Description
A switched on valve relay is reported as off (system chip internal status).
Potential Impact
System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.
Set Condition
Erroneous safety logic (Valve relay gate does not switch on or feedback of system chip is wrong), The failsafe logic test switches on the valve relay and checks whether the gate actuation (system chip internally) is possible, If not, this fault is set.
Clear Condition
No internal issue is detected after changing operation cycle. If the condition persists, the DPB module may require replacement.
