Looking for a Honda ABS pump, ABS control module, VSA module or complete ABS hydraulic unit?
Honda vehicles use ABS together with VSA (Vehicle Stability Assist), traction control and electronic brake distribution systems. A faulty ABS hydraulic pump or electronic control module can cause ABS, VSA and traction control warning lights, pump motor faults, brake pressure sensor faults and communication problems.
At AutoPulse247, we supply genuine used OEM Honda ABS pumps, VSA modulators, ABS control modules and complete ABS/VSA hydraulic units.
Our stock may include ABS pumps and modules for:
Honda Civic, CR-V, Accord, Jazz/Fit, HR-V, FR-V, Insight, CR-Z, Integra, Legend, Stream, S2000, e:Ny1 and other Honda models.
This includes popular generations such as Civic VIII, IX, X and XI; CR-V III, IV and V; Accord VII and VIII; Jazz/Fit; and HR-V.
Different ABS/VSA units can be fitted to vehicles of the same model and year. Always compare the complete part number from your original unit before purchasing.
A faulty Honda ABS pump or VSA modulator may cause:
Honda uses manufacturer-specific ABS/VSA codes as well as standard communication codes. Exact definitions can vary by model and ABS/VSA generation.
Commonly encountered codes include:
61-1 – Battery Voltage / Power Supply Related Fault
Often associated with low voltage or a power-supply issue. The battery and charging system should be checked before replacing the ABS/VSA unit.
66-1 – Brake Pressure Sensor Fault
On applicable Honda systems, this can relate to the brake pressure sensor or its circuit. Some ABS/VSA modulators incorporate the pressure sensor within the assembly.
81-1 – ABS/VSA Control Unit Related Fault
Can indicate an internal control-unit or system malfunction depending on the model and VSA generation.
84-1 – Steering Angle / Sensor Neutral Position Related Fault
Can occur when sensor calibration or neutral-position learning is required.
121-1 / 122-1 – VSA / Control System Related Faults
Definitions vary between Honda models and should be checked using model-specific diagnostic information.
C0031 / C0034 – Wheel Speed Sensor Circuit Faults
Usually associated with wheel speed sensors, wiring, connectors or wheel bearing encoders rather than the ABS pump itself.
U0121 – Lost Communication With ABS Control Module
Communication with the ABS/VSA module has been lost. Possible causes include CAN Bus wiring, power supply, ground connection or an internal control module fault.
U0415 – Invalid Data Received From ABS Control Module
Another vehicle module has received invalid information from the ABS/VSA control system.
66-1 is an important Honda ABS/VSA code on applicable models.
Possible symptoms include:
Depending on the ABS/VSA system, the brake pressure sensor may be integrated into the hydraulic modulator assembly.
However, wiring, electrical supply and related components should be checked before replacing the ABS unit.
Not necessarily.
A Honda VSA or ABS warning can also be caused by:
A complete diagnostic scan should be carried out before replacing the ABS/VSA modulator.
The Honda Civic is one of the most common Honda models for ABS/VSA replacement units.
Different generations can use multiple ABS systems depending on:
A visually identical Civic ABS pump should not automatically be assumed to be compatible.
Always compare the complete Honda and manufacturer part numbers.
Honda CR-V models can use different ABS/VSA modulators according to generation, engine and drivetrain.
This is particularly important with 2WD and AWD versions.
The ABS/VSA system can interact with the vehicle's traction and all-wheel-drive control systems, so the exact replacement unit should be identified before installation.
Different Honda Accord generations use different ABS and VSA systems.
When replacing an Accord ABS unit, check:
Do not purchase solely based on appearance.
The Honda Jazz, also sold as the Honda Fit in some markets, can use several different ABS/VSA units.
Always compare the original ABS modulator label because units from similar model years may have different electronics or software.
Do not choose a Honda ABS unit based only on:
Model + engine + production year.
Honda ABS/VSA assemblies commonly carry an OEM number in formats such as:
57110-xxxxx
57111-xxxxx
The unit may also carry identification from manufacturers such as:
The exact numbering system varies by model and generation.
Always match the complete OEM part number, including all letters, numbers and suffixes.
Two Honda ABS pumps can look identical but use different electronics, software or hydraulic configurations.
The complete Honda braking-control assembly can contain:
ABS Hydraulic Modulator – controls hydraulic brake pressure at individual wheels.
ABS Pump / Motor – creates hydraulic pressure when required by the ABS/VSA system.
ABS / VSA Electronic Control Unit – processes sensor information and controls ABS, stability and traction-control functions.
Brake Pressure Sensor – on some systems this may be integrated into the modulator assembly.
Depending on the fault, the electronic module, hydraulic section or complete ABS/VSA modulator assembly may require replacement.
Depending on the vehicle, replacement may require:
Suitable Honda-compatible diagnostic equipment may be required after installation.
AutoPulse247 supplies genuine used OEM Honda ABS pumps, VSA modulators, ABS control modules and complete ABS/VSA hydraulic units.
Search our store using your:
Honda OEM part number, Nissin number, Bosch number, ATE/Continental number, ADVICS number, ABS pump number or VSA modulator number.
Matching all available numbers from your original unit is the safest way to identify the correct replacement.
Send us:
Your Honda VIN + ABS/VSA fault codes + complete ABS part number + a clear photograph of the label on your original ABS/VSA unit.
We can use these details to help identify a suitable replacement from our available stock.
Important: ABS and VSA fault codes are provided for general diagnostic information. Exact definitions vary between Honda models and ABS/VSA generations. A fault code alone does not confirm that the ABS pump or VSA modulator is defective. Proper diagnostic testing should always be performed before replacing braking-system components.
