Wait until after the modulator chuff test before activating
thebrakelightpower.Alternatively,waitve(5)seconds.
Note: If certain Diagnostic Trouble Codes (DTCs) are set,
typically where modulator DTCs have occurred, the chuff
test may not run.
Following a single display of all available messages, the
ABSindicatorlampwillremainonforvesecondsandthen
return to normal operating mode. Blink code diagnostics
can only be activated following a power‑up, where wheel
speeds have not been detected. If the vehicle moves during
the blink code diagnostics mode, the Bendix
®
TABS‑6
™
Adv
MC module will cancel the blink code diagnostics and return
to normal operating mode.
Blinkcodediagnosticsmustbeactivatedwithintherst15
seconds of ignition power being applied.
If brake light power is continuously applied for greater than
veseconds,blinkcodediagnosticswillbedisableduntil
the next time the ignition power is cycled.
Display Active Diagnostic Trouble Codes (DTCs)
To display active codes, apply ignition power and depress
and release the brake pedal three (3) times within 15
seconds (allowing one second between each application).
Following this activation, there will be a ve (5) second
delay followed by a blink code display sequence of all
active DTCs.  (See pages 13-19 for more information
aboutDTCs.)
Display Inactive Diagnostic
Trouble Codes (DTCs)
TodisplayinactiveDTCs—thosethatarenotcurrentlyset,
buthaveoccurredandarestoredintheECUsmemory—
apply ignition power and depress and release the brake
pedal four (4) times within 15 seconds. Following this
activation,therewillbeave(5)seconddelayfollowedby
ablinkcodedisplaysequenceofallinactiveDTCsstored.
(Seepages13-19formoreinformation.)
Reset Active Diagnostic Trouble Codes
To reset active codes, apply ignition power and depress and
releasethebrakepedalve(5)timeswithin15seconds.
Followingactivation,therewillbeave(5)seconddelay
followed by:
(a)If no DTCs remain, a blink code message of 1-1,
(SystemFullyOperational-NoDTCsDetected)and
theABSindicatorlampwillceasetobeilluminated;or
(b)IfthereareremainingactiveDTCs,asequenceofblink
codeswilldisplayalloftheremainingactiveDTCs,and
the ABS indicator lamp will stay on.
ResettingactiveDTCswithblink codediagnosticsdoes
not clear information from trouble code history. Both blink
code diagnostics or diagnostic tools can retrieve inactive
DTCs,butonlydiagnostictoolscanclearthisinformation.
Display Odometer Mileage
To display the trailer odometer mileage, apply ignition
power and depress / release the brake pedal seven (7)
timeswithin15seconds.Followingactivation,therewill
beave(5)seconddelayfollowedbyablinkcodedisplay
oftheodometerinformation(x1000).
Example:152,431mileswillbedisplayedas:152(x1000)
or1blink(pause);5blinks(pause);2blinks.
Zeros will be displayed by the ABS indicator lamp strobing
twice.
Odometer mileage cannot be altered with blink code
diagnostics. Complete odometer information can be
retrieved using a diagnostic tool.
21. AUXILIARY FEATURES
Rear Axle Suspension Dump
Somespread-axletrailersareequippedwitharear-axle
suspension air bag dump feature to assist with cornering
at low speeds. The TABS‑6 Adv MC module may be
conguredtousethisfeature.Whenthisfeatureisused
belowapre-determinedthresholdvehiclespeed,theECU
will partially exhaust the rear axle air suspension bags, and
thenre-inatethemwhenthevehiclespeedrisesabove
the threshold. For more information about this feature,
contact your local Bendix Account Manager by calling
1-800-AIR-BRAKE(1-800-247-2725).
Lift Axle Control (Automatic)
The TABS‑6
™
Adv MC module can be configured to
automatically raise a lift axle when the load on the trailer
dropsbelowaconguredlevel.Changestothetrailerto
allow for this feature include the use of one of the auxiliary
outputs to operate a lift axle control valve.
