U1000 CAN COMM CIRCUIT
SIDE RADAR LH : Description
CAN COMMUNICATION
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Modern vehicle is equipped with many electronic control units, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN-H, CAN-L) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads the required data only.

ITS COMMUNICATION
- ITS communication is a multiplex communication system. This enables the system to transmit and receive large quantities of data at high speed by connecting plural units with 2 communication lines.
- ITS communication lines adopt twisted-pair line style (two lines twisted) for noise immunity.

SIDE RADAR LH : Diagnosis Procedure
1.PERFORM THE SELF-DIAGNOSIS
1. Start the engine.
2. Turn the BSI system ON, and then wait for 30 seconds or more.
3. Perform "All DTC Reading" with CONSULT-III.
4. Check if the "U1000" is detected as the current malfunction in "Self Diagnostic Result" of "SIDE RADAR
LEFT".
Is "U1000" detected as the current malfunction?
YES - Trouble Diagnosis Flow Chart.
NO - Intermittent Incident.
