BODY ELECTRICAL - MULTIPLEX COMMUNICATION
3. Diagnosis
D If a malfunction occurs on the CAN communication line, the ECU that is connected to the CAN
communication line stores the DTC (Diagnostic Trouble Code) in its memory.
D The 5-digit DTC can be read by connecting a hand-held tester to the DLC3.
D The DLC3 is equipped with CAN-H and CAN-L terminals for CAN diagnosis. It is possible to determine
if there is an open or short in the main wire of the CAN No.1 bus by measuring the resistance value between
these terminals.
For details, see the 2007 Camry Hybrid Vehicle Repair Manual (Pub. No. RM02H0U).
Service Tip
The diagnostic communication uses the CAN protocol. Therefore, a hand-held tester and a dedicated
adapter (CAN VIM [Vehicle Interface Module]) are required for accessing diagnostic data. For
details, see the 2007 Camry Hybrid Vehicle Repair Manual (Pub. No. RM02H0U).
