unplanned fleet downtime costs thousands of dollars per vehicle per day

Garrett Early Warning System (EWS) uses the data from your vehicle combined with Garrett’s advanced analytics capabilities to assess your vehicle health and predict when your vehicle will fail.

EWS can analyse all your vehicles systems and subsystems including key systems frequently causing vehicle downtime and cost escalation including:

  • Early detection of Fuel, Exhaust & Aftertreatment or EGR system issues
  • Early detection of airpath issues.
  • Early detection of Battery, Alternator or Relay degradation
  • Brake pad replacement warnings with estimated remaining days and running distance (km)

Whilst running EWS on test fleets EWS signaled undetected issues up to 90 days before failure and up to 21 days before the vehicle emitted a diagnostic trouble code.

EWS analyses data from the vehicle telematics and identifies a problem in the vehicle behavior in near real-time. An anomaly can be detected due to a change in the behavior of a mechanical part or a change in fluids such as in pure fuel.

EWS pinpoints the issue location, notifies the fleet manager and stores the data history for easy visualization in the garage. Real time fault diagnostics reduces the need to replicate the fault increasing first time fix and reducing time off the road.

Driver and vehicle behavior is analyzed using Physics based models (PBM), Artificial Intelligence (AI) and Machine Learning enabling fault prediction from 2 up to 90 days before a critical fault. Reduce unplanned downtime through scheduled maintenance.

EWS compiles a full fault and DTC history including the ability to produce reports of vehicle behavior at the time of the fault. Instantly compare pre and post-fix data. EWS also provides follow-up on the repair and produces the evidence in case of a wrong or failed repair.

Early Warning System Frequently Asked Questions

Q: If I buy the EWS Solution from Garrett, will I also need hardware?
Q: Who is the ideal user for EWS, the Garage or fleet manager?
Q: Does Garrett build the hardware dongles?
Q: Will my Choice of hardware impact the quality of the EWS solution?
Q: Will the EWS system allow for remote changes?


This depends on the telematics capability – if they allow to write we can overwrite to change anomalies on the EWS Platform

Q: Is EWS Compatible with all vehicles?


Yes. EWS can connect to OBD2 as well as singles from trucks and trailer units (J1708 & J 1939)

Q: How does Garrett Manage personal data?


Personal data is only used to give the fleet manager visibility on their fleet and is not shared. When the service ends or upon request all personal vehicle data will be erased. Garrett gathers anonymous data from the vehicle to enable predicative modeling. This data is not personalize and can not lead to the identification of a specific vehicle or individual.

Q: How is EWS different to DTC (Diagnostic Trouble Code) decoding?


DTCs arise when the vehicle ECU has identified an error. DTC decoding will notify the user of an impending error. Through EWS the fleet manager will be notified of potential risks before the DTC is being detected, enabling for more time to schedule the vehicle for maintenance at the most optimal time.
