WARNING: This page is about a different variant/trim than selected.
1. Connect the HDS to the data link connector (DLC) .
2. From the BODY ELECTRICAL SYSTEM SELECT menu, select B-CAN CONTROL UNITS INFORMATION, and then select CHECK CONNECTED CONTROL UNITS. Check that the electronic control units (ECU) are communicating with the HDS.
3. Check that the electronic control units (ECU) are communicating with the HDS.
NOTE:
- If an ECU is communicating with the HDS, "DETECT" will be displayed.
- If an ECU is not communicating, or the vehicle is not equipped with that ECU, "NOT AVAILABLE" will be displayed.
4. If a control unit is not communicating, confirm which ECUs are communicating, then refer to the B-CAN Communication Line from the Electrical Wiring Diagrams to find the malfunction point. For example, when unit "K" is communicating, but units "G", "M", and "N" are not communicating, that will direct you to the malfunction point (A).
