CAN BUS DIAGNOSTICS
As ECUs are connected via CAN bus (including M.U.T.-III), always diagnose CAN bus to confirm its normality when inspecting. Simply by performing M.U.T.-III screen operations, the following inspections can be performed automatically, and the result can be used to verify the CAN bus status.
- Voltage measurement between the CAN_L and CAN_H and the body earthing terminal
- Resistance measurement between the CAN_L and CAN_H
- Confirmation of communication of all ECUs
