Suggested oscilloscope settings are (AC coupling, 1 volt/
div, 100 µsec/div). The signal should be measured on pin
7 of the J560 connector at the nose of the trailer.
PIGTAIL WIRING HARNESSES
Several pigtail wire harnesses are available to connect
the TABS-6 module with ABS and other trailer system
components. Pigtail harness are weather sealed at the
connector interface and are clearly labeled for proper
installation. Because of the over-molded design of the
TABS-6 module wiring harnesses, Bendix recommends that
the complete harness be replaced if damage or corrosion
occurs.
The following connector options may be present:
Modulator 2 (MOD2), Modulator 3 (MOD3), auxiliary,
diagnostic, and additional axle wheel speed sensors.
Note: All TABS-6 modules include the two primary wheel
speed sensor connections and therefore these are separate
from the pigtail harness.
ECU Connectors
Standard TABS-6 module ECU connectors use a TTMA
97-99 5-pin Packard Weather Pack connector for brake
light power, constant power, ground, the trailer-mounted
ABS indicator lamp and a single auxiliary input/output
(I/O).
Premium TABS-6 module ECU connectors use an 18-pin
Deutsch DT series connector for the same function as
above, plus additional modulators, wheel speed sensors
and auxiliary I/O’s.
