Pressure Sensors
Erase the fault memory and restart the ECU. If the fault does not exist anymore, wait until the compressor has pumped into the system and the pressure has reached the cut-out threshold. After the compressor has been switched off, the pressure sensor assembly check is carried out. Check the fault memory for this error again. If the fault is present, replace the ECU (and run the configuration service). After the pressure sensors have been configured successfully another execution of the assembly check shall give proof that ECU and pressure sensor assembly are fully functional again.
What you'll see
No driver-visible symptom recorded.
System reaction
Depending on the reason the system pressure calculation might be incorrect (not all pressure values available).
Diagnostic depth
The pressure sensor assembly of the device is checked after each startup to ensure that it is fully functional.
Execution of pressure sensor assembly check failed because the allowed maximum run-time has expired.
