Checking The Signal

Activate reading off the voltage level from the Central electronic module (CEM) by clicking the VCT2000 (Volvo Scan Tool) symbol.

If the signal from the Central electronic module (CEM) is less than 1.5 V, there is a short-circuit to ground.

If the signal from the Central electronic module (CEM) is greater than 1.5 V, this is an indication that the fault was present previously but that it is not active at the moment, i. e. the fault is intermittent.
