Steyr 6150 CVT Warning Light Symbols

SymbolNameColorWhat it meansWhat to do
Master Warning (Stop)REDA critical fault is detected in the Steyr 6150 CVT, such as engine overspeed or low oil pressure, requiring an immediate engine stop.Stop the tractor safely, engage the parking brake, and shut off the engine. Consult the display for the specific fault code.
Master CautionAMBERA non-critical system issue has been logged by the Steyr 6150 CVT's electronic control unit, such as a sensor fault or fluid level drop.Check the multifunction display for the specific warning message and address it during your next stop or scheduled service.
Check Engine (MIL)AMBERThe engine management system has detected a malfunction in the Steyr 6150 CVT's Tier 4 Final engine, such as a DPF issue or oxygen sensor fault.Reduce engine load and continue to a safe location. Have the engine diagnosed by a certified Steyr technician.
Engine Oil PressureREDEngine oil pressure has dropped below safe levels in the Steyr 6150 CVT's 6-cylinder, potentially due to low oil level or a failing pump.Immediately stop the engine. Check oil level and inspect for leaks; do not restart until the issue is resolved.
Battery / ChargingREDThe alternator is not charging the battery properly, which could drain the Steyr 6150 CVT's electrical system during operation.Check alternator belt tension and connections. If persistent, have the charging system tested.
Coolant TemperatureREDEngine coolant temperature has exceeded the safe operating range, possibly due to low coolant or a blocked radiator in the Steyr 6150 CVT.Stop the engine and let it cool. Check coolant level and radiator fins for debris. Do not open the hot coolant cap.
ATTransmission TempAMBERThe CVT transmission fluid temperature is high, often caused by heavy load or low fluid level in the Steyr 6150 CVT.Reduce load or shift to a lower gear to allow the transmission to cool. Check fluid level when safe.
Brake SystemREDA fault in the hydraulic brake circuit or low brake fluid has been detected, reducing braking effectiveness on the Steyr 6150 CVT.Stop immediately and avoid moving the tractor. Check brake fluid reservoir and lines for leaks.
PParking BrakeAMBERThe parking brake is engaged on the Steyr 6150 CVT; this light typically extinguishes when the brake is released.Release the parking brake before moving. If the brake does not disengage, seek service.
Glow Plug / PreheatAMBERThe glow plugs are heating the intake air for cold starting; wait until the indicator turns off before cranking the Steyr 6150 CVT engine.Turn the key to the preheat position and wait for the light to go out before starting.
DPF / RegenerationAMBERThe diesel particulate filter is undergoing active regeneration to burn off soot; the Steyr 6150 CVT may run at higher idle to complete the process.Continue normal operation if possible; avoid stopping the engine during regeneration to prevent incomplete cleaning.
DEF / AdBlueAMBERThe Diesel Exhaust Fluid level is low or a quality issue is detected, which can affect emissions compliance on the Steyr 6150 CVT.Refill DEF at the earliest opportunity. If the light flashes, consult the dealer for a sensor issue.
Water in FuelAMBERWater has been detected in the fuel filter/water separator, which can cause injector damage on the Steyr 6150 CVT's common-rail system.Drain the fuel filter/water separator immediately. If the light persists, replace the filter element.
Low FuelAMBERThe fuel level is low; the Steyr 6150 CVT's engine may draw air if driven dry, leading to priming issues.Refill diesel fuel as soon as possible. Avoid running the tank completely empty.
Hydraulic SystemAMBERA hydraulic system fault has been detected, such as low oil level or a filter restriction, affecting implements on the Steyr 6150 CVT.Check hydraulic oil level and condition. Reduce implement use until the fault is resolved.
Fuel Filter / Water SeparatorAMBERThe fuel filter is clogged or requires maintenance, which can reduce engine power and fuel efficiency on the Steyr 6150 CVT.Replace the fuel filter element as per the maintenance schedule. If light remains, check for air in the fuel system.
Service / Hour MeterAMBERThe scheduled service interval is approaching or due for the Steyr 6150 CVT, based on engine hours.Schedule routine maintenance including oil, filters, and fluid checks as outlined in the operator's manual.
Work LightsBLUEThe rear or front work lights are illuminated for enhanced visibility during night operations on the Steyr 6150 CVT.No action required unless the lights are left on unintentionally.
Beacon / Rotating LightGREENThe rotating beacon is activated, indicating the Steyr 6150 CVT is in operation and drawing attention for safety.Ensure the beacon is used whenever the tractor is moving on public roads or in low-visibility conditions.
Differential LockAMBERThe differential lock is engaged, providing improved traction on soft ground but limiting steering on the Steyr 6150 CVT.Disengage the differential lock after overcoming the obstacle to avoid transmission wind-up.
PTOPTO EngagedGREENThe power take-off is engaged and rotating at the selected speed, ready to drive implements on the Steyr 6150 CVT.Verify that the PTO shaft and implement are properly connected before operation. Disengage when not in use.
EBEngine / Exhaust BrakeAMBERThe exhaust brake is active to assist with speed control on descents, reducing wear on the service brakes of the Steyr 6150 CVT.Use the exhaust brake on slopes to maintain a safe speed. This light confirms the system is on.

Most Important Warning Lights

Engine Overheating

Common causes

  • Low coolant level
  • Faulty thermostat
  • Clogged radiator core

What to do

Stop the Steyr 6150 CVT immediately and allow the engine to cool. Check coolant level and top up with the specified mixture. If the issue recurs, inspect the radiator and cooling fan for obstructions.

Transmission Over-Temperature

Common causes

  • Prolonged heavy load in high ambient temperature
  • Low CVT fluid level
  • Blocked transmission oil cooler

What to do

Reduce load and shift to a lower gear. Verify CVT fluid level and top up if necessary. Clean the external transmission cooler fins with compressed air.

What to do

Perform a stationary regeneration by engaging the manual regen mode (consult manual). Take the Steyr 6150 CVT on a longer road run to allow passive regeneration. If the warning persists, have the DPF serviced by a dealer.

Hydraulic System Failure

Common causes

  • Low hydraulic oil level
  • Contaminated or degraded oil
  • Leak in a hose or fitting

What to do

Stop implement use and check oil level at the sight glass. Add the recommended oil type (e.g., Steyr HD 10W). Inspect under the tractor for leaks and tighten or replace faulty hoses.

Electrical System Fault

Common causes

  • Loose or corroded battery terminals
  • Failed alternator
  • Blown fuse or relay

What to do

Check battery connections and clean corrosion. Measure battery voltage with the engine running; if below 13.5V, the alternator may be failing. Replace blown fuses as indicated by the display.

Frequently Asked Questions

Why does my Steyr 6150 CVT show a red master warning when I start it in cold weather?

If the engine oil is too thick or battery voltage is low, the master warning may appear. Ensure battery is fully charged and use engine block heater if below -10°C. The light should go out after a few seconds if no actual fault exists.

How do I reset the service light on the Steyr 6150 CVT?

The service light is reset automatically after the scheduled maintenance is performed and the interval is reset via the diagnostic menu. Access through the right-hand control panel: press and hold the 'Menu' button until 'Service Reset' appears.

What does the blue work light indicator mean if it's flashing?

A flashing blue work light indicator indicates a fault in the lighting circuit, such as a burned-out bulb or a loose connection. Check the rear and front work light bulbs and replace any that are failed.

Can I continue operating my Steyr 6150 CVT with the amber transmission temp light on?

It is not recommended. Reduce load immediately. If the light goes out after a few minutes, you may continue at reduced power. If it stays on, stop the tractor and allow the CVT to cool. Extended operation may cause transmission damage.

Why does the DPF regeneration light come on during light field work?

Light load operations don't generate enough exhaust heat for passive regeneration. The ECU initiates active regeneration to burn accumulated soot. If possible, increase engine load (e.g., raise the implement) to assist the process.

How do I check the transmission oil level on the Steyr 6150 CVT?

Park on level ground with the engine off. Locate the dipstick on the left side of the transmission housing. Remove, wipe, reinsert fully, then check the level. Top up only with Steyr CVT fluid through the filler port.
