Diagnostic trouble code (DTC) information SAS-E000

Condition 

Fig 1: Identifying Steering Wheel Control Module

Courtesy of VOLVO CARS OF NORTH AMERICA.

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 on the high speed network (CAN communication blocked).

Steering wheel angle sensor module (SAS) is located inside, and is supplied with power by, the steering wheel module (SWM). Only the steering wheel angle sensor module (SAS) communicates on the controller area network (CAN).

Substitute Value 

• The control module shuts itself off ("bus-off").

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] 

• None.
