DESCRIPTION When a malfunction is detected between various ECUs and sensors, these DTCs are stored. |
DTC No. | Detection Item |
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 |
2
seconds after the power switch is turned on (IG), a communication error
between the skid control ECU (brake booster with master cylinder
assembly) and the forward recognition camera is detected for
approximately 5 seconds or more. | CAN communication system | |
U0131 | Lost Communication with Power Steering Control Module |
2
seconds after the power switch is turned on (IG), a communication error
between the power steering ECU (rack and pinion power steering gear
assembly) and the forward recognition camera is detected for
approximately 5 seconds or more. | CAN communication system | |
U0142 | Lost Communication with Body Control Module "B" |
2
seconds after the power switch is turned on (IG), a communication error
between the main body ECU (multiplex network body ECU) and the forward
recognition camera is detected for approximately 5 seconds or more. |
CAN communication system | |
U0155 | Lost Communication with Combination Meter |
2
seconds after the power switch is turned on (IG), a communication error
between the combination meter assembly and the forward recognition
camera is detected for approximately 50 seconds or more. |
CAN communication system | |
U0293 | Lost Communication with HV ECU |
2
seconds after the power switch is turned on (IG), a communication error
between the hybrid vehicle control ECU and the forward recognition
camera is detected for approximately 5 seconds. |
CAN communication system | PROCEDURE
(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
