DTC C1A41: Brake Request Value Mismatch between ENG / EHV and Driving Support ECU [11/2017 - 03/2019]: Description

The brake actuator assembly (skid control ECU) receives brake control request signals from the ECM and driving support ECU assembly.

When the request signals received from the ECM and driving support ECU assembly are not consistent, the brake actuator assembly (skid control ECU) determines that a malfunction has occurred and sends a malfunction signal to the driving support ECU assembly.

If the driving support ECU assembly receives the malfunction signal, DTC C1A41 is stored.
