TPMS Warning Indicator

The IPC receives TPMS data from the BCM. The BCM receives the tire pressure status message from the TPM module. If the BCM determines the tire pressure has exceeded the low tire pressure limits, a tire pressure status message is sent to the IPC to illuminate the TPMS warning indicator. If a TPMS fault condition exists, the BCM sends the tire pressure status message to the IPC. The IPC flashes the TPMS warning indicator for 75 seconds, then illuminates the indicator continuously.

When the TPMS is in tire train mode, the BCM sends a message to the IPC to flash the TPMS warning indicator.
