C1A41 - Pre-Collision System
DTC C1A41 Brake Request Value Mismatch between ENG / EHV and Driving Support ECUDESCRIPTION
DTC Detection Condition:
The skid control ECU receives brake control request signals from the ECM and driving support ECU. When the request signals received from the ECM and driving support ECU are not consistent, the skid control ECU 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 C1A41/52 is output. Although the skid control ECU sends a malfunction signal to the driving support ECU, the ABS does not output a relevant malfunction detection DTC.
