Cannot be 
checked at 
present  

This display appears only if Output Diagnostic Test Mode (DTM) was 
performed and the pressure switch could not be checked (e.g. outside 
temperature below 12 C (53  F) before checking the DTC memory. 
This DTC is erased from the DTC memory after switching ignition off.  

1)

 This malfunction cannot be recognized if the outside temperature is below 12 C (53 
F), or if -G17- and -G89- malfunction. The switch is a three-part switch, the 2 bar/32 

bar switch component is tested, the 16 bar switch component is not.

-J285- is malfunctioning if the ABS 
warning light -K47- or brake system 
warning lamp -K118- indicates this 
DTC and it is also shown in the 
DTC memory-02.  

- Replace instrument cluster. 

  

Short circuit or open circuit in wiring 
or connectors.

module -J255-. Then select the 
following functions one after 
another: 07 Code control module

1)

 This "signal" comes from the control module within the instrument cluster (-J285-). The 

control module -J255- uses this signal after the engine was switched off and restarted 
within 2 hours, to replace the values of the current outside air temperature sensor -G17- 
and fresh air intake duct temperature sensor -G89- with the last operating temperature 
values. The measured values would otherwise be influenced by the radiated heat from 
the stopped (stationary) engine. The ignition off signal only occurs after starting the 
engine.
