TPMS Control Unit Inputs and Outputs for 20P Connector: Indicators
All indicators are in the gauge control module: The low tire pressure indicator (LED indicator), the four tire indicators (on the multi-information display) to show which tire is affected, and the TPMS indicator (on the multi-information display) that comes on only if there's a problem with the system. The message indicator (LED indicator) comes on when there is one or more indicators on in the multi-information display. When two or more tire pressures are low, the low tire pressure indicator comes on about 5 seconds before the appropriate tire indicator. Once low pressure is detected, the system scans all four tire pressure sensors to ensure that it turns on the correct tire indicator.
