What's wrong?
The alternator on 2014-2015 Van Hool TD925 and TDX25 coaches turns engine power into electricity. It keeps the batteries charged and supplies power for lights, controls, and other coach systems while the Cummins diesel engine is running. The engine idle setting matters because it controls how fast the engine turns when the coach is stopped.
On affected coaches, the low idle speed was set at 650rpm, which is below the corrected setting of 700 rpm. With the engine idling at that lower speed and the electrical system under maximum load for a prolonged period, the alternator can reach its thermal limit. Heat inside the alternator can then cause a short circuit and alternator failure.
There is no warning sign before failure. The first clear sign can be an alternator failure or a fire suppression system activation after the alternator overheats.
Who's affected?
The TD925 appears for 2014 and 2015, while the TDX25 appears for 2015. Both models are tied to the electrical system and diesel engine.

What's the safety risk?
Long low-speed idling with heavy electrical demand can overheat the alternator and increase the risk of a fire. Until the repair is complete, avoid extended idling with heavy electrical loads and schedule service soon. Van Hool service technicians correct the engine idle speed setting and replace the alternators. Repair is free at any franchised Van Hool dealer.
What should I do?
- Check your VIN to confirm your 2014-2015 Van Hool TD925 or TDX25 is included in this recall.
- Contact your nearest franchised Van Hool dealer to schedule the free repair that corrects the Cummins engine idle speed setting and replaces the alternators tied to the overheating risk.
- Bring the recall notice if Van Hool or ABC Bus has mailed one. If not, reference recall number 15V422 and Van Hool recall P764 when you call.
- Avoid prolonged idling with high electrical demand until the idle-speed correction and alternator replacement are complete.
What happens at the repair
At service, Cummins technicians correct the engine idle speed setting so the affected buses are not set too low. Van Hool also says the alternators need to be replaced during the next scheduled maintenance. The recall work is free of charge, and parts and labor are covered. Van Hool has a general reimbursement plan on file for owners who already paid for related repairs before the recall work was handled. Bring repair invoices or other documentation to the service desk and ask how to submit them under that plan.
