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.
Body Control Module (BCM)
| Refer to COMPONENT INDEX . |
The BCM receives input from the TTPM module during tire programming. When the TTPM receives a tire pressure from a sensor during a manual tire ID learn process, the TTPM requests the BCM to sound the horn briefly to indicate to the vehicle owner the tire pressure was received for that selected tire. The system will then advance to the next tire for programming. More information for tire programming can be found in the UConnect™ Radio Display service information.
