EBS Diagnostics

EBS diagnostics for silo trailers and semi-trailers: Wabco TEBS G2/G3, Haldex, BPW. Fault code reading, sensor calibration, module repair. PHS Magnum Chorula (A4 Opole).

In Brief

EBS (Electronic Braking System) diagnostics covers Wabco TEBS G2/G3/G4 and Haldex EB+ Gen 2/3 systems. Fault code reading, sensor calibration, module programming. Mobile diagnostics on the A4 within 100 km of Chorula: 45–110 min response. Quotation on request.

Electronic braking systems (EBS) have replaced conventional pneumatic ABS in modern silo trailers. Wabco TEBS G2/G3 or Haldex EB+ is the standard in bulk trailers and cement tankers. An EBS fault is not merely a dashboard warning — it represents a real risk of roadside detention and degraded braking performance, particularly under full load.

PHS Magnum has full diagnostic equipment for EBS systems from all leading trailer manufacturers.

EBS systems — what they are and how they work

EBS electronically controls brake pressure at each individual wheel on the trailer. Unlike conventional ABS, EBS actively adjusts braking force according to axle load, reducing the risk of wheel lockup and ensuring balanced braking.

Key components:

  • EBS central module — the computing and control unit
  • ABS wheel speed sensors — at each wheel
  • EBS modulator valves — control pneumatic pressure
  • Axle load sensor — adjusts braking force to payload
  • Power supply and CAN bus — communicates with the tractor via ISO connector

Computer EBS diagnostics

Full diagnostics covers:

  1. Reading active and historical fault codes (Diagnostic Trouble Codes)
  2. Sensor testing — verifying speed, pressure and load signals
  3. Modulator valve testing — checking correct operation at specified pressures
  4. Calibration — setting parameters for the axle configuration and load
  5. Software update — when replacing a module or changing trailer configuration

Typical EBS faults in silo trailers

Broken ABS sensor cable — the most common fault, especially after winter. Cables at the wheels are exposed to mechanical damage; cores develop cracks. Symptom: fault code on a specific wheel, ABS warning light.

Contaminated or damaged tone wheel — road deposits or rust interfere with speed reading. Cleaning or tone wheel replacement.

Faulty modulator valve — symptom: uneven braking, pressure fault codes. Valve replacement with system recalibration.

Configuration errors after repair — when axles, wheels or other mechanical components are changed, EBS parameters may need updating.

Central module failure — uncommon but costly. Requires reprogramming a new unit with the trailer’s parameters.

EBS repairs — what we do

  • ABS sensor replacement (all wheels and brands)
  • Sensor cable repair and replacement
  • Wabco/Haldex modulator valve replacement
  • EBS central module replacement with programming
  • System calibration after mechanical repairs
  • Parameter update after axle configuration change

Frequently Asked Questions

Wabco TEBS G2, TEBS G3, TEBS G4, Haldex EB+ Generation 2/3, BPW ECO Tronic. Full computer diagnostics with fault code reading, sensor calibration, module programming. We service all trailer brands: Spitzer, Feldbinder, Kassbohrer, Schwarzmüller, Wielton, Krone.

An active ABS or EBS warning light indicates a detected fault in the electronic module or sensors. This can be: ABS sensor fault (broken cable, dirt on the tone wheel), modulator valve fault, module power supply problem, or a parameter outside calibration range. Computer diagnostics displays the exact fault code.

Yes. An active EBS warning light on the trailer is grounds for inspection authority (ITD/Kontrollstelle) to detain the vehicle. The trailer can be taken off the road until the fault is cleared. Typical EBS repairs at PHS Magnum are completed on the same day.

Quotation on request depending on system type and fault scope. Contact us with the trailer make, model year and fault description: +48 602 716 551.

Yes. Our mobile service unit carries a Wabco diagnostic computer. Within 100 km of Chorula on the A4: diagnostics and simple EBS repairs possible on-site. Module replacement usually requires bringing the vehicle to the workshop. Tel: +48 602 716 551.

Diagnostics with fault code reading: 1–2 hours. Sensor calibration and clearing configuration faults: 2–4 hours. ABS sensor replacement: 1–3 hours. EBS central module replacement with programming: 4–8 hours.

Yes. The EBS system is standardised across Europe — Wabco TEBS G2/G3 is the same hardware regardless of registration country. We regularly diagnose DACH-registered trailers passing through the A4 corridor.
