System Checking with TECH 1
F0:DATA LIST
If, during the following TECH 1 checks, a nominal value is not attained, the relevant fault diagnosis for the affected circuit is listed under the heading (TECH 1 checking). Before starting actual fault diagnosis, first perform the entire quick check with TECH 1 to gain an overview of which parameters do not lie within the specified tolerances.
Note:
Note that when the control unit has switched over to the emergency mode, the pressure regulator is actuated with approx. 100 mA and the voltage supply is removed from the solenoid valve. The solenoid valves then no longer switch.
At the end of fault diagnosis, erase any trouble codes present and carry out the quick check F0:DATA LIST with TECH 1 listed at the beginning of the diagnostic steps (heading) again, to ensure that the fault has actually been eliminated.
