Ignition on.
Read off the Geartronic status by clicking on the VCT2000 symbol in VIDA (Volvo scan tool).
Depress the brake pedal. Move the gear selector to the position for manual shifting and check that the status changes.
Move the gear selector lever to +. Check that gear selection is updated in the display in the diagnostic tool as well as the display in the combined instrument panel.
Then move the gearshift selector toward both + and -, and check that the value has been updated in the driver information module's display window.
If the value is updated in the driver information module display, the fault is intermittent. That is to say, it occurred earlier but is not active right now.

If gear selector position is not updated, replace the gear selector module (GSM).
