brace you should reconnect the negative Battery Cable. Installation of a fresh pcm requires proper programming before its use.
