So that the DTCs test can run correctly, the following sequence must be gone through.

Drive the vehicle out of the workshop and allow the vehicle to stand a while with the engine running, so that the Phone module (PHM) has time to receive a GPS position.
Drive the vehicle back into the workshop.
NOTE: Do not remove the remote key from the start control module (SCU).
Click the VCT2000 symbol and follow the instructions there.

Check that the diagnostic trouble code has disappeared or changed status to intermittent.
