Alcohol Analyzing Start Inhibitor, Continued: Overview
In a vehicle with an Alcohol Analyzing Start Inhibitor installed, the driver must provide a breath sample into the Alcohol Analyzing Start Inhibitor handheld unit in order to be able to start the vehicle. If the test is approved (alcohol content lower than the country's statutory blood-alcohol content limit) and an approved remote control key is used, the central electronic module (CEM) permits the vehicle to be started.
The Alcohol Analyzing Start Inhibitor communicates with the Remote Receiver Module (RRX) wirelessly, just like the vehicle's remote keys. The Remote Receiver Module (RRX) transmits information to the Central electronic module (CEM) via LIN. The Central electronic module (CEM) then communicates via the CAN network with the Driver information module (DIM) and the Engine control module (ECM).
The Alcohol Analyzing Start Inhibitor cannot be used in vehicles with keyless entry.
