2000 Chevrolet Monte Carlo Parts Questions & Experts Answers

• Q: How to service the Engine Control Module, and what steps are involved in replacing or programming the EEPROM on 2000 Chevrolet Monte Carlo?

  A: To maintain the pcm one can use either new units or restore the eeprom content when necessary. Begin by confirming that the installed pcm component is the correct one before proceeding with the service pcm installation which demands programming procedures. The unprogrammed status or eeprom failure indicates that dtc p0602 is present. The safety of components on the circuit board requires you to keep your hands off both connector pins and soldered elements and to switch off the ignition before handling pcm connectors or disconnection of power sources. Start by taking off the negative Battery Cable followed by removing the electrical connector of the iat sensor. First disconnect the clamp holding the air intake duct to the air cleaner housing then the Throttle Body before removing the duct carefully. You will need to remove two screws on the air cleaner housing parts before you remove the air cleaner housing cover assembly. Perform the pcm removal task after removing the pcm together with its harness from the housing through disconnecting all original connectors. Reinstallation requires procuring the pcm connectors after which the pcm unit with harness needs to be carefully inserted into the pcm housing followed by attaching the air cleaner housing cover assembly using its two screws. Next install the air intake duct while securing the clamp with force. Finish the procedure by reattaching the negative Battery Cable yet terminal programming of the eeprom requires a new pcm installation. Note that the replacement pcm will only enable secondary air pump after accumulating a total of 10 miles.
