C0775 2018 GMC Sierra Code - Tire Pressure Monitoring System Sensors Malfunction
Quick Answer
If the Body Control Module (BCM) has been reprogrammed or replaced and the tire pressure sensor learn procedure has not been performed, the tire pressure monitor system indicator icon on the instrument cluster will flash for 1 min and then remain illuminated after the power switch is cycled ON and the instrument cluster bulb check is complete. Common causes include Relearn Low Tire Pressure System Sensors. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
