Code C1245 Cadillac Description
The C1245 diagnostic trouble code (DTC) for Cadillac vehicles indicates a problem with the tire pressure monitoring system (TPMS), specifically detecting high or low tire pressure. This code is triggered when the TPMS sensor detects that one or more tires have pressure outside of the acceptable range set by the manufacturer. Proper tire pressure is essential for safe driving, fuel efficiency, and overall vehicle performance. Incorrect tire pressure can lead to uneven tire wear, reduced traction, decreased fuel efficiency, and potential tire blowouts.
