Low
ABS WL
(while
supply
voltage is
detected
as too low)
ABS Wheel
Disabled
ESC/RSC/ATC/
HSA Disabled
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 correct 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.
802 14 5 8 + 5
ECU Central
Ground Open
Circuit
ABS WL
ABS Wheel
Disabled
ESC/RSC/ATC/
HSA Disabled
The ECUs
connection to central
ground has been
interrupted or the
resistance measured
is too high.
• Verify correct ECU central ground (less than 1 ohm resistance).
• Check for corroded, loose or damaged wiring between the ECU and central ground
path.

Internal
Voltage
Supply
ABS WL
ABS Wheel
Disabled
ESC/RSC/ATC/
HSA Disabled
A failure was
detected on the
internal ECU relay 1.
• Measure the battery or ignition voltage supply. Verify voltage is between 9v-16v (12v
system) or 18v-32v (24v system).
• Verify correct 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.
• If all wiring checks are within specs and if fault repeats and does not clear, this may
indicate the ECU has failed.

Continuity between
suspect Active
Braking Valve output
and voltage supply
(short circuit) 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 ABV ground circuit and voltage supply.
• Check for corroded or damaged wiring between the ECU and ABV.
• Fault may indicate an issue with the BPS in certain vintage ECUs, See SID 55 FMI 3.
