Frequently Asked Questions
What should I do if the Check Engine light comes on while driving my Iveco T-Way?
If the light is steady, you can continue driving but should schedule a diagnostic soon. If it flashes, reduce power and stop to avoid catalytic converter damage; have the fault codes read by an Iveco technician.
How do I perform a DPF regeneration on the Iveco T-Way?
The vehicle will automatically initiate regeneration when driving at speeds above 30 mph (50 km/h) for about 20-30 minutes. If the DPF light is on, drive at highway speeds; if it blinks, take it to a dealer for a stationary regeneration.
Why does the ABS light stay on after starting?
A persistent ABS light indicates a fault in the wheel speed sensors or modulator. The standard brakes still work, but you should have the system diagnosed to restore anti-lock function, especially in off-road conditions.
What does the amber master caution light mean?
It means there is a non-critical warning in one of the vehicle systems. Check the information display for a specific message, such as low tire pressure or a service reminder. You can continue driving but should address the issue soon.
How often should I drain the water separator on the T-Way?
Drain the water-in-fuel separator daily if you operate in humid conditions, or at each fuel fill. If the water-in-fuel light comes on, drain immediately to protect the high-pressure injection system.
Is it safe to continue with the AdBlue warning light on?
If it's amber, you have a few hundred miles of range, but the engine power will be reduced if the tank runs dry. Refill as soon as possible. If it's red, the SCR system has a fault; you may need to stop and call for service to avoid a derate.
