• Ignition off
• Reconnect the connectors, reinstall components etc.
• Test drive the vehicle on the road. Ensure that high boost pressure is reached (high load) so that the engine control module (ECM) can run the diagnostic.
• Connect the VCT2000 (or appropriate scan tool) to the data link connector (DLC) without switching off the engine.
  NOTE:

  If the engine is switched off, the stored fault status will be erased and the test drive will have to be repeated.

  Read off the diagnostic status and fault status for the diagnostic trouble code (DTC) by selecting the relevant diagnostic trouble code (DTC) from the list.

  Check the fault status for the diagnostic trouble code (DTC) when the diagnostic is "Complete". If the diagnostic is not complete after the test drive, further test driving is required. If the function is correct, the fault status must be "No fault found" when the diagnostic is complete.
