If you cannot find any plausible data in the measured values listed above, please check whether the vehicle is
equipped with PR number 5P2 “Rear occupant detection”.

If the vehicle is equipped with this PR number, ask the customer if the occupant detection could have been triggered
instead of the anti-theft alarm.
To help distinguish between the two:

When the occupant detection is triggered, the acoustic warning _is made by the regular horn rather than the anti-theft
alarm horn.
