On-board diagnosis

Type of diagnosis:

Continuous

Enable criteria:

Battery voltage must be between 10 - 18 V.

Engine running.

Bypass valve active.

Fault criteria:

Bypass valve stuck in closed position. Pulsation in intake manifold during engine braking (when valve should open) is higher than calibrated value. Value based on actual and modelled air mass (throttle position and boost pressure).

Checking the wiring harness

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.
