U030000 (Power Operated Tailgate - POT)

Diagnostic trouble code (DTC) information POT-U030000

Condition
The control modules communicate with each other for exchange of information in a network via a standardized serial communication procedure - CAN (Controller Area Network). The Central electronic module (CEM) regularly transmits messages on the CAN network. These messages contain information about which signal configuration ID applies to the vehicle. The control modules on the CAN network have the same signal configuration ID so that they can communicate with each other. The control module compares its configuration ID with the signal configuration transmitted on the control area network (CAN) by the central electronic module (CEM).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The control module's configuration ID differ from the ID that the Central electronic module (CEM) transmits.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Activated control module.

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
- Limited functionality in Power-Operated Tailgate Module (POT).

Possible source
- Incorrect configuration parameter. Power-Operated Tailgate Module (POT) is not intended for this vehicle, it may e.g., be a used control module with another software/hardware.

Fault symptom[s]
