DTC C1245 indicates a Low Tire Pressure Detected issue, while DTC U1300 signifies a Class 2 Data Link Communication Failure. These codes may point to problems with tire pressure monitoring or vehicle communication systems. Check the tire pressure sensor and ensure proper wiring or signal connection.

I have a 2006 Chevrolet Suburban 5.3L Vortec with a similar issue — a faulty HO2S Heater Control Circuit (Bank 2 Sensor 1). I'm trying to locate the fuse for this sensor, which is typically found in the engine compartment fuse box. A helpful video on sensor diagnostics was also very informative.
