Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information PAM-E001

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 parking assistance module (PAM) registers serious interference on the low speed network (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 diagnostic trouble code (DTC) if the fault is intermittent.

Substitute value
- Parking assistance module (PAM) 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 information lamp is lit
- Message in the display.
