JalTool Drilling Rig Diagnostic Tool for Engine, Hydraulic and Drilling Control Faults
Modern drilling rigs use electronic systems to control diesel engines, hydraulic pumps, rotary heads, feed systems, crawler travel, winches, control panels and emissions equipment. When a drilling rig loses torque, moves slowly or displays multiple warning codes, the problem may be electronic, hydraulic, mechanical or related to CAN communication.
The JalTool Drilling Rig Diagnostic Tool helps professional workshops, drilling contractors and mobile technicians inspect supported drilling equipment through a structured scan, test and verification process.
Common Drilling Rig Fault Symptoms
Drilling performance depends on several systems working together. A loss of drilling force may be caused by hydraulic pressure, engine derate, a sensor signal, a control valve, an electronic controller or a mechanical component.
- Rotary head loses speed or torque
- Feed and pullback movement becomes slow
- Hydraulic pressure is unstable
- Winch or auxiliary functions stop responding
- Crawler travel or steering operates incorrectly
- Engine power is reduced under load
- Operator display shows controller communication faults
- DPF, SCR, AdBlue or NOx warning codes appear
A professional diagnostic scanner can help identify whether the first fault is located in the engine ECU, hydraulic controller, drilling control module, sensor circuit, wiring harness or communication network.
What Can JalTool Check on a Supported Drilling Rig?
Available functions depend on the manufacturer, model, production year, engine, ECU and installed system. On supported drilling rigs, JalTool may provide access to the following diagnostic areas:
| System | Possible Diagnostic Functions |
|---|---|
| Engine ECU | Read supported fault codes, view live data and identify engine control information |
| Hydraulic control | Inspect supported pressure signals, temperature values, sensors and control commands |
| Rotary head and feed system | Review supported controllers, actuator signals and electronic faults |
| Winch and auxiliary functions | Check supported motors, valves, switches and controller data |
| Travel and steering | Inspect supported travel controllers and CAN communication faults |
| Aftertreatment system | Diagnose supported DPF, SCR, AdBlue and NOx-related systems |
| Service functions | Perform supported resets, calibrations, adaptations and adjustments |
Not every function is available for every drilling rig. Confirm the exact machine details through the JalTool Vehicle Coverage page before purchasing.
Recommended JalTool Drilling Rig Diagnostic Workflow
1. Record the Machine Information
Prepare the manufacturer, exact model, serial number, production year, engine model and diagnostic connector information. Record whether the symptom occurs during rotary drilling, feed movement, winch operation, travel or high-load operation.
2. Inspect Power and Wiring
Check battery voltage, fuses, grounds, connectors and visible harness damage. Dust, water, vibration and oil contamination can cause poor connections or communication problems between electronic control units.
3. Perform a Full Supported System Scan
Connect the JalTool Diagnostic Scanner and scan all available electronic systems. Save active and stored fault codes before clearing them. Compare engine, hydraulic, drilling-control and travel-system codes to identify related faults.
4. Review Live Data
Use supported live data to compare engine speed, hydraulic pressure signals, oil temperature, joystick input, rotary-head commands, feed-position sensors, valve current and controller voltage. Values that do not match the actual machine condition require further testing.
5. Perform Supported Actuator Tests
Where available, actuator tests can help verify valves, solenoids, relays, motors and other electronically controlled components. Secure the drilling rig before testing and follow the manufacturer’s safety instructions. Keep personnel away from the rotary head, drill string, winch, tracks and moving hydraulic components.
6. Repair, Calibrate and Verify
After repairing wiring, replacing a sensor or correcting a hydraulic problem, complete any supported calibration or adjustment. Clear codes only after the repair, then perform another scan and save a diagnostic report for the service record.
Choosing a JalTool Package for Drilling Equipment
Workshops that service drilling rigs together with construction machinery, agricultural equipment and commercial vehicles can review the JalTool Professional Package.
Businesses that work with several equipment categories can review the JalTool Complete Diagnostic Package for broader supported coverage.
Workshops focused mainly on trucks and commercial vehicles can consider the Commercial Vehicle Package. The diagnostic interface and connection hardware are available through the JalTool Diagnostic Scanner hardware page.
Confirm Compatibility Before Ordering
A manufacturer name alone does not confirm support for every drilling rig, engine, hydraulic controller or drilling system. Send the exact model, year, engine, ECU and required function, such as live-data testing, actuator testing, calibration or emissions diagnosis.
For compatibility and package assistance, contact support@jaltool.com or WhatsApp at +84 908 532 146.
Purchase from an Authorized JalTool Source
Before paying for hardware or software activation, verify the seller through the JalTool Authorized Dealer Verification page. Businesses interested in distribution can visit the JalTool Dealer Program.
Important Compatibility Notice
JalTool is an independent diagnostic product and is not affiliated with, sponsored by or endorsed by Cojali or Jaltest. Diagnostic coverage and available functions depend on the manufacturer, model, production year, engine, ECU, installed system and supported procedure. Always confirm compatibility and follow the drilling rig manufacturer’s safety instructions before testing.
