The ASV VT-100 is a compact track loader designed for tough jobs, with a simple instrument cluster to keep you informed. These warning lights help you monitor critical systems and avoid downtime.
ASV VT-100 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | This red light appears when a critical fault is detected, such as low oil pressure or overheating, and requires immediate engine stop on your VT-100. | Stop the engine safely and investigate the primary issue indicated by other lights. | |
| Master Caution | AMBER | This amber light illuminates to alert you of a non-critical condition, like a service reminder or low fluid level, specific to the VT-100's systems. | Check the secondary warning lights and address the condition before continuing operation. | |
| Check Engine (MIL) | AMBER | This indicator comes on when the engine management system detects a fault in the VT-100's emissions or fuel system, such as a sensor issue. | Have the engine diagnostic codes read by a qualified technician as soon as possible. | |
| Engine Oil Pressure | RED | This red light warns of low engine oil pressure, which can cause severe damage if ignored on your VT-100. | Immediately stop the engine, check oil level, and look for leaks. | |
| Battery / Charging | RED | This light indicates the alternator is not charging the battery properly, which could lead to electrical failure on your VT-100. | Check battery connections and alternator belt; if light stays on, service the charging system. | |
| Coolant Temperature | RED | This red alert shows the engine coolant is overheating, a common issue in heavy use of the VT-100's compact loader. | Stop the engine, let it cool, and check coolant level and radiator for blockages. | |
| Hydraulic System | AMBER | This amber light signals a hydraulic system concern, such as low oil level or filter restriction in your VT-100. | Check hydraulic oil level and condition; if light persists, consult manual for filter replacement. | |
| Glow Plug / Preheat | AMBER | This light stays on while the glow plugs are heating the engine for cold starts on your VT-100; it will turn off when ready. | Wait for the light to go out before cranking the engine in cold weather. | |
| Low Fuel | AMBER | This amber light alerts you that the fuel level is low, important to avoid running out during operation on your VT-100. | Refuel as soon as possible to prevent engine stalling. | |
| Seat Belt | RED | This safety light reminds you to fasten the seat belt before operating the VT-100; it may flash or stay on until belted. | Fasten your seat belt immediately to comply with safety rules. | |
| Parking Brake | RED | This red indicator shows the parking brake is engaged; some VT-100 models also warn if it is not fully released. | Release the parking brake before moving the machine. | |
| High Beam | BLUE | This blue light indicates the high beam headlights are on, improving visibility in dark work sites on your VT-100. | Dim the lights when approaching other operators or vehicles. | |
| Work Lights | GREEN | This green light confirms the auxiliary work lights are activated, providing extra illumination for the VT-100's attachment area. | Use work lights as needed; turn off when not required to save battery. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Clogged radiator fins
- Faulty thermostat
What to do
Stop the VT-100 immediately, allow the engine to cool, then check coolant and clean the radiator. If problem persists, inspect the thermostat and water pump.
Low Engine Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Worn bearings
What to do
Shut down the engine and check oil level, top off if low. If the light stays on, have the oil pump and pressure relief valve inspected by a technician.
Hydraulic System Fault
Common causes
- Low hydraulic fluid
- Clogged filter
- Leak in hoses or fittings
What to do
Check hydraulic oil level and look for leaks; replace the filter if service is due. Do not operate the VT-100 until the issue is resolved.
Battery Charging Failure
Common causes
- Loose or corroded battery cables
- Bad alternator
- Worn drive belt
What to do
Inspect battery connections and alternator belt; clean corrosion. If light remains, test the alternator output or replace it.
Engine Check Light On
Common causes
- Faulty sensor
- Emissions system issue
- Fuel quality problem
What to do
Continue operation if drivability is normal, but schedule diagnostic scanning. For the VT-100, check fuel filter and ensure proper fuel grade.
Frequently Asked Questions
Why is my VT-100's master warning light on but no other lights?
The master warning may illuminate due to an intermittent fault, like a brief electrical glitch. Check the VT-100's diagnostic menu (if equipped) or cycle the key; if it stays on, have the ECU scanned.
Can I run the VT-100 with the amber hydraulic light on?
It's not recommended. The amber light indicates low oil or a filter issue. Continued use may damage the hydraulic pump. Check fluid and filter first.
How do I reset the check engine light on my VT-100?
The check engine light will reset after the fault is repaired and a few key cycles. To clear it manually, a diagnostic tool is required; do not disconnect the battery as it may clear other settings.
Why does my glow plug light flash?
A flashing glow plug light on the VT-100 often indicates a fault in the preheat system, such as a bad glow plug or relay. Have the system tested before cold weather operation.
What does the low fuel light look like on the VT-100?
It's an amber fuel pump symbol. When it comes on, you have roughly 10-15% fuel remaining, depending on the model. Refuel promptly to avoid air in the system.
Is the seat belt light integrated with the parking brake?
On most VT-100 models, the seat belt light is independent, but some years may chime if the belt is not fastened with the parking brake released. Always fasten the belt before moving.
