DESCRIPTION
When a communication malfunction is detected between the forward recognition camera and an ECU or sensor, a DTC is stored.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
---|---|---|---|
U012587 | Lost Communication with Multi-axis Acceleration Sensor Module Missing Message | While the vehicle is being driven at 5 km/h (4 mph) or more and the lane control system is on, a communication error is detected between the yaw rate sensor (airbag ECU assembly) and forward recognition camera for approximately 5 seconds or more. | CAN communication system |
U012687 | Lost Communication with Steering Angle Sensor Module Missing Message | 2 seconds after the power switch is turned on (IG), while the lane control system is on, a communication error is detected between the steering sensor and forward recognition camera for approximately 5 seconds or more. | CAN communication system |
U012987 | Lost Communication with Brake System Control Module Missing Message | 2 seconds after the power switch is turned on (IG), while the lane control system is on, a communication error is detected between the skid control ECU (brake booster with master cylinder assembly) and forward recognition camera for approximately 5 seconds or more. | CAN communication system |
U013187 | Lost Communication with Power Steering Control Module Missing Message | 2 seconds after the power switch is turned on (IG), while the lane control system is on, a communication error is detected between the power steering ECU (rack and pinion power steering gear assembly) and forward recognition camera for approximately 5 seconds or more. | CAN communication system |
U015587 | Lost Communication with Instrument Panel Cluster (IPC) Control Module Missing Message | 2 seconds after the power switch is turned on (IG), while the lane control system is on, a communication error is detected between the combination meter assembly and forward recognition camera for approximately 50 seconds or more. | CAN communication system |
U029387 | Lost Communication with Hybrid Powertrain Control Module Missing Message | 2 seconds after the power switch is turned on (IG), while the vehicle is being driven at 5 km/h (4 mph) or more and the lane control system is on, a communication error is detected between the hybrid vehicle control ECU and forward recognition camera for approximately 5 seconds or more. | CAN communication system |
PROCEDURE
1. | CHECK FOR DTCs |
(a) Clear the DTCs.
Chassis > Lane Control > 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 > Lane Control > Trouble Codes Result | Proceed to |
