The center of the electronic engine control (EEC) system is a microprocessor called the PCM. The PCM receives input from sensors and other electronic components (switches, relays). Based on the information received and programmed into its memory, the PCM generates output signals to control various relays, solenoids and actuators. There are several different types of PCMs in use for this model year. Refer to the Vehicle PCM Application Table below for PCM types and their applications.
Removal & Installation
- Powertrain control module electrical connectors
- PCM retaining bolt
NOTEAny powertrain control module (PCM) replacement will require that ALL customer keys are available to be programmed at the time of installation. PCM replacement DOES NOT require new keys. Retrieve the module configuration. Carry out the module configuration retrieval steps of the Programmable Module Installation procedure.
Release the clips and disconnect the 3 PCM electrical connectors.
- Install the PCM and the bolts.
- Tighten to 89 ft. lbs. (10 Nm).
- Connect the 3 PCM electrical connectors and install the clips.
- Restore the module configuration. Carry out the module configuration restore steps of the Programmable Module Installation procedure.
- Reprogram the Passive Anti-Theft System (PATS). Carry out the Key Programming Using Two Programmed Keys procedure.
Using a high-impedance digital multi-meter, test the PCM for correct power and ground inputs and outputs, according to the pin location chart.
