When voltage on output is below 5.5V when inactive or exceeds 5.5V when active. |
Dependent:
System reaction to a fault:
Fuel adaption is blocked. |
OK report:
Fault criteria NOT fulfilled for 2 s. |
Fault handling:
(See section Fault handling III, "Other emission-related components and functions" for more information.) |
Checking the wiring harness
