U1000 CAN COMM CIRCUIT
Description
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with
high data communication speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehicle, 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 line, CAN-L line) allowing
a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.
On Board Diagnosis Logic
- This is an OBD-II self-diagnostic item.
- Diagnostic trouble code "U1000" with CONSULT-III or 17th judgment flicker without CONSULT-III is detected when TCM cannot
communicate to other control units.
Possible Cause
Harness or connectors
(CAN communication line is open or shorted.)
