General Information
Braking with EB
+
In an emergency apply full force on the brake pedal. The EB
+
will be activated immediately you fully apply the brakes
and will assist you to retain steering control of your vehicle according to the road surface conditions. DO NOT apply
and release the brakes by pumping the brake. This is known as 'Cadence braking' and can have a detrimental effect
on vehicle braking.
Lining Wear System (LWS)
EB+ Lining wear is a device that allows multiple lining wear indicatiors (LWI) to be connected to a single analogue
input ‘AUX 4’ on the EB+ ECU. EB+ Lining wear device can be installed on all types of towed vehicles were
provisions are made in the brake pads. The product provides lining wear indication, without the need to remove wheels
as required on disc brakes, via the EB+ diagnostic tools INFO CENTRE or DIAG+.
The device connects to specified sensors from the brake pads and when a brake lining has reached its wear limit the
sensor signals the EB+ Lining wear device which activates the EBS warning lamp indicating a fault.
EB + Stability (2M systems only)
EB+ Stability is an advanced Trailer Roll Stability function that senses when the trailer is near to a rollover
condition and automatically applies the trailer brakes to slow the vehicle combination down. It will help to reduce the
likelihood of trailer rollover BUT IT WILL NOT PREVENT ROLLOVER and should be used as an aid to normal good
driving practice. The stability function is a SAFETY BACK UP system the same as anti-lock braking function.
It uses a lateral accelerometer to determine the level of cornering and as part of its operation it applies brief pulses of
brake pressure during normal cornering, even below a level at which a rollover may occur.
These pulses may be noticeable to a driver but will reduce in number after the system has learnt the vehicle
combinations roll characteristics and are part of the normal operation. This learning process will be repeated every
ignition cycle, if the load is changed or if an axle is lifted or lowered.
Traction Assist using ILAS®-E
On request for traction assist, front axle lifts.
The front axle drops when either :-
•
The vehicle speed exceeds 30kph or
•
The supension pressure reaches more than 130% of the laden bag pressure
Traction assist is made operative by a 24v (constant or intermittent) supply to the yellow wire in the 3 core auxiliary
cable connected to AUX 2 or AUX 3 and programmed as ILAS-E Front.
Pressure switch Installation Option
If the vehicle is being driven when the red line breaks on an EB+ system the REV/TCM will apply the service
brakes via the EB+ valve. If a pressure switch is fitted this can be suppressed until the vehicle comes to
rest, with no pressure switch fitted the brakes will be applied immediately.
The suppression is achieved with an external switch mounted before the REV/TCM, as a comparison can be
made between pressure detected at the EB+ valve and the switch. Pressure at the EB+ valve but not at
the switch means an REV/TCM turnover.
As from August 2004 the Main EB+ assembly incorporates a pressure switch and the installation of an external
pressure switch is an option.
