19. High Beam Indicator

The instrument cluster controls the blue colored high beam indicator on receipt of a high beam status message on the medium speed CAN bus from the CJB. The lighting switch on the LH steering column multifunction switch is connected to the instrument cluster. High beam or flash selections using this switch are detected by the cluster which requests the light operation via a CAN message to the CJB. The CJB responds with a high beam active message and the cluster illuminates the high beam indicator. The high beam indicator is not subject to the 3-second indicator check when the ignition is switched on.
