Know which machine to open first
Health scores from fault codes, hours, inspections and fluids.
- Go-live
- Live in 10 working days
- How you buy it
- Module in the Shop plan
A fault code that clears itself on Tuesday is easy to ignore, until it returns three times by Friday. Asset health keeps the whole pattern: codes, hours since service, inspection defects and fluid results, scored per machine, with a draft work order behind every alert.
How health scores go live
- Days 1 to 3
Collect the history
Fault codes from gateways and maker feeds, past work orders, inspection defects and oil sample results come in.
- Days 4 to 6
Set the weights
Your shop lead decides which codes always matter, which can wait, and how much each input moves the score.
- Days 7 to 8
Route the alerts
Critical codes go to the mechanic on call. Slow trends go to the weekly shop review.
- Days 9 to 10
First ranked list
Every machine gets a score, and machines below your threshold open draft work orders for review.
What your shop lead receives
- Who it is for
- Shops with more machines than mechanics
- A health score from 0 to 100 for every machine, updated as data arrives
- Fault codes with SPN, FMI and occurrence count, plus a plain description where one is published
- A draft work order behind every alert, waiting for a person to approve
- Repeat-fault and trend flags for coolant, oil pressure and DPF regeneration
- Oil sample results charted per machine, imported from your lab’s report files
- A ranked list of machines for the weekly shop review
Is asset health the right fit?
Right for you if
- Fault codes reach an inbox and nobody reads them
- You send oil samples but the results sit in a folder
- Your mechanics need a ranked list, not 300 alerts a week
Look elsewhere if
- You want a guaranteed failure date for each component
- Most of your fleet predates electronic engines and reports no codes
Example: a pipeline contractor in Artesia
A midstream pipeline contractor based in Artesia runs 110 machines, from excavators and dozers to pipelayers and water trucks, along new gathering lines. Fault codes went to a shared inbox, about 300 a week, read when someone had time. After go-live, one excavator’s score drops from 82 to 61 in four days: a low coolant level code three times, a coolant top-up on two inspections and 480 hours since its last service. The draft work order lists all three. A mechanic finds a weeping water pump seal while the machine is still working.
Fault codes, scores and work orders
Reading the fault code. Under SAE J1939-73, a diagnostic trouble code combines a Suspect Parameter Number (SPN, 19 bits), a Failure Mode Identifier (FMI, 5 bits) and an Occurrence Count (7 bits). The SPN names the part or reading involved, the FMI describes how it failed, and the count shows how often. Gytix keeps all three, so a code that fired 40 times stands apart from one that fired once. Machines on a maker feed that uses its own codes keep them exactly as sent.
What goes into the score. Each machine’s score combines four inputs: fault history, hours since the last service, open inspection defects, and fluid trends from oil samples and logged top-ups. Your shop lead sets how much each input counts and which codes are always critical. The score ranks machines by how much evidence points to trouble. It does not predict the day a part will fail, and we do not claim it does.
Every alert has a next step. An alert with no action attached is noise. Each one in Gytix opens a draft work order holding the code and its history, the machine’s hours and location, and the last service. A person approves it, edits it or dismisses it with a reason, and that decision stays on the machine’s record for the next mechanic and for any warranty claim.
Alongside the schedule. Health scores do not replace preventive maintenance. The schedule keeps the 500-hour service on time; the score catches what happens between services, such as a seal that starts weeping at 380 hours. Both run on the same engine hours and the same work orders, so a mechanic who opens a scheduled service also sees any open health alerts on that machine.
Asset health questions, answered
What is predictive maintenance for heavy equipment?
It means servicing a machine based on what its data shows, not only on the calendar or the hour meter. Gytix combines fault codes, hours since service, inspection defects and fluid trends into a health score per machine, so your shop sees which machines need attention first.
Can Gytix predict when a machine will fail?
No, and we do not claim to. The health score ranks machines by how much evidence points to a problem: repeat fault codes, overdue service, open defects and worsening fluid results. It tells your shop where to look first. A mechanic still decides what is wrong and what to fix.
What happens when a fault code comes in?
It is logged with its SPN, FMI and occurrence count, added to the machine’s history and checked against the rules your shop set. Codes marked critical alert the mechanic on call right away. Every alert opens a draft work order with the code, hours and location for a person to approve.
Can we use our oil analysis results?
Yes. Oil sample results are imported per machine from your lab’s report files and charted over time, so a rising wear metal or fuel dilution reading shows as a trend instead of a line in a PDF. A worsening trend lowers the health score and can open a draft work order.
How is asset health monitoring priced?
It is part of the Shop plan, billed per machine per month, month to month, with unlimited users. The Shop plan also includes preventive maintenance, work orders, parts and inventory, and warranty tracking. Fault codes come from A1 gateways or the manufacturer feeds you already have. The written quote after a walkthrough on your own fleet gives the exact figure.
