KB4TA D ABS ECU
Doc. No. Y250907 (EN - Rev. 001)
September 2016
The Knorr-Bremse
KB4TA D ECU ES1220
is designed
for air braked trailers (semi-trailers, centre-axle trailers
and full trailers) with mechanical or air suspension.
KB4TA D
is powered via ISO 7638. As an additional safety
feature the ISO 1185 connection is included as standard
so, in the event that there is no ISO 7638 powering, the
ABS function is maintained.
Note: Stop lamp powering should only be considered
as a backup in the event of failure of the ISO 7638
connection.
The
KB4TA D ECU
is designed for all normal system
variants from 2S/2M up to 4S/3M. The configuration
as supplied is 2S/2M for use with two external ABS
modulators (see PD 203-360, Document No.
Y250908
),
but with the integrated auto-configuration the module
detects additional sensors and adjusts upward to 4S/2M automatically. Other configurations and additional functions
can be quickly and effectively achieved using PC Software ECU
talk
®
. For 4S/3M applications an additional external
(third) ABS modulator is necessary (see PD 203-360, Document No.
Y250908
).
Depending on the version, the
KB4TA D
ECU has the option of various auxiliary functions:
–
Odometer/trip counter/service interval
–
Reset to Ride (RtR)
–
Integrated Speed Switch (ISS)
–
ABS Active
–
Brake wear monitoring
–
Stop lamp powering
–
Headboard warning lamp
1)
–
24V output
To ensure fast and effective trouble shooting, the
KB4TA D
ECU can be used with a universal diagnostic interface
which, with diagnostic software ECU
talk
®
, allows connection to a personal computer (PC) for fault diagnosis,
odometer reading and velocity output parameter setting. Alternatively, a diagnostic blink code can be displayed
on the towing vehicle’s “in-cab” and/or the trailer headboard warning light. This can be activated via the stop lamp
supply by depressing the foot brake valve in the towing vehicle. For more information see PD-403-390, Document
No.
Y250910
.
The
KB4TA D ECU
with external ABS modulators is designed to be used as the service replacement part for the
Knorr-Bremse KB3TA, A9 & A18 trailer ABS modules.
1)
The use of a headboard mounted warning lamp is prohibited on vehicles approved to ECE Regulation 13
unless national requirements specifically allow the installation.
