IVECO Daily 2018 Flashing Mileage
Ever had an IVECO Daily come in with flashing mileage on the dash and weren’t sure where to start?
This is one of the most common causes I’ve found.
First checks:
- Loose connections behind dash or under bonnet
- Fuses, relays & connectors
- Battery voltage and voltage drop
Bear in mind these use a smart charge system, so charging voltage may not increase at idle until the vehicle is driven. I always recommend checking charge rate during a road test.
While inspecting wiring, I found corrosion inside the TCM (Trailer Control Module) connector.
Plugged into JALTEST diagnostics for further investigation, which confirmed the TCM fault.
Replaced and reprogrammed the TCM — fault rectified and another happy customer 😀
Worth noting: Not all diagnostic tools can perform the programming procedure, so dealer-level programming may sometimes be required.
Anyone else had flashing mileage caused by something completely different?
