1.1.1.1. How do I quickly reach my goal?

How do I quickly reach my goal?First call up menu item 'Evaluation of CAN fault codes' in case of CAN timeout fault codes and communication

errors.The resulting tests must be performed.Menu item 'Further CAN test options' should only be called up if the above-specified tests do not

produce the desired result.Note:Menu item 'General test information' can be called up for an explanation of the different CAN fault types.

1.1.1.2. General test information

Notes on CAN fault codes:CAN timeout fault

- A CAN timeout fault code is set due to the absence of a CAN input signal.The cause of this may be not only the transmitter control unit, but

also the CAN networking.

- For example:No CAN message was received from control unit A.

Bus OFF fault

- A Bus OFF fault code is set, when the control unit cannot send a certain amount of messages to the CAN bus or the messages are

incomplete.The control unit then switches off for a short time from CAN bus.

- For example:CAN controller: CAN bus OFF

Functional CAN fault

- A functional CAN fault code is set because of an implausible CAN input signal.The cause of this is not the CAN networking, but the

transmitter control unit or its sensors.

- For example:CAN signal 'A' from control unit B is implausible.
