DTC C1A41: Brake Request Value Mismatch between ENG / EHV and Driving Support ECU [09/2014 - 10/2015]: Description

The skid control ECU assembly receives brake control request signals from the power management control ECU and driving support ECU.

When the request signals received from the power management control ECU and driving support ECU are not consistent, the skid control ECU assembly determines that a malfunction has occurred and sends a malfunction signal to the driving support ECU.

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