Hello!
Diagnostic trouble Code C0040 warns of a potential malfunction in one of the wheel speed sensors or the sensor's circuit. There are GVWs (gross vehicle weights) specific for each vehicle application, like 7200 lb., 7300 lb., 8,500 lb., and 8,600 lb. Click here to learn more about this code.
On the other hand, C0201 code means "Anti-Lock Brake System Enable Relay Contact Circuit." Simply put, your harness is open or shorted, and the relay circuit has poor electrical connections. Check for moisture, corrosion, and damaged/broken/bent/pushed out/corroded connector pins. Add dielectric gel to repel moisture and protect electrical components against corrosion. Too, you may also have to replace the ABS module, if needed.
