Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition

Note! This diagnostic trouble code (DTC) status is an event controlled diagnostic trouble code (DTC). An event controlled diagnostic trouble code (DTC) does not mean that there is a fault in the control module when it is active, but is designed as information. These diagnostic trouble codes (DTCs) do not need to be erased but disappear when the conditions no longer apply.

The Suspension module (SUM) continually receives information from the Steering wheel angle sensor module (SAS) via CAN communication.
Information is checked by the Suspension module (SUM).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- A message indicating that steering angle or steering wheel angle speed from the Steering wheel angle sensor module (SAS) is incorrect or invalid.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position II.
- The test is carried out every other operating cycle. The Suspension module (SUM) defines an operating cycle as ignition on and ignition off.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.

Note! When diagnostic trouble codes in the suspension module (SUM) are erased, they do not disappear until the next operating cycle (ignition off - ignition on).
