TPMS Warning Indicator
The IPC receives TPMS data from the BCM. If the BCM determines that 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 for 75 seconds, then illuminates the indicator continuously.
