Looking for a Lexus ABS pump, brake actuator, ABS actuator, brake booster pump, Skid Control ECU or complete ABS hydraulic unit?
Lexus vehicles use sophisticated electronic braking systems incorporating ABS (Anti-lock Braking System), VSC (Vehicle Stability Control), TRC (Traction Control) and electronic brake control. Lexus hybrid models can use more complex brake actuator, accumulator and brake booster systems.
A failing ABS pump or brake actuator can cause ABS, VSC, TRC and brake warning lights, warning buzzers, hydraulic pressure problems, pump motor faults and diagnostic trouble codes.
At AutoPulse247, we supply genuine used OEM Lexus ABS pumps, brake actuators, brake booster pumps, ABS control modules and complete hydraulic units.
Our stock may include ABS pumps and brake actuators for:
Lexus CT 200h, IS 200, IS 220d, IS 250, IS 300, IS 300h, IS-F, GS 250, GS 300, GS 300h, GS 450h, LS 460, LS 500, LS 600h, RX 300, RX 350, RX 400h, RX 450h, NX 200t, NX 300, NX 300h, UX, ES, RC, LC and other Lexus models.
Different braking systems may be fitted within the same model range. Always compare the complete part number from your original unit before purchasing.
A faulty Lexus ABS pump, brake actuator or brake booster may cause:
A brake actuator or booster pump that operates very frequently even when the brakes are not being used heavily can be an important symptom on some Lexus hybrid braking systems.
Lexus shares many braking-system technologies with Toyota. Exact code definitions can vary by model, year and brake system generation.
Commonly encountered codes include:
C1201 – Engine Control System Malfunction
This code can accompany other engine or vehicle-control faults and does not by itself confirm a defective ABS actuator.
C1241 – Low or High Power Supply Voltage
Indicates abnormal voltage within the brake control system. The 12V battery, charging system, wiring and power supply should be checked.
C1246 – Master Cylinder Pressure Sensor Fault
Can relate to brake pressure measurement, wiring or the brake actuator assembly depending on the system fitted.
C1252 – Brake Booster Pump Motor / Pump Operation Fault
Can indicate a problem associated with brake booster or hydraulic pump operation on applicable Lexus systems.
C1253 – Hydro-Booster Pump Motor Relay / Actuator Fault
May relate to the brake actuator pump motor circuit, relay, electrical supply or actuator assembly.
C1256 – Accumulator Low Pressure
An important Toyota/Lexus braking-system fault. It indicates that the required hydraulic accumulator pressure is not being maintained correctly.
C1391 – Abnormal Leak of Accumulator Pressure
A commonly searched Lexus/Toyota brake actuator fault. It can indicate abnormal loss of hydraulic pressure within the brake actuator/accumulator system.
U0121 – Lost Communication With ABS Control Module
Communication with the ABS/Skid Control ECU has been lost. Possible causes include wiring, CAN communication, power supply or control module failure.
U0415 – Invalid Data Received From ABS Control Module
Another vehicle control module has detected invalid data coming from the ABS/VSC control system.
C1256 and C1391 are particularly important codes on certain Lexus hybrid braking systems.
Typical symptoms may include:
These symptoms can indicate problems involving the brake actuator, accumulator or hydraulic pressure system.
However, correct diagnosis should always be performed before replacing the actuator.
Hybrid Lexus RX models use electronically controlled braking systems that differ from conventional hydraulic brake systems.
Common searches include:
Lexus RX 400h ABS pump
Lexus RX 450h brake actuator
Lexus RX brake booster pump
Lexus RX C1256
Lexus RX C1391
Lexus Check VSC ABS fault
Different generations and production dates can use different brake actuators and ABS components, so the complete OEM part number must be checked.
The Lexus CT 200h is another model where owners may search for brake actuator, ABS pump and accumulator faults.
Symptoms can include frequent pump operation, ABS/VSC warning lights and hydraulic pressure-related diagnostic codes.
Do not purchase a replacement based only on the model. Always match the original part number.
Not necessarily.
ABS, VSC and brake warning lights can also be caused by:
These should be diagnosed before replacing an expensive ABS or brake actuator assembly.
If diagnostics confirm an internal actuator, accumulator, hydraulic pump, pump motor or control module failure, replacement or specialist repair may be required.
Depending on the Lexus model, the braking system can contain several separate components.
ABS Hydraulic Unit – regulates hydraulic pressure to individual brakes.
Brake Actuator – electronically controls hydraulic brake operation and can incorporate valves and pressure sensors.
Brake Booster Pump / Accumulator – creates and stores hydraulic pressure for the braking system on applicable vehicles.
Skid Control ECU – controls ABS, VSC, traction control and related braking functions.
Some Lexus vehicles integrate several of these functions into one assembly, while others use separate components.
Do not choose a Lexus ABS unit based only on:
Model + engine + production year.
Lexus can use several different ABS and brake actuator versions within the same model.
OEM part numbers commonly use Toyota/Lexus formats such as:
44510-xxxxx
44500-xxxxx
47050-xxxxx
47070-xxxxx
Other numbering ranges may be used depending on the component and model.
Units may also carry manufacturer identification from ADVICS, Aisin, Bosch or other OEM suppliers.
Always match the complete OEM number, including all final digits and suffixes.
Two brake actuators can look almost identical but have different hydraulic configurations, electronics or vehicle applications.
Depending on the model, replacement may require:
Hybrid braking systems may require suitable diagnostic equipment to perform the correct bleeding and initialization procedures.
AutoPulse247 supplies genuine used OEM Lexus ABS pumps, brake actuators, brake booster pumps, ABS modules and complete hydraulic units.
Search our store using your:
Lexus OEM part number, Toyota OEM number, ADVICS number, Aisin number, Bosch number, ABS pump number or brake actuator number.
Matching the complete number from your original unit is the safest way to identify the correct replacement.
Send us:
Your Lexus VIN + ABS/VSC fault codes + complete part number + a clear photograph of the label on your original ABS pump or brake actuator.
We can use these details to help identify a suitable replacement from our available stock.
Important: ABS, VSC and brake actuator fault codes are provided for general diagnostic information. Definitions and diagnostic procedures vary between Lexus models and braking-system generations. A fault code alone does not confirm that the ABS pump, brake booster or actuator is defective. Proper diagnostic testing should always be carried out before replacing braking-system components.
