Tire pressure monitoring feedback and auxiliary inflation signaling on the 2023 Chevrolet Blazer are regulated by tire pressure monitoring sensors, body control modules, and the horn and turn signal circuits.
How to Fix It:
-
Park Safely and Engage Parking Brake: Pull over to a safe location, keep the vehicle running in Park (P), and ensure the parking brake is set.
-
Add Air to Target PSI: Begin filling the under-inflated tire with compressed air while watching the turn signal lights for status cues.
-
Listen for the Horn Chirp: Stop inflating immediately when the vehicle horn sounds once, signaling that you have reached the exact target pressure specified on the door placard.
