Alcolock (Alcohol Analyzing Start Inhibitor)

Information and verification, Alcolock (Alcohol Analyzing Start Inhibitor)

Symptom and function description
In a vehicle with Alcoguard (Alcolock, Alcohol Analyzing Start Inhibitor) installed, the driver must perform a breath test in the Alcolock's hand unit. If the test is approved (alcohol content less than 0.2 percent alcohol), vehicle start is allowed.
The Alcolock's (Alcohol Analyzing Start Inhibitor) hand unit is located behind the instrument panel in a holder that also functions as a charger. If the hand unit has been securely fastened in the holder, it shall be activated when it is removed. Otherwise it can be turned on with the ON/OFF-button (5).
A test result can be sent from the Alcolock's (Alcohol Analyzing Start Inhibitor) hand unit within a radius of 10 meters from the vehicle. The result from breath test is stored in the Alcolock (Alcohol Analyzing Start Inhibitor) for 30 seconds and can be sent again with the send button (4) on the hand unit. Driver information module (DIM) gives information about what shall be done for the vehicle to start. However, the information is only shown in case of incorrect handling.
If a new start attempt is made within 30 minutes after the engine last was turned off, a new breath test does not have to be performed to enable vehicle start.

Hint: For the Alcolock (Alcohol Analyzing Start Inhibitor) to work correctly for breath test, radio transmitting objects should not be close by.

It is possible to by-pass the Alcolock (Alcohol Analyzing Start Inhibitor), so that the vehicle can be started without an approved breath test, by pressing and holding in the READ-button (located on direction indicator) and the button for hazard flashers at the same time for 5 seconds. When installing the system, choose if it shall be possible to by-pass the vehicle more than once.
In addition to the light-emitting diode (2) which responds to the driver's breath test, there are two light-emitting diodes that show the battery's charge level (1) and if the hand unit is ready for testing (3).
For the Alcolock (Alcohol Analyzing Start Inhibitor) to work, it must be calibrated every year. A message in the Driver information module (DIM) 30 days before last calibration date is shown when calibration is to take place.

Hint: Start problems for vehicles with Alcolock (Alcohol Analyzing Start Inhibitor) do not have mean that the problem is with the Alcolock.

Alcolock (Alcohol Analyzing Start Inhibitor) cannot be used in vehicles with keyless entry system.
