Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information DEM-U041568

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.

The control modules transmit and receive information via a standardized serial communication method - CAN (Control Area Network). If a control module registers a fault, the control module can then transmit a signal informing that its information cannot be trusted.
The diagnostic trouble code (DTC) is stored if the control module detects:
- The signal that indicates that the information from the brake control module (BCM) is incorrect.
- Incorrect value lasts longer than 10 seconds.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position II.

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.

Substitute value
- Reduced function of four-wheel drive.

Possible source
- Look for the cause of the fault in the brake control module (BCM).

Fault symptom[s]
- 4-wheel/all wheel drive/Does not work
