Information Bus: Service and Repair

TROUBLE DIAGNOSTICS WHEN USING DIAGNOSIS TOOL

1. The diagnosis tool supports quick diagnosis of supported body electrical systems through input/output monitoring. and actuation testing.
2. To diagnose the BCM function, select the menu of model and body control module.




3. Select the module menu to diagnose.




4. The CURRENT DATA function is used to monitor input/output conditions.








5. Use the ACTUATION TEST mode to force output devices to operate for testing purposes.








6. Use the "DIAGNOSTIC TROUBLE CODES" mode.






INSPECTION

1. The body network system consists of several ECUs 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.
2. 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.
