TPMS Warning Indicator
The IPC receives the TPMS data from the BCM over the MS-CAN. If the BCM determines the tire pressure has exceeded the low tire pressure limits, the tire pressure indication message is sent to the IPC to illuminate the TPMS warning indicator. If a TPMS fault condition exists, the BCM sends the tire pressure indication message to the IPC to flash the TPMS warning indicator.
