On-Board Diagnostics
Type of diagnosis:
|
-
|
Continuous. However, it is interrupted once the fault criteria have been fulfilled and does not restart until the next driving cycle.
|
Enable criteria:
(Conditions that must be fulfilled for diagnostics to be performed.)
|
-
|
Global conditions for this diagnostic trouble code: When starting the engine, the atmospheric pressure must exceed 78 kPa and the temperature of the coolant and the intake air must exceed -7°C.
|
|
-
|
Engine running for at least 3s. Brake pedal not depressed. Vehicle speed above 30 km/h. Engine speed above 500 rpm. Coolant temperature exceeding 60°C.
|
Fault criteria:
(When enable criteria have been fulfilled, diagnostics will check if the fault criteria have been fulfilled.)
|
-
|
Crankshaft position is lost. The criteria must be fulfilled on two separate occasions during the same driving cycle.
|
Dependents:
(Once fault criteria have been fulfilled, a number of other diagnostics must report OK before the diagnostic trouble code can finally be generated.)
|
-
|
P1576, P1577, P0501 and P0502.
|
System reaction to a fault:
(Once the fault criteria have been fulfilled, certain measures will sometimes be taken.)
(This diagnosis may be included as a dependent to another diagnosis and must therefore report OK even if it is continuous. The OK report is also used in fault handling to count down the fault counter.)
|
-
|
Enable criteria fulfilled. Fault criteria not fulfilled within 60s.
|
Fault handling:
(Refer to section “Fault diagnosis, general” for more information.)

Check the wiring
Jiggle the wiring harness at several points and in different directions to check if there are intermittent breaks and short-circuits in the leads. Observe the multimeter, test lamp or diagnostic instrument during the test.
