DTC C019604 indicates: integrated inertial sensor fault (hardware, temperature, range, internal fault) (ESP only).
What It Means
DTC C019604 indicates: integrated inertial sensor fault (hardware, temperature, range, internal fault) (ESP only). This code is set by the Brake System control module when it detects the condition above. It typically points to an electrical, wiring, or component-level fault rather than a software-only glitch. Technicians should read the freeze-frame data and check the related circuits, connectors, and module supply before replacing parts.
What To Do
Stop the vehicle as soon as it is safe to do so and contact an authorized service center immediately. Do not continue driving — this fault may affect safety-critical functions such as braking, restraint, or high-voltage isolation.
