On-board diagnosis
Type of diagnosis:
Enable criteria:
| Battery voltage must be between 11 - 16 V. |
| Coolant temperature greater than 70°C. |
| Motor running more than 180 s. |
| Engine speed between 1500 - 3000 rpm. |
| Air mass between 200 - 500 mg/C. |
| Lambda integrator between 0 - 15 %. |
| Bleeding adaptation more than -10%. |
| Diagnostics for the following components/systems must NOT have reported a fault: |
| • | Crankshaft position sensor |
| • | Shut-off valve, EVAP canister. |
| • | Secondary air injection system (SAI). |
| • | Tank integrity system (EVAP). |
Fault criteria:
| When all conditions are fulfilled, the number of combustion is counted during 4 lambda transitions. |
| Number of combustions exceeds 250. |
Dependent:
System reaction to a fault:
OK report:
| Diagnosis completed without fault report. |
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.
Diagnostic help
