DIAGNOSTIC TOOL: ELECTRICAL ERRORS
P0410 Secondary air valve control
Electrical diagnosis:
•
short circuit to positive / short circuit to negative / open circuit
Error cause:
•
Short-circuit to positive: Excessive voltage detected on PIN 43 of the 7SM control unit.
•
If shorted to negative/open circuit: no voltage has been detected. The instrument panel
indicates this error by lighting up in a fixed manner the MI warning light.
Troubleshooting:
•
Short-circuit to positive: disconnect the component, set the key to ON, start the vehicle and
check if the error symptom is still "shorted to positive": it means that short circuit is between
black/white cable and a cable in voltage, therefore restore cable harness; if the error symp-
tom is short circuit to ground, it means that short circuit is inside the valve and therefore,
you must replace the component.
•
If shorted to negative or open circuit: check the component connector and control unit con-
nector: if not OK, restore; if OK, check the continuity of the black/white cable between the
two connectors: if not OK, restore wiring harness; if OK, with key ON, check if there is voltage
on PIN 1 of the actuator: if there is not voltage, check orange/green cable; if there is voltage,
check component electrical characteristics and replace the component
