On-Board Diagnostics

Type of diagnosis: 

• Continuous. But interrupted when fault criteria fulfilled and will not restart until next driving cycle.

Enable criteria: 

• Engine running and closed loop active. One multiplicative and one additive adaptation performed.

Fault criteria: 

• Additive adaptation exceeds 5 mg/c.

Dependents: 

• P0115 , P0116 , P0117 , P0118 , P0119 , P0131 , P0132 , P0134 , P0444 , P0445 , P1105  and P1133 .

System reaction to a fault: 

• None.

OK report: 

• Provided fault criteria are not fulfilled during the driving cycle, the OK report will made when the ignition is turned off and before the engine stops. Two other types of OK report can also be made:

  Type 1:  If a diagnostic trouble code has already been stored for the diagnosis and the same running conditions have occurred (coolant temperature above or below 71°C, engine speed +/-375 RPM and load +/-10%).

  Type 2:  If there is no diagnostic trouble code stored for the diagnosis or the same running conditions have not occurred.

Fault handling:  (For more information, see FAULT HANDLING III, OTHER EMISSION-RELATED COMPONENTS AND FUNCTION ).

• Type II.
