Downloading Software And Replacing The Control Module: Installation
When installing the Alcohol Analyzing Start Inhibitor, the handset unit code/ID is stored in the Central electronic module (CEM). Only one handset unit can be programmed for the vehicle. If the unit were to break or need replacing, a new one can be programmed. The handset unit is programmed via the Software manager in VIDA (Volvo scan tool).
At installation, also select which BYPASS variant the vehicle is to have; emergency function (single) or multiple.
Single BYPASS can only be used once and must then be reset by erasing diagnostic trouble codes from the Central electronic module (CEM).
Multiple BYPASS can be used indefinitely.
