Does not come on |
U0125 |
Lost Communication with Yaw Rate Sensor Module |
While the vehicle speed is 36 km/h (22 mph) or more and the dynamic radar cruise control system is operating, a communication error between the yaw rate sensor and the millimeter wave radar sensor assembly is detected for approximately 1 second or more. |
|
Does not come on |
U0126 |
Lost Communication with Steering Angle Sensor Module |
While the vehicle speed is 36 km/h (22 mph) or more and the dynamic radar cruise control system is operating, a communication error between the steering angle sensor and the millimeter wave radar sensor assembly is detected for approximately 1 second or more. |
|
Does not come on |
U0129 |
Lost Communication with Brake System Control Module |
While the vehicle speed is 36 km/h (22 mph) or more and the dynamic radar cruise control system is operating, a communication error between the skid control ECU (master cylinder solenoid)*1 or skid control ECU (brake actuator assembly)*2 and the millimeter wave radar sensor assembly is detected for approximately 2.5 seconds or more. |

High Power Supply Voltage Malfunction (C1417)
DESCRIPTION
If a malfunction is detected in the power supply circuit, the skid control ECU
(brake actuator assembly) stores this DTC and the fail-safe function prohibits ABS
operation.
This DTC is stored when the +BS terminal voltage deviates from the DTC detection
condition due to a malfunc ...
