C1421 is a chassis diagnostic trouble code. It identifies a fault related to Damper Lf Circuit Short To Battery Ford Jaguar Open Or Short In Master Cylinder Pressure Sensor Toyota Rear Differential Clutch Performance Jeep Chrysler. The chassis control module monitors this circuit or component continuously and sets C1421 when the signal or value is outside the expected range, implausible or missing. This can reduce braking, stability or steering assistance and usually lights the ABS or a related warning lamp. The base function may still work, but performance can be affected, so the fault should be diagnosed. Diagnosis generally means inspecting the related wiring, connectors and power/ground references, then verifying the component against specification with a scan tool.
