How to clear error codes on a New Holland T4 series tractor?
For an "SCR Catalyst Full" fault, manually increase the engine speed to 1500 RPM until the warning light turns off. For DEF/AdBlue® level faults, refill the tank and then cycle the key switch OFF then ON to reset the system. For most other fault codes, the manual advises contacting an authorized dealer for resolution.
What do New Holland T4 dashboard warning lights mean?
The dashboard warning lights provide information on system operation or malfunctions. For example, an amber differential lock warning light (2) indicates the differential lock is engaged, while a green four-wheel drive warning light (3) illuminates when drive to the front wheels is engaged. A red "Stop" warning light (12) indicates a critical fault, requiring immediate tractor shutdown and investigation.
How to perform a forced regen or troubleshoot DPF-related faults on a T4 tractor?
If the "SCR Catalyst Full" message appears, indicating hydrocarbon accumulation, place the machine in park, apply the hand brake, and manually increase the engine speed to 1500 RPM. Allow the machine to run at this speed until the warning light turns off, which may take approximately 1-2 hours depending on ambient temperature.
