    Hello. The problem is the subject. The abs anti skid service required message is lit. And of course abs don't work. I replaced the pump module and nothing else. I checked on the computer and the error is on the rear right sensor. I also exchanged nothing. Can anyone help?

    No change despite sensor replacement. The mechanic who connected the computer found that after replacing the sensor the error should disappear by itself. It is still lit and abs are not working

    No installation to check, you probably sensed it.

    HOW what, let the electrician fly the beam, change the workshop at all this is the time of diagnosis and you know what and how.
    And if you want to stay with those dazzles, go ahead.

    Yes. Previously, the mechanic connected the diagnostic computer and said so. Right sensor and today I was at a friend's diagnostic station and such errors were. Replacing the sensor did not help with the same errors.

    Then decide whether it was communication or rear sensor or something else.
    And why replace the pump, and in general the same by numbers?

    I checked with a friend at a diagnostic station for the first time and there were such errors as now. But I was also at the mechanic who said that the sensor and exchanged but did not help (diagnostician - diagnostician) the pump has the same numbers.

    I propose to replace the steering retractor
    If this is something I can help in the regeneration of the retractor 721020860 Przemek

    Added after 3 [minutes]:

    The steering retractor, when it is ready for regeneration or replacement, displays the Anti-Skid error and some rashly take on the replacement of ABS sensors and this is not the problem, but most often the retractor needs to be regenerated and put in a regenerated one, if I can help, call 721020860

    I suggest checking the abs crown - it may be cracked.

    Hello guys, something like this has also appeared in my Volvo V70 D5. The problem I have is that I don't know what answer to suggest ....

    None, go to a workshop that embraces Volvo because it's not a simple diagnosis.

Topic summary

✨ The discussion revolves around a 2003 Volvo S60 2.4 D5 experiencing an "ABS anti-skid service required" warning, indicating non-functional ABS. The user replaced the pump module but continues to receive an error related to the rear right sensor, which remains unresolved despite attempts to replace it. Various suggestions include checking the steering retractor, which may need regeneration, and inspecting the ABS crown for cracks. The complexity of the issue suggests that professional diagnosis at a specialized Volvo workshop may be necessary.

FAQ

TL;DR: Case study: 1 persistent right‑rear ABS sensor DTC after replacement; “Pin and read all system errors.” Fixes range from wiring and cracked tone rings to steering retractor faults. [Elektroda, Strumien swiadomosci swia, post #16825732]

Why it matters: This FAQ helps Volvo S60/V70 D5 owners quickly triage ABS/Anti‑Skid faults and choose the next best diagnostic step.

Quick Facts

What does “ABS/Anti‑Skid Service Required” mean on a 2003 Volvo S60/V70 D5?

The ABS module has disabled anti‑lock and stability assistance due to a detected fault. In the thread, the warning stayed on despite an ABS pump swap and pointed to the right‑rear sensor. That means braking works, but ABS and anti‑skid are inactive until the root cause is fixed. [Elektroda, said22, post #16825716]

Will replacing a wheel‑speed sensor clear the ABS light automatically?

It can, but not if the underlying issue is elsewhere. In this case, a new right‑rear sensor did not clear the DTC or the warning. The mechanic expected it to clear itself, yet the fault persisted, indicating another problem such as wiring or the tone ring. [Elektroda, said22, post #16825747]

How do I diagnose a persistent right‑rear sensor fault at home?

Follow three steps:
  1. Scan all systems and note exact DTCs and wheel location.
  2. Inspect sensor connector, routing, and hub area for damage or debris.
  3. Check the tone ring for cracks and test wiring continuity to the module. “Pin and read all system errors.” [Elektroda, Strumien swiadomosci swia, post #16825732]

Could damaged wiring or connectors be the real cause?

Yes. A sensor code can result from open circuits, corrosion, or broken wires between the hub and ABS module. The advice in‑thread was to check the installation (wiring harness) thoroughly before more parts. Movement near the wheel often stresses these wires. [Elektroda, Strumien swiadomosci swia, post #16825773]

What is the ABS tone ring (crown), and how can it fail?

The tone ring is a toothed encoder on the axle or hub that the sensor reads. If the ring cracks or rust swells, the sensor sees erratic signals and triggers ABS/Anti‑Skid warnings. Visual inspection around the CV joint or hub usually reveals splits or missing teeth. [Elektroda, lechr, post #19810688]

Can a bad steering retractor/angle sensor cause an Anti‑Skid error?

Yes. A faulty steering retractor (steering angle sensor assembly) can set Anti‑Skid warnings even when wheel sensors are fine. Regeneration or replacement of the retractor often restores correct stability control inputs. “If I can help in regeneration, call…” reflects this fix path. [Elektroda, przemyslawwojcikowsk, post #19771372]

I replaced the ABS pump/module with the same number. Why no change?

Because the pump was not the root cause. The original poster swapped the pump module and still had the ABS/Anti‑Skid warning and a right‑rear sensor code. Replace only after confirming the module is faulty; otherwise, check wiring, sensor, and tone ring first. [Elektroda, said22, post #16825716]

The scanner shows communication issues. What’s the next step?

Seek a workshop experienced with Volvo diagnostics. Network or multi‑module faults complicate DIY troubleshooting and require VIDA‑capable tools and know‑how. As one reply states, “None, go to a workshop that embraces Volvo because it’s not a simple diagnosis.” [Elektroda, piotrekwoj1, post #21286017]

What is CAN bus in this context?

CAN bus is the in‑vehicle network that lets modules like ABS, ECM, and steering angle sensors exchange data. Faults on CAN can surface as ABS or Anti‑Skid warnings. Think of it as the car’s data backbone for safety and powertrain systems. “Controller Area Network.” [Controller Area Network]

Do ABS faults always clear themselves after a fix?

No. Some clear after a successful repair and short drive. In the thread, the light did not clear after a sensor swap, proving the fix was incomplete. Clear codes only after addressing the actual fault path and confirming live data looks correct. [Elektroda, said22, post #16825747]

What quick checks should I ask my mechanic to perform first?

Ask for: a full‑system scan with freeze‑frame data, visual inspection of the wheel‑speed sensor harness, and verification of the reported wheel location. The expert advice was clear: “Pin and read all system errors,” then proceed methodically. [Elektroda, Strumien swiadomosci swia, post #16825732]

I see multiple different fault suggestions—how do I prioritize?

Start with evidence: the exact DTC and wheel location. Validate sensor power/ground and signal. Inspect the tone ring. Only then consider steering retractor or ABS module. One case logged 1 unchanged DTC after parts swaps, highlighting the need for basic checks first. [Elektroda, said22, post #16825747]

Could a cracked tone ring cause intermittent ABS activation at low speed?

Yes. A split tooth ring can produce dropouts that the module interprets as a locking wheel, often at parking speeds. This presents as pulsation, then the warning stays on. Replacing the damaged ring restores a clean signal. [Elektroda, lechr, post #19810688]

When should I stop DIY and book professional diagnostics?

If codes reappear after sensor replacement, if wiring checks pass, or if scans show network communication errors, stop and book a Volvo‑savvy shop. As one reply notes, this diagnosis is not simple without the right tools. [Elektroda, piotrekwoj1, post #21286017]
