•	CHECK ENGINE.

On-Board Diagnostics

Type of diagnosis:

-	Once per driving cycle.

Enable criteria:

-	Battery voltage should be 10.2-15.8 V.

-	Coolant temperature at start should be between -11 °C and +35 °C.

-	Total fuel quantity since start (within a period of 820-1220 seconds) should exceed 500 cm 3 .

-	P0117, P0118 should not be detected.

-	Speed should be 0-220 km/h.

Fault criteria:

-	Temperature increase is less than 26 °C or greater than 120 °C since start.

Dependents:

-

None.

System reaction to a fault:

-	The control module will continue using the coolant temperature substitute value, -20 °C on start and +60 °C when the engine is running. The following limitations apply: Pedal position sensor adjustable to max 60%

OK report:

-	When the temperature increase has been within the permitted interval.

Fault handling: (See section Fault handling III, other emissions-related components and functions for more information)
