Diagnostic Trouble Code (DTC) table 

 

Notes:  

 The following table lists all malfunctions, with the corresponding 5 digit Diagnostic 

Trouble Codes (DTCs) that can be recognized by the Climatronic control module -
J255- and printed out by the VAG 1551 Scan Tool (ST). 

 Malfunctions occurring intermittently are displayed as sporadic malfunctions ("SP").  

 DTC codes appear only on the print-out. 

 The DTC table may also include a description of the type of malfunction.  

 After you made the necessary repairs, always erase the DTC memory and check the 

DTC memory again with the VAG 1551 Scan Tool (ST). 

 If there is a specific complaint and no malfunctions are recognized after checking the 

DTC memory, perform function 03 Output Diagnostic Test Mode (DTM) 

 

Page 01-

 or function 08 Read measuring value block 08 

 

Page 01-43

 . If the display 

flashes but no DTCs were recognized, perform function 07 Code control module and 
then function 04 Basic setting. If necessary, troubleshoot specific complaints using 
conventional methods without OBD 

 Electrical Wiring Diagrams, Troubleshooting & 

Component Locations binder.

malfunctioning (only if Speedometer -
G21- is also not functioning)  

- Replace -G22- 

Cannot be 
checked at 
the moment  

This read-out appears only when the final control diagnosis was 
performed before checking the DTC memory. This DTC will be erased 
from DTC memory when the ignition is switched off. If -G68- is 
malfunctioning , the DTC will reappear when driving.  

1)

 A DTC was found for Speedometer Sensor -G22- and not for Vehicle Speed Sensor -

G68-. The DTC is only recognized if 5 driving cycles take place within 4 minutes after 
starting the engine and no speed signal was measured. A driving cycle consists of start, 
drive over 15 km/h (approx. 9.5 mph), and switch off.
