Diagnostic trouble code (DTC) information SAS-E000

Condition

The control modules transmit and receive information via a standardized serial communication method - CAN (Control Area Network). The diagnostic trouble code (DTC) is stored if the control module registers serious interference (CAN communication blocked).

NOTE:

In the event of system communication problems, it is not possible to communicate with the control module. Therefore it will only be possible to read off the fault if it is intermittent.

Substitute Value

The control module shuts itself off ("bus-off").
HINT: The control module will remain shut off until the power supply is broken (15, 30, X). When the power supply is connected the control module will make a new attempt to communicate.

Possible Source

Short-circuit between the control area network (CAN) wiring
Open-circuit in the control area network (CAN) wiring
Internal fault in the control module
Internal fault in another control module in the same part of the control area network (CAN).

Fault symptom[s]

The anti-spin warning lamp is lit
No stability function.
