Warning lamp
The warning lamp is used to indicate when a fault has occurred. It can be triggered either by the EB+ CAN Hub
ECU (working as a router or a repeater), or a local or a successor ECU (i.e. another EB+ CAN Hub in the road train,
EBS ECU such as EB+ Gen3). The warning lamp signal goes through pin 5 on EB+ Power A connector.

Lamp indicator
The warning device function depends on the ISO 7638
power supply used:
A warning lamp device located on the driver’s console
of the towing vehicle is operated from the ISO 7638
power cable only when the EB+ Gen3 is powered by
the ignition switch.
If a dedicated power source is unavailable to the
EB+ Gen3 from the ISO 7638 connector then system
integrity will not be indicated by the cab mounted
warning device.
As an option to the cab warning device a trailer
mounted warning lamp may be provided as an auxiliary
function. This lamp mimics the signal to the cab
warning device but will only function if the
ISO 7638 power is connected.
The signal produced by the trailer warning lamp may
be different to that produced by the cab device due to
possible modification of the cab device by the towing
vehicle.
A trailer-mounted warning lamp is not allowed in some
countries
