On-board diagnosis

Type of diagnosis:
Continuous

Enable criteria:
Battery voltage must be between 11 - 16 V.
Ignition ON.

Fault criteria:
When the voltage on the input exceeds 4.70 V for more than 1 s.

Dependent
None

System reaction to a fault:
Torque limited to max. 170 Nm.
Tank bleeding adaption is blocked and reset.
Substitution value for atmospheric pressure = boost pressure value (before damper) upon start of engine.

OK report:
Fault criteria NOT fulfilled for 2 s.

Fault handling:
Type III
(See Description of On-Board Diagnostics/Fault handling III, "Other emission-related components and functions" for more information.)

Checking the wiring harness
Move the wiring harness at several spots and in several directions to reveal intermittent breaks and short-circuits. Check switches, connectors and crimp connections for oxidation, retracted pins and pin clamping force.
