DTC U0415:68 [VEHICLE CONTROL MODULE (US)] DETECTION CONDITION AND POSSIBLE CAUSE
| System malfunction location |
Error signal received from DSC HU/CM |
| Detection condition |
- When any of the following conditions is met.
- The vehicle control module (VCM) receives the following error signals from the DSC HU/CM for 10 s.
- Vehicle longitudinal acceleration
- Brake fluid pressure from master cylinder
- Yaw rate (vehicle turning angle speed)
- Rotation speed of each wheel
- The vehicle control module (VCM) detects that the brake signals between DSC HU/CM and the following modules did not match for 10 s during brake pedal operation while the vehicle is being driven.
- PCM
- Front radar sensor
- body control module (BCM)
- The vehicle control module (VCM) detects that a fail-safe is operated based on a deceleration request for 30 min while the vehicle is being driven.
