Performance loss.

On-board diagnosis

Type of diagnosis:

Continuous

Enable criteria:

Ignition ON.

Fault criteria:

No voltage on the control module output for more than 0.6 s

System reaction to a fault:

Control module uses 100% PWM signal as substitute value for EGR control.
Shut-off damper, motor not working.
The control module uses 0% PWM signal as substitute value for the shut-off flap control valve.

OK report:

Fault criteria NOT fulfilled for 0.6 s.

Checking the wiring harness

Faults in the control module female connector can be the cause of the DTC. Check the connector with respect to oxidation, depressed pins and pin clamping force.
Move the wiring harness at several spots and in several directions to reveal intermittent breaks and short-circuits. Check switches, connectors and crimp connections for oxidation, retracted pins and pin clamping force.

Diagnostic help
