DESCRIPTION

When a malfunction is detected between various ECUs and sensors, these DTCs are stored.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area
U0100	Lost Communication with ECM / PCM "A"	While the vehicle is being driven at 1 km/h or 1 mph or more, a communication error between the ECM and the forward recognition camera is detected for approximately 5 seconds or more.	CAN communication system
U0101	Lost Communication with TCM	While the vehicle is being driven at 1 km/h or 1 mph or more, a communication error between the TCM (ECM) and the forward recognition camera is detected for approximately 5 seconds or more.	CAN communication system
U0123	Lost Communication with Yaw Rate Sensor Module	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
U0129	Lost Communication with Brake System Control Module	2 seconds after the engine switch is turned on (IG), a communication error between the skid control ECU (brake actuator 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 engine 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

1.	CHECK FOR DTCs

(a) Clear the 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.
