Test sequence
- Switch ignition off.
- Disconnect connector from Recirculating valve for turbocharger -N249-.







- Measure resistance between terminals of valve.
Specified value: 25 to 35 ohms

If specified value is not obtained:
- Replace Recirculating valve for turbocharger -N249-.

If specified values are obtained:
- Connect test box to control module wiring harness, connect test box for wiring test. Test Box, Connecting For Wiring Test







- Check wire between test box socket 105 + 2-pin connector terminal 2 for open circuit according to wiring diagram.
Wire resistance: max: 1.5 ohms
- Check the wire for short circuit to B+ and Ground (GND).

If no malfunctions are found in wire:
- Check wire between 2-pin connector terminal 1 and the Fuel Pump (FP) Relay -J17- for open circuit according to wiring diagram.
