2010 Chevrolet Impala Parts Questions & Experts Answers

• Q: What does the service of the engine control module (ECM) typically involve on 2010 Chevrolet Impala?

  A: The service of the Engine Control Module (ECM) consists of either a new ecm installation or electrically erasable programmable read-only memory (EEPROM) programming. The inspection of the ecm needs to occur before replacement to verify its accuracy. Instal the new service ecm but programming becomes necessary since it arrives unprogrammed. The unprogrammed or malfunctioning state of eeprom generates the diagnostic trouble code p0602. Typical safety precautions for ecm connectors include not touching pins or soldered circuits of the circuit board and letting the ignition power off when maintaining ecm connectors as a safeguard against electrostatic discharges. Document the current engine oil limit before trying to program the replacement module because failing to do so will reset the oil life to 5,000 km (3,000 mi) from the previous maintenance date. The user needs a scan tool to acquire and save the number of percent of remaining engine oil. Cable the negative battery after you remove the left front inner fender brace as well as the air cleaner assembly from the vehicle. The ecm requires disconnection from its connectors that are attached to the air cleaner lower housing before extracting the ecm from its position. To install the ecm you should reposition it into the air cleaner lower housing before reconnecting electrical connectors and installing the air cleaner assembly and left front inner fender brace. Complete the installation by reconnecting the negative Battery Cable followed by ecm programming of the new system.
