| DPF / Regeneration | AMBER | The Diesel Particulate Filter in your T6.145 needs regeneration to clear soot buildup for emissions compliance. | Drive at higher engine load or perform a parked regen as per manual. | |
| DEF / AdBlue | AMBER | DEF fluid level is low in the T6.145's SCR system; engine power may be reduced if ignored. | Refill DEF tank with clean fluid to restore performance. | |
| Water in Fuel | AMBER | Water has been detected in the fuel filter/separator of your T6.145; it can damage the injection system. | Drain the water from the fuel filter bowl according to the manual. | |
| Low Fuel | AMBER | Fuel level in the T6.145 is below 1/4 tank; avoid running out to prevent fuel system air ingress. | Refuel as soon as possible. | |
| High Beam | BLUE | The high-beam headlights on the T6.145 are activated for improved nighttime visibility. | Dim when approaching other vehicles to avoid blinding them. | |
| Hydraulic System | RED | The hydraulic system in your T6.145 has low pressure or a fault; implement operation may be affected. | Stop implements and check hydraulic fluid level and pump. | |
| PTO Engaged | AMBER | The Power Take-Off shaft on the T6.145 is engaged and rotating; keep clear of moving parts. | Disengage PTO before servicing implements. | |
| Differential Lock | AMBER | The differential lock on the T6.145 is engaged for increased traction in slippery conditions. | Disengage when turning or on hard surfaces. | |
| Work Lights | GREEN | The auxiliary work lights on the T6.145 are illuminated for improved field visibility at night. | Turn off when on public roads to avoid glare. | |
| Beacon / Rotating Light | GREEN | The rotating amber beacon on the T6.145 is active, warning others of a wide or slow-moving vehicle. | Ensure beacon is operational when on roads. | |
| Air Filter | AMBER | The engine air filter on the T6.145 is clogged; reduced airflow can decrease power and fuel economy. | Replace the air filter element according to the service interval. | |
| Fuel Filter / Water Separator | AMBER | The fuel filter is restricted or needs replacement on your T6.145; water may be present. | Replace the fuel filter and drain any water from the separator. | |
| Service / Hour Meter | AMBER | The T6.145 has reached a scheduled service interval based on engine hours; maintenance is due. | Perform the required service as outlined in the maintenance schedule. | |
| Reduced Power (Limp Mode) | AMBER | The T6.145's ECU has limited engine power to protect the drivetrain due to a fault. | Reduce load and drive to a safe location; have the vehicle diagnosed. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Clogged radiator fins
- Faulty thermostat
What to do
For the T6.145, stop the engine and allow it to cool. Check coolant reservoir, clean radiator fins with compressed air, and inspect the fan belt tension. If overheating persists, consult your New Holland dealer.
Transmission Overheating
Common causes
- Continuous heavy load at low speed
- Low transmission oil level
- Clogged oil cooler
What to do
Reduce load and shift to a higher gear. On the T6.145, use the transmission oil temperature gauge to monitor. Check oil level and replace the cooler filter if applicable. Let the transmission cool in neutral before resuming work.
Brake Failure
Common causes
- Low brake fluid
- Worn brake pads/discs
- Air in the hydraulic lines
What to do
Do not operate the tractor. For the T6.145, check the brake fluid reservoir and top up with DOT 4 fluid. Inspect lines for leaks. Bleed the brakes if spongy. Have brakes inspected by a certified New Holland technician.
DPF Regeneration Required but Ignored
Common causes
- Frequent short-duration operation
- Low exhaust temperature
- Faulty sensors
What to do
On the T6.145, drive with higher engine load (above 1500 rpm) for 20-30 minutes to initiate passive regeneration. If the light remains, perform a stationary regeneration via the information display. If it fails, sensor cleaning or replacement may be needed.
Hydraulic System Leak
Common causes
- Damaged hose
- Loose fitting
- Seal failure in cylinder
What to do
Stop the engine and lower all implements. Identify the leak source on the T6.145's hydraulic system. Tighten fittings, replace damaged hoses, and top up with NH hydraulic fluid. If internal seal failure, contact your dealer.
Frequently Asked Questions
Why is the Master Warning light on and my T6.145 engine shut off?
This indicates a serious fault, often low oil pressure or high coolant temperature. Check the information display for the specific code. Do not restart until the root cause is resolved. Contact your New Holland dealer for diagnostics.
How often should I check the DEF level on the T6.145?
Check the DEF gauge during daily pre-trip inspections. The T6.145 holds 6.2 gallons of DEF; expect consumption of about 2-3% of diesel fuel used. Refill when the light comes on to avoid power derate.
Can I drive with the DPF regeneration light on?
Yes, you should drive the T6.145 at moderate to high engine load for 30-40 minutes to complete regeneration. Avoid prolonged idling. If the light flashes, try a parked regen via the information menu.
What does the amber glow plug light mean during summer?
Even in warm weather, the T6.145 might preheat for a few seconds if the engine is cold. Wait until it goes out before starting. If it stays on longer than 10 seconds, have the glow plug system checked.
How do I reset the service hour meter on the T6.145?
The service light resets automatically after the dealer performs the service. To reset manually, navigate to the service menu in the display, select 'Reset Service', and confirm. Refer to the operator's manual for exact steps.
Why is my battery light on but the battery seems charged?
The battery light indicates a charging system issue. On the T6.145, check the alternator belt for looseness or damage. Also inspect the wiring harness at the alternator. A faulty voltage regulator is common and requires replacement.
