On-board diagnosis

Type of diagnosis:

Once per driving cycle.

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 status 0.
Lambda integrator between 0 - 15 %.
Bleeding adaptation more than -10%.
Diagnostics for the following components/systems must NOT have reported a fault:
Mass air flow sensor
Crankshaft position sensor
EVAP Valve
Shut-off valve, EVAP canister.
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:

None

System reaction to a fault:

None

OK report:

Diagnosis completed without fault report.

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.
