DESCRIPTION

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

DTC No.	Detection Item	DTC Detection Condition	Trouble Area
U010087	Lost Communication with ECM/PCM "A" Missing Message	After 3 seconds or more have elapsed since turning the lane tracing assist system on and the ignition switch to ON, while the vehicle speed is 5 km/h (3 mph) or more, a communication malfunction between the forward recognition camera and the ECM is continuously detected for 5 seconds or more	CAN communication system
U012587	Lost Communication with Multi-axis Acceleration Sensor Module Missing Message	After 3 seconds or more have elapsed since turning the lane tracing assist system on and the ignition switch to ON, while the vehicle speed is 5 km/h (3 mph) or more, a communication malfunction between the forward recognition camera and the G sensor (airbag sensor assembly) is continuously detected for 5 seconds or more	CAN communication system
U012687	Lost Communication with Steering Angle Sensor Module Missing Message	After 3 seconds or more have elapsed since turning the lane tracing assist system on and the ignition switch to ON, a communication malfunction between the forward recognition camera and the steering sensor is continuously detected for 5 seconds or more	CAN communication system
U012987	Lost Communication with Brake System Control Module Missing Message	After 3 seconds or more have elapsed since turning the lane tracing assist system on and the ignition switch to ON, a communication malfunction between the forward recognition camera and the skid control ECU (brake actuator assembly) is continuously detected for 5 seconds or more	CAN communication system
U013187	Lost Communication with Power Steering Control Module Missing Message	After 3 seconds or more have elapsed since turning the lane tracing assist system on and the ignition switch to ON, a communication malfunction between the forward recognition camera and the power steering ECU (rack and pinion power steering gear assembly) is continuously detected for 5 seconds or more	CAN communication system
U015587	Lost Communication with Instrument Panel Cluster (IPC) Control Module Missing Message	After 3 seconds or more have elapsed since turning the lane tracing assist system on and the ignition switch to ON, a communication malfunction between the forward recognition camera and the combination meter assembly is continuously detected for 50 seconds or more	CAN communication system

PROCEDURE

1.	CHECK FOR DTCs

(a) Clear the DTCs.

Chassis > Lane Control > Clear DTCs

(b) Reproduce the vehicle conditions that were present when the DTCs that were noted were stored.

HINT:

If the detection conditions are not met, the system cannot detect malfunctions.

Chassis > Lane Control > Trouble Codes

Result	Proceed to
CAN communication system DTC is not output	A
CAN communication system DTC is output	B

USE SIMULATION METHOD TO CHECK
