Bendix Commercial Vehicle Systems TABS-6 ADVANCED SINGLE CHANNEL - Manual (Page 12)

Wait until after the modulator chuff test before activating
the brake light power. Alternatively, wait five (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 five 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 module will cancel the blink code diagnostics
and return to normal operating mode.
Blink code diagnostics must be activated within the first 15
seconds of ignition power being applied.
If brake light power is continuously applied for greater than
five 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 five (5) second
delay followed by a blink code display sequence of all
active DTCs. (See pages 13-17 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 five (5) second delay followed by
a blink code display sequence of all inactive DTCs stored.
(See pages 13-17 for more information.)
Reset Active Diagnostic Trouble Codes
To reset active codes, apply ignition power and depress and
release the brake pedal five (5) times within 15 seconds.
Following activation, there will be a five (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 five (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 module may be configured
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-inflate 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 module can be configured to automatically
raise a lift axle when the load on the trailer drops below
a configured 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.
