2027 Arctic Cat 400 (Bearcat, Jag, M, Pantera, XF) fault codes

What the 39 rows contain

The P block has 35 rows. It covers intake-air and coolant temperature, throttle position, engine over-temperature, cylinder 1 injector, knock control, ignition coil A, exhaust temperature, oil-pump and injector programming, regulator and fuel-pump voltage, oil-pump outlier, speed sensor, knock activation, crank-angle sensor, exhaust-valve position and actuator, engine RPM, barometric pressure, P2600 coolant-pump control, and control-module shutdown. The U block has 4 rows: lost communication with the suspension control module and the LCD gauge, plus vehicle registration messages.

P2600 is the row that separates this table from the 600.858 sequence. The manual prints the description with quotation marks around “A” and a slash between “Circuit” and “Open”; the page preserves that text.

The six 400 models behind one book

Bearcat 400 LT and Pantera 400 are the utility and touring names; Jag 400, Jag 400 Special, M 400, and XF 400 cover the trail and crossover names. The manual prints one table for all six. The page keeps the full table rather than inferring which rows a particular model can set.

How the 400 table relates to the 600.858 table

The 400 table is nearly a subset of the 600.858 table. 38 of its 39 codes appear in the 600.858 sequence; P2600 is the only addition. The 600.858 book prints 28 codes that the 400 book does not, including the C-family suspension and warmer rows and the exhaust-valve, navigation-display, and P1004/P1261/P1264 rows. The 400 page stays separate because the book, model list, and citation are different.

What the table does not include

The table prints a code and a short description only. It does not print an SPN/FMI pair, a fault-setting condition, a healing condition, a wiring diagram, a test procedure, or a parts list. The page therefore has no FMI glossary and no condition columns. It also does not expand a code into a repair step or a safety determination.

This book has no EPS table. A C13xx code is not part of this sequence. The 600.858 and 4 Stroke books publish a separate EPS table on the shared snowmobile EPS page.

How to use this page

Record the exact code, confirm the model year and model name, and note the manual P/N and printed page. The table below keeps the manual's order, and the filter can search by code or by a word from the description. The 600.858 page covers the larger main table.

This page is a label index. It does not provide repair steps, parts advice, or a diagnosis for a specific machine. Codes can vary by trim, market, and running changes, so the cited manual remains the source for the exact machine.
