Section 15 (Wireless Control Module (WCM) - Lancer Evolution): Diagnosis: Warnings/Alarms
WARNING: This page is about a different car, the 2008 Mitsubishi Lancer. However, it is still accessible from the selected car via links, so may be relevant.
If the TPMS fails or the tire pressure is low, the WCM warns the driver of that state by the TPMS warning light and the multi information display in the combination meter.
