Ranger 500 / Crew 500 fault codes (2026–2027)
The 2026 and 2027 Ranger 500 and Ranger 500 Crew manuals publish the same 51-entry diagnostic table. This page lists it once, with the manual citation for each model year and the compact utility-platform circuits behind the codes.
Scope note
This page covers the shared 51-entry table (OEM chapter 0001025947), published in the 2026 Ranger 500 / Crew 500 (P/N 9942300) and 2027 Ranger 500 / Crew 500 (P/N 9942392) owner’s manuals.
Each cited chapter has 52 raw table rows; repeated code rows are collapsed to 51 unique entries.
The 2022 600 AXYS snowmobile also has 51 codes, but it is a different table. It is not part of this group.
Table profile
This page reproduces 51 entries from 2 model-year records (2026–2027), 2 manual P/Ns, and chapter 0001025947.
Rows keep the manual’s printed order, from SPN 520208 / FMI 3 to SPN 84 / FMI 8.
Every row carries an SPN/FMI pair; 20 distinct SPNs and 9 FMI values appear.
The largest FMI groups are FMI 3 (17 rows), FMI 4 (15 rows), and FMI 5 (7 rows); together they account for 76% of the table.
The most repeated SPN is 110 (Engine Temperature Sensor) with 4 rows, followed by SPN 634 with 4 rows.
Every printed SPN/FMI pair carries one title in this table.
These counts describe the rows on this page, not every manual in the archive. The source box below lists the exact citation for every record on the page.
One table, two Ranger 500 years
The 2026 and 2027 Ranger 500 / Crew 500 manuals use diagnostic chapter 0001025947. The chapter has 52 raw rows; repeated code rows collapse to 51 unique entries. This page publishes the table once and keeps an anchor for each model year.
The old model-year URLs redirect to those anchors. The table rows are the same; the P/N and model-year citation are not.
What the 51 entries cover
The table covers throttle position and throttle safety, engine temperature, idle air control and idle speed, crankshaft position, system voltage and charging, fuel pump, fan, and several driver circuits. It is a compact table for a compact utility platform.
Many failure labels use the “Driver Circuit” wording — short to B+, grounded, or open/grounded. Those labels describe circuit faults; they do not identify a failed part.
How to use this page
Record the exact SPN and FMI, choose the anchor for your model year, and use the full table or the decoder. Note the manual P/N so the citation matches your machine. This page is a label index; it does not provide repair or safety procedures.
Which manuals use this table
The table is shared; the manual citation is not. Use the P/N for your exact model year.
| Year | Model | Manual P/N | Source |
|---|---|---|---|
| 2026 | Ranger 500 / Crew 500 | 9942300 | Open chapter |
| 2027 | Ranger 500 / Crew 500 | 9942392 | Open chapter |
Model and year notes
These notes explain which systems matter on each machine. They do not add rows to the OEM table.
Ranger 500 / Crew 500 (2026–2027)
Both model years publish this 51-entry table. The 2026 and 2027 manuals carry different P/Ns and running changes, but the diagnostic chapter is shared. Use the anchor for your year.

What the FMI number means
Every entry pairs an SPN with an FMI. The FMI is the failure type; the SPN is the circuit or component.
| FMI | What it generally means |
|---|---|
| 0 | Data valid, but above the normal operating range (most severe) |
| 1 | Data valid, but below the normal operating range (most severe) |
| 2 | Data erratic, intermittent, or incorrect |
| 3 | Voltage above normal, or shorted to a high source |
| 4 | Voltage below normal, or shorted to a low source |
| 5 | Current below normal, or open circuit |
| 6 | Current above normal, or grounded circuit |
| 7 | Mechanical system not responding or out of adjustment |
| 8 | Abnormal frequency, pulse width, or period |
| 9 | Abnormal update rate |
| 10 | Abnormal rate of change |
| 11 | Root cause not known |
| 12 | Bad intelligent device or component |
| 13 | Out of calibration |
| 16 | Data valid, but above the normal operating range (moderately severe) |
| 19 | Received network data in error |
| 31 | Condition exists (manufacturer-specific) |
Reading the table
The code column gives the identifier the controller publishes: an SPN/FMI pair or a P-code. The label column gives the short condition or component/failure text from the cited OEM chapter.
A label identifies a monitored circuit or condition. It does not confirm that a named part has failed, and it does not establish whether the machine is safe to operate.
Write down the full code, the model year and model, and the conditions when it appears. That record is what the manual and a service provider use to match the entry to your machine.
Source note
This page publishes short component and condition labels from the public OEM manual chapter, not the manual's long-form repair prose. The source list below opens the exact chapter for every manual in the group.
Scope
This is a label index. It does not provide repair procedures, parts advice, or a diagnosis for a specific machine. Codes can vary by trim, market, and running changes.
Common questions
What does this Ranger 500 / Crew 500 table cover?
This page lists 51 code entries from the cited public OEM chapter (0001025947, 2 manual P/Ns). The table preserves the short condition or component/failure labels published in that chapter.
Where can I check the source?
The source box at the bottom of the page gives the manual P/N, the model-year coverage, and a link to the OEM chapter. The methodology page explains the site’s source and labeling rules.
