TPMS Warning Indicator

The IPC  receives the tire pressure warning indicator request from the GWM  over the High Speed Controller Area Network 3 (HS3-CAN). The GWM  receives the tire pressure warning indicator request from the BCM over the High Speed Controller Area Network 1 (HS1-CAN).

If the BCM  determines the tire pressure has exceeded the low tire pressure limits, the tire pressure warning indicator request message is sent to the IPC  to illuminate the TPMS  warning indicator.

If a TPMS  monitor or sensor fault condition exists, the BCM  sends the tire pressure warning indicator request message to the IPC  to flash the TPMS  warning indicator. The IPC  flashes the TPMS  warning indicator for 75 seconds then turns the indicator on solid.
