| Check Engine (MIL) | AMBER | The engine control unit has logged a fault in the Yanmar diesel engine of your ASV RT-50; performance may be affected. | Have the engine diagnostic codes read by a certified technician. | |
| Engine Oil Pressure | RED | Oil pressure is critically low in the RT-50's engine, risking severe internal damage if operation continues. | Stop the engine immediately and check oil level and pressure. | |
| Battery / Charging | RED | The charging system on the ASV RT-50 is failing; the battery is not being charged properly. | Check alternator belt and connections; recharge or replace battery. | |
| Coolant Temperature | RED | Engine coolant temperature is above safe limits on your RT-50, which can cause overheating and damage. | Stop engine, allow to cool, check coolant level and radiator. | |
| Transmission Temp | AMBER | Hydrostatic transmission fluid temperature is high in the ASV RT-50; reduce load to avoid overheating. | Reduce ground speed and load; if light persists, inspect cooling system. | |
| Parking Brake | AMBER | The parking brake on the RT-50 is engaged or not fully released; it may affect movement. | Release the parking brake before operating. | |
| Seat Belt | RED | The operator's seat belt is unbuckled on the ASV RT-50; the machine may be immobilized for safety. | Fasten the seat belt to proceed. | |
| Glow Plug / Preheat | AMBER | The glow plugs are active to aid cold starting of the RT-50's Yanmar engine; wait for light to extinguish. | Wait until the light goes out before cranking the engine. | |
| Low Fuel | AMBER | The fuel level in the ASV RT-50's tank is low; you have limited operating range left. | Refuel as soon as possible to avoid running out. | |
| Hydraulic System | RED | A fault exists in the hydraulic system of the RT-50; operation may be impaired or unsafe. | Stop the machine and inspect hydraulic fluid level and filters. | |
| Hydraulic Oil | AMBER | Hydraulic oil temperature or level is abnormal on the ASV RT-50; monitor for further warnings. | Allow system to cool or top off fluid as needed. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due on the ASV RT-50 based on engine hours; service is recommended. | Perform the required service per the maintenance schedule. | |
| Work Lights | GREEN | The work lights on the RT-50 are switched on, providing illumination for the work area. | Turn off when not needed to conserve battery. | |
| Beacon / Rotating Light | BLUE | The rotating beacon on the ASV RT-50 is active, indicating the machine is in operation for safety. | Ensure beacon is off when not operating. | |
| Cold Coolant | BLUE | Engine coolant temperature is below normal operating range on the RT-50; allow warm-up before heavy use. | Run the engine at low idle until the light turns off. |

Most Important Warning Lights
Engine Overheat
Common causes
- Coolant leak
- Clogged radiator
- Failed cooling fan
What to do
For the ASV RT-50, stop the engine, let cool, then inspect coolant level and radiator fins. Clean debris from the radiator and check hoses for leaks.
Hydraulic System Failure
Common causes
- Low hydraulic fluid
- Contaminated fluid
- Hydraulic pump failure
What to do
On the RT-50, check the hydraulic fluid level at the tank, inspect filters for blockage, and listen for pump noise. Top off fluid or replace filters; if pump is faulty, contact service.
Low Engine Oil Pressure
Common causes
- Low oil level
- Oil pump malfunction
- Worn bearings
What to do
Immediately shut down the ASV RT-50. Check oil level with the dipstick and add oil if low. If level is fine, internal damage may have occurred; have the engine inspected.
Battery Not Charging
Common causes
- Loose alternator belt
- Failed alternator
- Corroded battery terminals
What to do
Check the alternator belt tension on the RT-50, tighten if loose. Clean battery terminals and check connections. If light persists, test alternator output and replace if needed.
Transmission Overheat
Common causes
- Excessive load
- Low transmission fluid
- Clogged cooler
What to do
Reduce load and speed on the RT-50 immediately. Let the transmission cool, then check fluid level and ensure the cooler fins are clean. Avoid repeated heavy use until resolved.
Frequently Asked Questions
What does the Master Warning light on my ASV RT-50 mean?
The Master Warning (red stop light) indicates a critical fault that requires immediate engine shutdown to prevent damage. Check the display for additional messages and contact your dealer.
Why is my Check Engine light on in the RT-50?
The Check Engine light signals a fault in the engine's electronic control. On the ASV RT-50, common causes include sensor issues or fuel system problems. Have diagnostic codes read by a technician.
How do I reset the hour meter service light on the RT-50?
The service light resets only after the required maintenance is performed. For the ASV RT-50, follow the procedure in the operator's manual or use the service reset button if equipped.
My hydraulic system warning light is on; what should I do?
Stop the RT-50 immediately. Check the hydraulic fluid level and look for leaks. If fluid is low, top off with recommended oil. If the light stays on, inspect filters and hoses for damage.
Can I operate the ASV RT-50 with the transmission temperature light on?
No, operating with this light on can cause transmission damage. Reduce load and speed to let the system cool. If the light stays on, stop and check the cooling components.
Why does the glow plug light stay on for a long time in cold weather?
The glow plugs preheat the Yanmar engine of the RT-50. In very cold temperatures, the preheat cycle may take longer. Wait until the light turns off before cranking to ensure proper starting.
