Remove the crash pad lower panel (A).
(Refer to the Body group - crash pad)
The body network system consists of several Modules that communicates via a CAN bus. The diagnostic tester is not directly connected to the CAN bus, but utilizes a one-wire communication line (K-line) that connects to a gateway in the IPM ECU.
The IPM communicates with the diagnostic tester directly. But other units operate self diagnostic, input/output monitoring and actuator operation via the IPM using the CAN communication.
