Description
Alert in system ASIC: Electric or hyraulic decouple bit not reset automatically.
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
System chip internal decouple bits are not reset within the expected time. The failsafe logic test sets the hydraulic and electric decouple bits of the system chip.
Clear Condition
No internal issue is detected after changing operation cycle. If the condition persists, the DPB module may require replacement.
