On-board diagnosis
Type of diagnosis:
Enable criteria:
| Battery voltage must be between 11 - 16 V. |
Fault criteria:
| When voltage on input exceeds 4.85V for more than 1.0 s. |
Dependent:
System reaction to a fault:
| Torque limited to max. 170Nm. |
| Correction of intake air temperature for ignition timing blocked. |
| Substitute value for intake air temperature is current coolant temperature up to +40°C. If coolant temperature exceeds +40°C, the substitute value is +40°C. |
OK report:
| Fault criteria NOT fulfilled for 2 s with engine running. |
Fault handling:
| (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.
