The body control module (BCM) receives a radio frequency (RF) transmission from each tire pressure sensor. Each sensors RF transmission contains its own unique identification (ID) code that must be learned into the BCM memory. Once all 4 IDs have been learned and vehicle speed is 25 mph, or greater, the BCM continuously compares IDs in received transmission to its learned IDs to determine if all 4 sensors are present.
The ignition is ON.
The BCM has not undergone the tire pressure sensor learn procedure.
The driver information center (DIC) displays the SERVICE TIRE MONITOR warning message.
• | A current DTC will clear when the BCM has undergone the sensor learn procedure. |
• | The electronic brake control module (EBCM) automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles. |
A newly replaced BCM will set DTC C0775 on its initial ignition ON cycle.
