Fault symptoms

•	Engine will not start.

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.)

-	Crankshaft rotating. Main relay voltage above 6V.

Fault criteria: (When enable criteria have been fulfilled, diagnostics will check if the fault criteria have been fulfilled.)

-	Voltage on all ignition triggers below 2V for 1s.

Dependents: (Once fault criteria have been fulfilled, a number of other diagnostics must report OK before the diagnostic trouble code can finally be generated.)

-

None.

System reaction to a fault: (Once the fault criteria have been fulfilled, certain measures will sometimes be taken.)

-	Fuel shut-off.

OK report: (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.)

-	Type III. Does not turn on CHECK ENGINE.

Diagnostic help

The diagnostic trouble code is generated when there is no power to the ignition discharge module.

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.
