The supply voltage
is temporarily too
low.
• Measure the battery or ignition voltage under load. Verify voltage does not drop below
9v (12v system) or 18v (24v system).
• Verify proper ECU and battery ground (less than 1 ohm)
• Check the vehicle battery and associated components (alternator).
• Check for corroded or damaged wiring between the ECU and voltage supply as well as
ground path.
• Check conditions of fuses.
803 15 5 8 + 5
All ABVs High
impedance
ABS WL
ESC/RSC/ATC/
HSA Disabled
ECU has detected
that the suspect
Active Braking Valve
circuit is not
detected, has high
impedance or the
circuit has been
interrupted.
• Verify 7.0-14.0 ohm between ABV supply and ABV common for 12V system (26.3-49.0
ohm for 24V system).
• Verify if connectors are fully seated, check for corroded or damaged wiring between the
ECU and ABVs.
• Replace ECU if all wiring checks are within spec and if fault repeats and does not clear.

ABS WL N/A
Continuity between
suspect Active
Braking Valve circuit
and ground is
detected.
• Verify 7.0-14.0 ohm between ABV supply and ABV common for 12V system (26.3-49.0
ohm for 24V system).
• Check for continuity between suspect Active Braking Valve circuit and ground.
• Check for corroded or damaged wiring between the ECU and ABVs.
• Replace ECU if all wiring checks are within spec and if fault repeats and does not clear.

A failure was
detected on the
internal ECU relay 2.
• Measure the battery or ignition voltage supply. Verify voltage is between 9v-16v (12v
system) or 18v-32v (24v system).
• Verify proper ECU and battery ground (less than 1 ohm)
• Check for corroded or damaged wiring between the ECU and voltage supply as well as
ground path.
• Replace ECU if all wiring checks are within spec and if fault repeats and does not clear.

shorted to
UBATT
ABS WL
ESC/RSC/ATC/
HSA Disabled
Continuity between
pressure signal
circuit and voltage
supply (short circuit)
is detected. E401
and E404 version
only
• Check for continuity between pressure sensor signal circuit and voltage supply.
• Check connectors and pressure sensor for corrosion.
• It could also be possible that the ECU has detected a permanent braking signal from
the pressure sensor between zero to 30 mph.
• Fault only for E401 and E404 versions only.
1045 16 5 7 + 7
E401 and
E404 version
only. Pressure
Sensor
shorted to
ground
ABS WL
ESC/RSC/ATC/
HSA Disabled
Continuity between
pressure signal
circuit and ground
(short circuit) or an
open circuit is
detected. E401 and
E404 version only
• Verify if connectors are fully seated, check for corroded or damaged wiring between the
ECU and component.
• Check for continuity between pressure sensor signal circuit and ground.
• The pressure sensor supply line could be also clogged or frozen up.
• Call Meritor WABCO OnTrac at 866-OnTrac1 (668-7221) with part number to ensure
ECU is correct for the application.
• Fault only for E401 and E404 versions only.

• Verify 7.0-14.0 ohm between ABV supply and ABV common for 12V system (26.3-49.0
ohm for 24V system).
• Check for continuity between suspect ABV ground circuit and voltage supply.
• Check for corroded or damaged wiring between the ECU and ABV.
