On-board diagnosis
Type of diagnosis:
Continuous |
Enable criteria:
Ignition ON. |
Battery voltage must be between 11 - 16 V. |
Fault criteria:
When voltage on input below 0.30V for more than 1.0 s. |
Dependent:
None |
System reaction to a fault:
Torque limited to max. 140 Nm. |
Boost pressure adaption blocked. |
The control module uses a substitute value that is a function of atmospheric pressure, engine speed and damper area. |
OK report:
When fault criteria NOT fulfilled for 2 s. |
Fault handling:
Type III |
(See section 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.Diagnostic help
