CONCERN
Replacing functional DME control modules unnecessarily due to fault codes in the DME fault memory, whose cause is not the DME control module.
INFORMATION
Test have shown that most DME control modules returned under warranty have fault codes in the DME fault memory not related to a DME control unit malfunction, however faults codes related to other components (e.g., secondary-air pumps).
An overview of the DME fault codes where the DME control module is not the cause for the stored fault code or complaint is enclosed (below) with this Technical Information Bulletin.
The causes for these fault codes must be localized and corrected using troubleshooting procedures according to the Technical Manual, Diagnosis.
The replacement of the DME control module is not a warranty matter in these cases. If it is determined that a DME control module that has been returned under warranty for these unrelated fault codes, the control module will be returned and your account debited.
The fault code overview will be published along with Supplement 14 and 15 for the Cayenne On-Board Diagnosis Manual (OBDII) in September 2004.
LITERATURE
Cayenne On-Board Diagnosis Manual (OBDII):
- DME 7.1.1
UNNECESSARY CONTROL UNIT REPLACEMENT FOR DME 7.1.1
NOTES:
- The following list contains P codes for which the DME 7.1.1 control module can be ruled out as a possible cause for the fault.
- This means that in these cases, replacing a DME control module is not permitted. The fault source must be searched for according to the instructions described in this manual. See the chapter "Possible fault causes" in the Main Chapter "Introduction".
- Again, we would like to emphasize that defective DME control modules are extremely rare! Replacing a DME control module should only be the last resort after all other fault causes have been ruled out!
