| Check Engine (MIL) | AMBER | The engine management system on your JCB 215 has detected a fault related to emissions or performance. | Have the engine diagnostics checked by a JCB technician. | |
| Engine Oil Pressure | RED | Low oil pressure in the JCB 215's engine can cause severe damage if not addressed immediately. | Stop the engine and check oil level; if low, top up; if light persists, do not restart. | |
| Battery / Charging | RED | The alternator on the JCB 215 is not charging the battery properly. | Check alternator belt and connections; if light stays on, have charging system inspected. | |
| Coolant Temperature | RED | Engine coolant temperature on the JCB 215 is above safe operating limits. | Stop engine immediately and allow to cool; check coolant level and for leaks. | |
| Transmission Temp | AMBER | The transmission fluid temperature in your JCB 215 is high, which may reduce performance. | Reduce load and allow transmission to cool; check fluid level and cleanliness. | |
| Brake System | RED | A fault has been detected in the brake system of the JCB 215, potentially affecting stopping ability. | Stop the machine safely and inspect brake fluid level and lines. | |
| Parking Brake | RED | The parking brake on the JCB 215 is engaged or a fault in the brake system is present. | Release the parking brake before moving; if light remains, check brake system. | |
| Glow Plug / Preheat | AMBER | The glow plugs on your JCB 215 are active for cold start preheating. | Wait until the light goes out before starting the engine. | |
| Low Fuel | AMBER | The fuel level in the JCB 215 is low and needs refilling soon. | Refuel as soon as possible to avoid running out on site. | |
| Hydraulic System | RED | Hydraulic system pressure or temperature on the JCB 215 is outside normal range, risking component damage. | Stop the engine and check hydraulic oil level and for leaks. | |
| Water in Fuel | AMBER | Water has been detected in the fuel system of your JCB 215, which can damage injectors. | Drain water from the fuel filter separator immediately. | |
| Air Filter | AMBER | The engine air filter on the JCB 215 is restricted and needs servicing. | Check and replace the air filter element if dirty. | |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Faulty thermostat
- Blocked radiator
What to do
On the JCB 215, immediately stop the engine, allow it to cool, then check the coolant reservoir at the left side of the engine bay and verify radiator fins are clean.
Hydraulic System Failure
Common causes
- Low hydraulic oil
- Contaminated oil
- Failed hydraulic pump
What to do
Shut down the JCB 215 and check the hydraulic oil level dipstick near the rear axle; if low, add JCB HVLP oil; if contaminated, flush the system.
Transmission Overheating
Common causes
- Overloading
- Low transmission fluid
- Plugged cooler
What to do
Reduce bucket load and allow the JCB 215 to idle; check transmission fluid level at the right side of the engine; clean the cooler fins with compressed air.
Engine Oil Pressure Loss
Common causes
- Low oil level
- Oil pump failure
- Clogged oil filter
What to do
Stop the JCB 215 immediately; check engine oil level using the dipstick on the left side; if low, add 15W-40 oil; if still low, do not restart.
Brake System Malfunction
Common causes
- Brake fluid leak
- Worn brake pads
- Air in brake lines
What to do
Park the JCB 215 on level ground; check brake fluid reservoir under the cab floor; if low, inspect lines for leaks and bleed brakes if spongy.
Frequently Asked Questions
Why does my JCB 215 show a Master Warning light after starting?
It indicates a critical fault detected by the ECU; check the display for a code (e.g., S022) and contact your dealer for diagnosis.
Can I operate the JCB 215 with the Check Engine light on?
You can, but reduced power and increased emissions may occur; schedule a diagnostic scan as soon as possible.
What should I do if the Hydraulic System light comes on while digging?
Stop loading immediately, move to a safe area, and shut down the engine; check hydraulic oil level in the tank behind the cab.
How often should I drain the water separator on the JCB 215?
Drain daily or when the Water in Fuel light appears; turn the knob on the separator under the fuel tank until clear fuel flows.
Why does my JCB 215's transmission light come on when driving uphill?
Heavy load on steep grades can overheat the transmission; shift to a lower gear and reduce bucket load to cool it down.
Is it normal for the glow plug light to stay on longer in cold weather?
Yes, on the JCB 215, the preheat time extends automatically below 0°C; wait until the light goes out before starting.
