SAE J1939
Data Link
ESC1

ATC WL ESC Disabled
The electronic
steering control
message (ESC1) is
expected but is not
being received in
expected time or not
at all.
• Verify J1939 wiring between external ECU which is sending request and J1939
backbone.
• This message is most likely to come from a steering tag axle controller.

Disabled
ESC/RSC/ATC/
HSA Disabled
A supply voltage
which is too high has
been measured by
the ECU for more
than 5 seconds.
• Measure the battery or ignition voltage under load. Check the vehicle battery and
associate components (alternator).
• Check the battery and ensure it is correct for the ECU, i.e., ensure a 24V battery is not
being used with a 12V ECU.
• Check for corroded or damaged wiring between the ECU and voltage supply as well as
ground path.

The ECU memorized
system is not in
accordance with the
harness. There are
loads detected at
outputs which
should be open
circuits. Wheel
parameters (number
of tone ring teeth or
tire size) are out of
tolerance.
• Check number of sensors, modulators, 3/2 valves and other components match ECU
configurations.(Parameters and installed components are not matching).
• Verify the installed wheel size matches ECU wheel parameter.
• On E452 ECUs with tire data available on request: check Engine ECU, availability of
engine data information and communication between Engine ECU and the ABS ECU.
• Call Meritor WABCO OnTrac at 866-OnTrac1 (668-7221) with part number to ensure
ECU is correct for the application.

have been
disconnected during
active diagnosis or
programming.
• 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).

The ECU memorized
system is not in

• Check number of sensors and modulators and correct wiring compared to ECU type.
• Call Meritor WABCO OnTrac at 866-OnTrac1 (668-7221) with part number to ensure
ECU is correct for the application.

vehicle.
• Contact vehicle OEM to obtain correct ECU part number for vehicle.
• Call Meritor WABCO OnTrac at 866-OnTrac1 (668-7221) with part number to ensure
ECU is correct for the application.
