System Components: Backlighting
The cluster sends a K-CAN bus signal to other modules on in the vehicle to inform them of backlighting intensity.
While the vehicle lighting is OFF, a phototransister in the instrument cluster graduates the amount of backlighting needed to overcome ambient lighting.
While the vehicle lighting is ON, the backlighting is determined by the adjustment of the KL58g circuit via the BC menu on the cluster. The lighting intensity can be set by using the rocker switch on the turn signal stalk on the steering column.
