DESCRIPTION

The forward recognition camera communicates with each sensor and ECU via CAN communication.

If any malfunction is detected in a CAN communication circuit, one or more CAN communication system DTCs are stored.

DTC No. Detection Item DTC Detection Condition Trouble Area DTC Output from
U010087 Lost Communication With ECM/PCM "A" Missing Message When the dynamic radar cruise control system is operating, a communication malfunction between the ECM and forward recognition camera is detected for 5 seconds or more. CAN communication system Radar Cruise2
U012587 Lost Communication With Multi-axis Acceleration Sensor Module Missing Message When the vehicle speed is approximately 1 km/h (1 mph) or more, a communication error between the forward recognition camera and yaw rate sensor continues for 5 seconds or more. CAN communication system Radar Cruise2
U012687 Lost Communication with Steering Angle Sensor Module Missing Message When the engine switch on (IG) for 2 seconds or more, a communication error between the forward recognition camera and steering sensor continues for 5 second or more. CAN communication system Radar Cruise2
U012987 Lost Communication with Brake System Control Module Missing Message When the engine switch on (IG) for 2 seconds or more, a communication error between the forward recognition camera and skid control ECU (brake actuator assembly) continues for 5 seconds or more. CAN communication system Radar Cruise2
U015587 Lost Communication with Instrument Panel Cluster (IPC) Control Module Missing Message When the engine switch on (IG) for 2 seconds or more, a communication error between the forward recognition camera and combination meter assembly continues for 50 seconds or more. CAN communication system Radar Cruise2

PROCEDURE

1.CHECK FOR DTCs (Radar Cruise2)
a.

Clear the DTCs.

Click hereEngine / Hybrid System>CRUISE CONTROL>DYNAMIC RADAR CRUISE CONTROL SYSTEM>DTC CHECK / CLEAR

Powertrain > Radar Cruise2 > Clear DTCs
50002 426

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.
