15. POWER‑UP SEQUENCE
At power‑up, the TABS‑6 Adv module performs a series of
self‑checks that can assist a technician to determine the
ABSsystemstatusandconguration.
Trailer ABS Indicator Lamp
Atpower-up,withnodetectedDiagnosticTroubleCodes
(DTCs),the trailerABSindicator lampwill illuminatefor
approximately two (2) to six (6) seconds as a bulb check
and then turn off. See Figure 9.
If any active ABS‑ or TRSP‑related diagnostic codes
are present, the trailer ABS indicator lamp will remain
illuminated.
For non-ABS orTRSP-related DTCs, such as auxiliary
functions, at power‑up the trailer ABS indicator lamp will
turn on for approximately six and a half (6.5) seconds as
an extended bulb check and then turn off.
IfaPLC-readytowingvehicleandtrailerarepoweredat
the same time, the TABS‑6 Adv module will also trigger a
bulb check on the dash‑mounted trailer ABS indicator lamp.
Modulator Chuff Test at Power‑Up
At power‑up, the TABS‑6 Adv module activates a modulator
chuff test. This electrical and pneumatic ABS modulator
test can help the technician identify problems with modula‑
tor installations and/or wiring.
With brake pressure applied, a properly installed modulator
will cause two rapid audible chuffs of air pressure. The
TABS‑6 Adv module will not perform a modulator chuff test
withanactiveABSDTC.
*Some vehicle manufacturers may illuminate the trailer ABS
indicator lamp atpower-up regardless ofwhether a PLC
signalisdetectedfromthetrailerornot.Consultthevehicle
manufacturer’s documentation for more details.

16. ODOMETER FUNCTION
Odometer
The TABS‑6 Adv module includes an odometer function
to provide a means of storing the accumulated mileage of
the vehicle. The mileage is computed by using information
received from the vehicle wheel speeds sensors.
Thisfeature isaccurateto within0.62miles perpower-
upandwilltypicallystoremileageupto1,000,000miles.
The mileage can be displayed using PC diagnostics,a
Bendix
®
Trailer Information Module, Bendix

DiagnosticUnit(TRDU
™
), or through blink codes.
Whenever the TABS‑6 Adv module is towed using a pre‑
1997 tractor (with no constant power supplied to the trailer),
no information about mileage will be stored during that
time, and the mileage can be considered out‑of‑calibration.

thetripmileage.ThefeaturecanbeaccessedusingPC

Service Interval
The TABS‑6 Adv module provides a feature that can be
used to indicate a service interval for the trailer. The service
intervalcanbeaccessedusingPCdiagnosticsortheTrailer
