The ECU detects
that no modulators
are connected. This
is a common fault
during end of line
testing or
programming if only
the X1 connector is
connected.
• Check harness to ensure that modulators are connected and check fuses.
629 254 8 7 + 1 Excessive Slip ABS WL
ABS Wheel
Disabled
ESC/RSC/ATC/
HSA Disabled
One axle is detected
to be rotating much
faster than another.
This fault is common
if vehicle has been
on a dyno and
detection is not
disabled via
diagnostic
command. It is also
possible that there
are excessive
sensor air gaps on
multiple wheel ends.
• Use the “Disable ATC” diagnostic command when the vehicle is on a Dyno.
• Check for excessive ABS sensor gap on multiple wheel ends.

An ABS modulator
was activated for an

• Adjust wheel sensor to touch tone ring.
• Check condition of ABS sensor head.
• Check for loose wheel bearings or excessive hub runout.
• Check mounting of ABS tone ring and condition of teeth.
• Check condition and retention of ABS sensor spring clip.
• Check ABS sensor cable routing and clipping.
629 254 12 8 + 3 Internal Error ABS WL
ABS Wheel
Disabled
ESC/RSC/ATC/
HSA Disabled
There are multiple
causes. Valves may
have been activated
too long during
diagnostic testing.
Internal ECU
communication is
not correct.
• Reset ECU by cycling the ignition or by using the reset option in TOOLBOX™.
• If fault persists, contact Meritor WABCO OnTrac at 866-OnTrac1 (668-7221).
629 254 13 8 + 6
Accelerometer
Out of Range
ABS WL RSC Disabled
The measured
lateral acceleration
by the ECU is out of
range.
• Verify that the ECU is securely mounted, leveled and in correct location as per OEM
specification.
• Reset ECU by cycling the ignition or by using the reset option in TOOLBOX™.
• Call Meritor WABCO OnTrac at 866-OnTrac1 (668-7221) with part number to ensure
ECU is correct for the application.

Not Plausible
ABS WL RSC Disabled
The measured
lateral
acceleration is not
plausible or the
learned offset is too
high. ECU may be
mounted incorrectly.
• Verify that the ECU is securely mounted, leveled and in correct location as per OEM
specification.
• Reset ECU by cycling the ignition or by using the reset option in TOOLBOX™.
• Call Meritor WABCO OnTrac at 866-OnTrac1 (668-7221) with part number to ensure
