Is your machine stopping at the worst possible moment? 🚜 Accurate construction equipment diagnostics with Jaltest INFO Web allows you to quickly identify issues and reduce costly downtime. Whether it’s a Caterpillar excavator, a JCB loader, or a tractor, all off-highway machines face similar problems: warning lights, power loss, hydraulic failures, and more.
Good news: with the right tools like Jaltest INFO Web, you can diagnose faster and get your machines back in action. Here are the five most common construction equipment diagnostics problems and practical solutions.
1. Hydraulic Failures in Construction Equipment Diagnostics
Hydraulic circuits are the heart of off-highway machines. Unstable pressure or slow movement can paralyze the entire machine.
Common causes:
- Low fluid level or contaminated oil can cause failures. Additionally, clogged filters may also lead to issues.
- Clogged filters
- Leaks in hoses
- Failing pumps or valves
Solution with Jaltest:
- First, check oil levels and condition. Then, perform guided sensor and solenoid tests.
- Live reading of pressures
- Test actuators and solenoids
- Targeted component repair
👉 Time saved: Jaltest’s built-in OEM values allow instant comparison with expected pressures.
2. Emission System Faults in Heavy Machinery Diagnostics
SCR and DPF systems often cause unexpected stops: AdBlue warning, power loss, or smoke.
Common causes:
- Incomplete regeneration
- Faulty NOx or pressure sensors
- Impure AdBlue
- Stuck EGR valve
Solution with Jaltest:
- Guided forced regeneration solves some emission problems. If that doesn’t work, replace faulty components
- Sensor and valve checks
- Replace faulty components
👉 Tip: Jaltest guides regeneration without unnecessary DPF disassembly.
3. CAN Bus Communication Errors in Construction Equipment Diagnostics
When multiple systems fail simultaneously, the issue often lies in the electronic network.
Common causes:
- Damaged wiring harness
- Oxidized connectors
- Grounding faults
- Faulty ECU
Solution with Jaltest:
- Full module scan
- Network topology visualization
- Quick identification of inactive modules
👉 Advantage: Jaltest’s CAN map eliminates guesswork.
4. Transmission Failures in Heavy Machinery Diagnostics
Poor gear shifts or unstable traction can make machines unusable.
Common causes:
- Old or insufficient oil
- Internal clutch wear
- Faulty sensors or solenoids
- Improper calibration
Solution with Jaltest:
- Check oil levels and condition
- Guided sensor and solenoid tests
- Automatic calibration after repair
👉 Benefit: Simplified recalibration avoids full disassembly.ssembly.
5. Engine Power Loss
A smoky, high-consuming, or stalling engine can have multiple causes.
Common causes:
- Clogged injectors
- Leaking turbo
- Faulty pressure or temperature sensor
- Intake issues
Solution with Jaltest:
- Read engine fault codes
- Cylinder cut-out tests
- Pressure and air leak analysis
👉 Key to success: Real-time data helps distinguish mechanical issues from electronic faults.
