Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Replace and Program ECU or Reprogram ECU
To program a replacement or an existing ECU, perform the following procedure:
- Access the Service Programming System (SPS) and follow the on-screen instructions.
- On the SPS Supported Controllers screen, select P16 Instrument Cluster - Programming and follow the on-screen instructions.
- At the end of programming, choose the "Clear All DTCs" function on the SPS screen.
Programming this ECU using SPS does not program the odometer value. The odometer information will be pre-programmed to the replacement instrument cluster.
