Iveco ABS Pumps and Control Modules

Iveco ABS Pump – Hydraulic Unit and Electronic Controller

An Iveco ABS pump is part of the anti-lock braking system used to control brake pressure during situations in which a wheel is approaching lock-up. A complete unit normally combines a hydraulic block, electric pump and an electronic ABS controller.

In commercial vehicles such as Iveco, the ABS system works together with wheel-speed sensors and other vehicle electronics. Depending on the model and system version, the same hydraulic assembly can also support additional braking or stability-control functions.

How to choose the correct Iveco ABS pump

ABS units should primarily be identified by the numbers on the original assembly rather than by the vehicle model alone.

Before ordering, compare:

• Iveco OEM number,
• Bosch hydraulic pump number,
• ABS electronic controller number,
• all final digits and suffixes,
• vehicle model and production year as supporting information.

Two ABS pumps can look almost identical and use similar connectors while having different hydraulic blocks, electronic controllers or vehicle configurations.

A similar housing is therefore not sufficient to confirm compatibility.

Bosch ABS pumps for Iveco

The current Iveco ABS category contains several Bosch ABS pump and controller assemblies.

Examples include:

• 0265219441 / 500370968 / 0273004326,
• 0265231895 / 504182309 / 0265800607,
• 0265233377 / 504346590 / 0265900371,
• 0265234130 / 504065619 / 0265950366,
• 0265234748 / 0265951233,
• 5802365327 / 0265280127 / 0265956519.

The Bosch numbers belong to different ABS generations and should always be compared in full.

Iveco 500370968 – Bosch 0265219441 / 0273004326

One of the available units is the Iveco ABS pump and control module 0265219441 / 500370968 / 0273004326.

The main identifiers are:

• Bosch 0265219441,
• Iveco 500370968,
• ABS ECU 0273004326.

This is a good example of why all three references are useful. The Iveco number identifies the vehicle-specific part while the Bosch numbers identify the hydraulic and electronic components of the ABS assembly.

Iveco 504182309 – Bosch 0265231895 / 0265800607

Another version in the catalogue is the Iveco ABS pump 0265231895 / 504182309 / 0265800607.

Important references:

• 0265231895,
• 504182309,
• 0265800607.

When replacing this type of assembly, both the hydraulic-unit number and the electronic-controller reference should be checked.

Iveco 504346590 – Bosch 0265233377 / 0265900371

The catalogue also includes the Iveco 504346590 ABS pump with Bosch 0265233377 / 0265900371.

The complete combination is:

• 0265233377,
• 504346590,
• 0265900371.

Searching for all of these numbers together gives a much more precise result than searching only for an Iveco ABS pump.

Iveco 504065619 – Bosch 0265234130 / 0265950366

Another confirmed product is the Iveco ABS pump 0265234130 / 504065619 / 0265950366.

Important numbers include:

• 0265234130,
• 504065619,
• 0265950366.

The complete number combination should be compared with the original assembly before installation.

Iveco 5802365327 – Bosch 0265280127 / 0265956519

A newer reference currently listed in the Iveco category uses the following numbers:

• Iveco 5802365327,
• Bosch 0265280127,
• Bosch 0265956519.

This unit belongs to a different Bosch number generation than older 02652... / 027300... assemblies, making exact number verification especially important.

Hydraulic pump number vs ABS ECU number

A complete ABS assembly can carry several different references because the hydraulic block and electronic controller are separate parts of one combined unit.

For example:

• 0265219441 – hydraulic ABS unit reference,
• 500370968 – Iveco OEM reference,
• 0273004326 – electronic ABS controller reference.

Another assembly may instead use:

• 0265234130,
• 504065619,
• 0265950366.

This is why one partial number should not be used as the only compatibility criterion.

Common symptoms of an Iveco ABS system fault

Possible symptoms may include:

• ABS warning light,
• brake-system or stability warning messages,
• ABS function unavailable,
• loss of communication with the ABS controller,
• intermittent ABS communication,
• pump motor fault codes,
• hydraulic valve fault codes,
• wheel-speed related faults.

These symptoms do not automatically mean that the ABS pump itself is faulty.

ABS warning light – is the pump always faulty?

No. Before replacing the pump or controller, the braking system should be diagnosed properly.

Other possible causes include:

• wheel-speed sensor failure,
• sensor wiring damage,
• damaged wheel bearing or encoder ring,
• poor power supply or ground,
• fuses and relays,
• corroded electrical connectors,
• CAN communication faults.

Diagnostic trouble codes and live wheel-speed data can help determine whether the fault is in the pump, controller or another part of the system.

No communication with the Iveco ABS controller

If diagnostic equipment cannot communicate with the ABS module, check:

• constant power supply,
• ignition supply where applicable,
• ground connections,
• fuses,
• electrical connector condition,
• damaged or corroded pins,
• CAN communication wiring.

A failed electronic controller can cause loss of communication, but the same symptom can also result from a vehicle-side electrical fault.

Can only the electronic ABS controller be replaced?

In some Bosch ABS systems, the electronic controller can be separated from the hydraulic block. Whether this is appropriate depends on the exact ABS system and the location of the fault.

If you need only the electronic section rather than the complete hydraulic assembly, see our ABS / ESP / ASR control units.

The electronics and hydraulic section must still be correctly matched.

Does an Iveco ABS pump require coding?

Not every Iveco ABS pump uses exactly the same replacement procedure.

Depending on the vehicle and ABS generation, installation may require:

• coding or configuration,
• basic settings,
• calibration of related sensors,
• diagnostic fault-code clearing,
• ABS hydraulic bleeding procedure.

Other systems may require fewer procedures. Coding or VIN adaptation should therefore be confirmed for the exact vehicle rather than assumed for every Iveco ABS pump.

Does the brake system need bleeding after ABS pump replacement?

If the hydraulic brake circuit has been opened during replacement of the complete ABS pump, the system must be correctly bled before the vehicle is returned to service.

On some ABS systems, diagnostic equipment can be required to activate the pump or internal valves during the bleeding procedure. The exact process depends on the vehicle and ABS generation.

How to search for an Iveco ABS pump by part number

The most useful searches combine the Iveco OEM number with the Bosch hydraulic and electronic references.

Examples:

• Iveco ABS pump 500370968 0265219441 0273004326,
• Iveco ABS module 504182309 0265231895 0265800607,
• Iveco ABS pump 504346590 0265233377 0265900371,
• Iveco ABS control unit 504065619 0265234130 0265950366,
• Iveco ABS pump 0265234748 0265951233,
• Iveco ABS pump 5802365327 0265280127 0265956519.

Exact-number searches are much more precise than searching only for “Iveco ABS pump”.
