Power
System OK - A solid green VLT LED indicates proper
voltage is reaching the module. If no red LEDs are on,
then no DTC's are detected.
If the ABS indicator lamp is on with no red LEDs,
Go To
Section E , page 29.
Voltage Out of Range - A flashing green VLT LED
indicates ECU voltage below 8.0 VDC or above 16.0
VDC. The VLT LED will flash until power is brought into
normal range.
Go to Section F , page 30 .
No Voltage - When the VLT LED is off, the module is
receiving very low or no voltage, or there is no
communication to TRDU. The ECU LED may be on in
this case.
Go to Section F , page 30.
Wheel Speed Sensor DTC
Static DTCs
Dynamic DTCs
The red SEN LED is on to indicate a DTC with a wheel
speed sensor. The example above shows the LEDs
illuminated when there is an additional right sensor
(SAR) DTC.
Troubleshooting and repair are the same for a DTC on
any wheel speed sensor. The indicated sensor DTC
may be static or dynamic.
are related to wiring or component failures
such as open or short circuits.
are related to abnormal wheel speed
signals or behaviors. Go To Section G, page 31 .
ABS Modulator DTC
Static DTCs
Dynamic modulator DTCs
The red M1, M2 and/or M3 LED is on to indicate a DTC
with an ABS modulator. The example above shows the
LEDs illuminated when there is a DTC for a second ABS
modulator (MOD2).
The indicated modulator DTC may be static or dynamic.
are related to wiring or component failures
such as open or short circuits.
are related to abnormal
wheel speed behaviors during ABS.
Go to Section H , page 32 .
ECU DTC
The red ECU LED is on to indicate a DTC internal to the
TABS-6 module. Reset the TRDU tool with a magnet. If
the DTC returns, replace the module.
If the red ECU LED is on and the green VLT LED is off,
the module may have very low voltage. In this case,
go
to Section F, page 30.

Magnetic Reset - All LEDs will be on
while a magnet is held in place at the
RESET location near the “B” in Bendix.
When held for less than 6 seconds, the
DTCs are cleared. When held for more
than 6 seconds, the ABS configuration is
reset. If one or more LEDs do not illuminate,
replace the TRDU
™ tool. Do not reset the
DTC codes until troubleshooting of the
indicated component is complete.
Odometer Mileage - The TRDU will
continously display the odometer
information (x1000) by flashing the
blue ODO LED. There will be a 20
second pause between ODO displays.
As an example: 152,431 miles will be
displayed as:
152 (x1000) ... or 1 blink (pause), 5
blinks (pause), 2 blinks.
Zeros are displayed by the blue ODO
LED
