08 Youth UTV fault codes: the RZR 200 and Ranger 150 dual-format table How the shared 165-row youth table pairs every P-code with an SPN/FMI reference, why rows cover features the machines lack, and what actually changed in the 2027 edition. Read guide

09 Tractor, MD, and work editions: why Polaris gives them their own tables Why Polaris Tractor, MD, ZUG, and 2-Up editions print their own diagnostic tables: the 72/85/288-row Sportsman ladder, the RZR Trail S work editions, and the work rows that appear only there. Read guide

10 Arctic Cat fault codes: the C, P, and U prefixes and the 2026 Prowler table How Arctic Cat diagnostic display codes are built — C, P, and U prefixes, the 2026 Prowler XT / XT Crew table, the FUEL OFF entry, and the separate EPS section codes. Read guide

A group of snowmobilers running a wide snowy expanse in bright winter light.

11 Polaris E-VES codes: the exhaust valve module P1400 series explained What the E-VES exhaust valve module is, the three valve positions, the sixteen P140x diagnostic rows, and why break-in can set these codes. Read guide

12 Ranger Diesel fault codes: the compact 32-row table explained How the Polaris Ranger Diesel diagnostic table is organized — component rows, the FMI 3/4/5 driver pattern, the glow plug rows, and the CAN timeout row. Read guide

13 The condition column: how FMI sorts one Polaris component into several rows How the FMI condition number splits one Polaris component into several published rows: the 3/4/5 ladders, FMI 31 condition-established families, and the out-of-band FMIs the manuals print. Read guide

14 Same Polaris code, different label: wording changes, meaning shifts, and how to verify 78 Polaris P-codes print two or more labels across the published tables — wordings, qualifiers, and six true meaning shifts (P1407, P1408, P1511, P1610, P2630, P2632) — and the two-number check that tells them apart.

How to use the guides

The model pages are lookup tables. The guides explain the structure around them: how a code is formatted, why a table can change between model years, why a supply event can produce several entries, and what the states of a code mean. They are written to be read before or alongside a lookup, not as a substitute for the cited OEM chapter.

If you already have a code, start with the decoder or the model-year page. If you have a symptom but no code, the symptom map can help you identify the table families worth reading. If you are comparing two model years, the model-year guide explains how the fingerprint and the manual P/N work.

Each guide cites the code families and model groups it discusses. The guides do not provide repair procedures, parts recommendations, or a diagnosis for a specific machine. The OEM manual for the machine is the source for model-specific service information.

What the guides cover

Code formats. SPN/FMI and P-code structure, and why the same number can map to a different circuit.
Table structure. Shared chapters, model-year fingerprints, and the manual P/N citation.
Code clusters. Why a supply event can produce entries in more than one controller.
Code states. Active, stored, and history, and what clearing changes.
Symptom mapping. How common complaints relate to the code families in the published tables.
Reduced-power strategies. What the manuals describe and which inputs are associated with them.
Manufacturer prefixes. How the Arctic Cat C/P/U families map to table rows, and where its separate EPS section fits.
Module and diesel tables. Why an exhaust valve module gets its own chapter, and how a 32-row diesel table repeats rows by condition level.
Snowmobile platform tables. Why one snowmobile badge maps to four different main-code tables plus two separate chapters, and where the same code carries a different label.
Youth dual-format rows. How the shared RZR 200 / Ranger 150 table pairs every code with an SPN/FMI, and what the 2027 edition relabeled.
Work-edition tables. Why Tractor, MD, and 2-Up manuals print their own chapters, from the 2022 predecessor tables to the 288-row work-edition set.
Condition column. How the FMI number sorts one component into several rows, from the 3/4/5 ladders to FMI 31 and the out-of-band FMIs.
Label variance. Why the same printed code can carry two names — wording changes, qualifiers, and the six true meaning shifts.
Network rows. The receive, transmit, bus, and pair-loss entries across the published tables, and the five CAN message PGN rows.
