DTC Detection Condition |
Trouble Area |
|---|---|---|---|
|
U0101 |
Lost Communication with TCM |
2 seconds after the power switch is turned on (IG), while the vehicle is being driven at 1 km/h or 1 mph or more, a communication error between the TCM (hybrid vehicle control ECU) and the forward recognition camera is detected for approximately 5 seconds or more. |
CAN communication system |
|
U0123 |
Lost Communication with Yaw Rate Sensor Module |
2 seconds after the power switch is turned on (IG), while the vehicle is being driven at 1 km/h or 1 mph or more, a communication error between the yaw rate sensor (airbag ECU assembly) and the forward recognition camera is detected for approximately 5 seconds or more. |
CAN communication system |
|
U0126 |
Lost Communication with Steering Angle Sensor Module |
2 seconds after the power switch is turned on (IG), a communication error between the steering sensor and the forward recognition camera is detected for approximately 5 seconds or more. |
CAN communication system |
|
U0129 |
Lost Communication with Brake System Control Module |

PROCEDURE
|
1. |
CHECK FOR DTCs |
(a) Clear the DTCs.
Chassis > LKA/LDA > Clear DTCs
(b) Make sure that the DTC detection conditions are met.
HINT:
If the detection conditions are not met, the system cannot detect the malfunction.
(c) Check for DTCs.
Chassis > LKA/LDA > Trouble Codes
