11C400

The lower limit value of component B4/6 (Rail pressure sensor) was dropped below/not reached.


Possible cause:

- Rail pressure sensor offset test
Affected functions:

- Power generation

Test 1: Rail pressure sensor offset test

1. Rail pressure sensor offset test
Rail pressure sensor offset test
Test prerequisites

- Prior to check, the residual pressure in the system must be released by briefly detaching a high pressure line.
- Switch on ignition.
Note

- If a rail pressure reading of over 15 bar is displayed, check the engine control module and the engine wiring harness for output increase (performance tuning).
Communication with ECU required
