The Case CE CX370D excavator features a comprehensive instrument cluster with warning and indicator lights to monitor engine, hydraulics, and safety systems. Understanding these lights is crucial for safe operation and preventing costly downtime on your CX370D.
Case CE CX370D Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | This red light on the CX370D signals a severe fault that demands an immediate engine stop to prevent damage. | Safely shut down the engine and investigate the associated fault code on the display. | |
| Master Caution | AMBER | Amber caution on the CX370D alerts you to a non-critical issue that still requires prompt diagnosis. | Check the monitor for a detailed warning message and schedule service soon. | |
| Check Engine | AMBER | This amber light illuminates on the CX370D when the engine control unit detects a fault in emissions or performance. | Have the engine diagnostic codes read by a Case dealer to identify the issue. | |
| Engine Oil Pressure | RED | Red oil light on the CX370D indicates dangerously low oil pressure, risking engine seizure. | Stop the engine immediately and check oil level and pressure sensor. | |
| Battery / Charging | RED | Red battery light on the CX370D means the alternator is not charging or the battery voltage is low. | Check alternator belt and battery connections; if light persists, contact service. | |
| Coolant Temperature | RED | This red light warns that the CX370D's engine coolant temperature is excessively high, risking overheating. | Shut down the engine, let it cool, and inspect coolant level and radiator for blockages. | |
| Hydraulic System | AMBER | Amber hydraulic light on the CX370D indicates a fault in the hydraulic circuit, such as low oil level or filter blockage. | Check the hydraulic oil level and filters; if light stays on, consult a technician. | |
| Swing / Slew Lock | AMBER | Amber swing lock light on the CX370D confirms the upperstructure slew lock is engaged for transport or maintenance. | Release the lock before operating the excavator if safe to do so. | |
| Work Lights | BLUE | Blue work light indicator shows the auxiliary lighting on the CX370D is turned on for low-visibility conditions. | No action needed; turn off when not required to conserve battery. | |
| Beacon / Rotating Light | AMBER | Amber beacon light confirms the rotating warning light on the CX370D is active for safety on job sites. | Ensure beacon is off when not operating to avoid distraction. | |
| Low Fuel | AMBER | Amber low-fuel light on the CX370D warns the diesel level is low and refueling is needed soon. | Add diesel fuel to avoid air entering the system and causing starting issues. | |
| Glow Plug / Preheat | AMBER | Amber glow plug indicator on the CX370D illuminates during cold start preheating and extinguishes when ready. | Wait until the light turns off before cranking the engine. | |
| Seat Belt | AMBER | Amber seat belt reminder on the CX370D tells you the seat belt is not fastened; audible chime may also sound. | Fasten your seat belt before operating the machine. | |
| Door Open | AMBER | Amber door icon indicates the cab door of the CX370D is open or not fully latched. | Close and secure the door before moving the excavator. | |
| High Exhaust Temp (HEST) | AMBER | Amber HEST light on the CX370D signals the exhaust aftertreatment system temperature is very high, often during regeneration. | Keep the machine away from flammable materials; allow regeneration to complete. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Clogged radiator or air intake
- Faulty thermostat or water pump
What to do
For the CX370D, first check coolant level and radiator cleanliness. If low, refill with approved coolant; if frequent, inspect for leaks or debris blocking the cooling pack.
Low Engine Oil Pressure
Common causes
- Low oil level
- Worn oil pump
- Clogged oil filter or passages
What to do
Stop the CX370D immediately, check dipstick, and top off oil if low. If pressure doesn't return, have a Case technician inspect the oil pump and relief valve.
Hydraulic System Failure
Common causes
- Low hydraulic oil level
- Contaminated oil or filter
- Faulty pump or relief valve
What to do
On the CX370D, check hydraulic oil level and condition (cloudy/foamy indicates contamination). Replace filters and bleed air; if symptoms persist, test pump pressure.
Electrical / Charging Problem
Common causes
- Loose or corroded battery cables
- Alternator belt slip
- Faulty alternator or battery
What to do
Inspect cables and belt tension on the CX370D. If belt is fine, measure battery voltage; below 12.4V suggests charging issue. Have alternator output tested.
Fuel System Issue
Common causes
- Low fuel or water in fuel
- Clogged fuel filter
- Air in fuel lines
What to do
For the CX370D, drain water separator, replace fuel filter if not changed recently, and prime the system using the hand pump if air is suspected.
Frequently Asked Questions
Why does my CX370D's master warning light come on but no other lights?
This usually indicates a logged fault code in the engine or machine ECU. Use the monitor to scroll through active codes and consult your Case dealer for diagnostics.
How do I reset the service hour meter on the CX370D?
The service interval reminder on the CX370D can only be reset by a Case dealer using service software; it's not a user-accessible reset. Keep records of actual maintenance.
What does the amber swing lock light mean if it stays on while excavating?
If the swing lock light remains on during normal operation, the slew lock solenoid or switch may be stuck or there's a hydraulic interlock fault. Safely shut down and check the lock mechanism.
Is it safe to operate the CX370D with the high exhaust temp light on?
The light indicates the aftertreatment system is in regeneration. It's safe but keep the machine away from combustibles. Do not shut down until regeneration completes if possible.
Why does my CX370D glow plug light flash?
A flashing glow plug light on the CX370D typically indicates a fault in the preheat system, such as a failed glow plug or relay. Have it checked before cold starts become difficult.
Can I ignore the low fuel light on my CX370D?
Running the CX370D low on diesel can introduce air into the fuel system, causing hard starting and potential injector damage. Refuel as soon as the light illuminates.
