Segway Powersports fault codes by model

Table map

All 4 pages come from the same 2022 Fugleman UT10 / UT10 Crew owner’s manual and the same chapter, “Diagnostic displays code definitions.” The manual prints one table with a System column; the site splits it into 4 pages because each module has its own code grammar. This map shows the published row count, the first and last printed code, and the printed page for each module.

The 4 pages contain 129 rows in total: the ECU page has 91 (71% of the Segway set), EPS 24, T-BOX 6, and ABS 8. The counts are additive because the 4 records point to 4 different tables; no row is shared across pages.

The ECU sequence begins with P0108 17 and ends with U0121 87. It mixes 88 P rows and 3 U rows. The printed order is the manual’s order, not a numeric sort, so the filter field is more useful than scanning for a code position.

Those 91 ECU rows carry 67 distinct base labels. 5 bases repeat with different trailing values: P0650 (2), P0571 (2), P2106 (5), P1545 (3), and P0606 (17). The trailing set contains 26 values, including 1C and 15 numeric values above 31. The page keeps the suffix in the code cell because the printed value changes the row even when the base label stays the same.

The five most common suffixes account for 54 of the 91 ECU rows: 17 (12 rows), 16 (12 rows), 13 (12 rows), 11 (9 rows), and 12 (9 rows). 16 of the 26 suffixes appear only once. The distribution matters for navigation because the filter matches the full printed cell, not just the base label; a row with a rare suffix is still one row in the table.

The first character of the printed code is the quickest page selector for this manual: P and U rows belong to the ECU page, E rows to EPS, T rows to T-BOX, and A rows to ABS. That rule describes the 4 Segway module groups, not a universal Segway code scheme. On the ECU page the first character is not enough, because the trailing value changes the printed row; the same base label can appear several times.

The repeated labels are not collapsed into one row. P0606 alone accounts for 17 ECU rows, and the other repeated bases account for the rest of the difference between 91 rows and 67 base labels. A reader who searches only the base label will see every printed failure-mode variant, in manual order.

The EPS page is a contiguous E0001–E0024 sequence with one row per code. Its descriptions cover torque-sensor, rotor-angle, current, voltage, memory, CAN, and steering-angle conditions. The T-BOX page has 6 rows for GPS, 4G, Bluetooth, sensor, power CAN, and body CAN. The ABS page has 8 rows: 4 wheel-speed signals, 2 module-voltage rows, vehicle speed, and CAN. These three ranges contain no repeated codes.

The 4-page split is a navigation decision, not a claim that the modules are independent systems. The manual prints one chapter and one table with a System column; the site splits by that column so a reader can filter the 91-row ECU block without paging past the 38 module rows. The source pages explain the arrangement: ECU rows occupy printed pp. 59–62, EPS is on p. 63, and T-BOX and ABS share p. 64.

The table map shows p. 64 twice because the T-BOX and ABS groups are separate System groups printed on the same manual page. Splitting them keeps the module filters separate instead of producing one mixed 14-row list. The same split is why the 4 pages have different first letters but one shared source citation.

Each Segway page uses the label-table layout: one row per printed code, the printed Failure Code cell, and the printed description. There is no separate SPN/FMI group and no FMI glossary on these pages because the ECU suffix is part of the code cell, while the EPS, T-BOX, and ABS codes have no suffix. That layout difference is why the Segway pages look unlike the Polaris SPN/FMI tables.

The archive’s 4 Segway records all carry the 2022 model year. There is no shared canonical Segway table: the 4 module tables have different fingerprints, so the 129 model-code entries and 129 unique rows are the same number. A future Segway year would create a new record or a shared table only if its printed rows matched an existing fingerprint.

The 4 pages cite the same edition, Vision: 20210716, document U09L01000002. The site does not host the PDF, page images, or scanned tables; each page cites the chapter and printed page and reproduces only the printed code and description.

Use the table map when you know which module produced the code. Use the decoder when you only have the code. The All pages directory lists all 4 Segway tables, the other brand hubs, and every guide in one place.
