Ranger Diesel fault codes (2022–2027)
The 2022–2027 Ranger Diesel Tractor / MD manuals publish the same 32-entry diesel-controller diagnostic table. This page lists it once, with the manual citation for each model year and the engine-protection, drive, and chassis circuits behind the codes.
Scope note
This page covers the shared 32-entry table (OEM chapter 0000535756), published in the 2022 Ranger Diesel Tractor (P/N 9940147) and Ranger Diesel MD / Israel (P/N 9940146) manuals and the 2023 (P/N 9940850), 2026 (P/N 9941851), and 2027 (P/N 9942443) Tractor / MD / Israel manuals.
Ranger Diesel machines pair a mechanical drivetrain with an electronic engine controller, so their code list is much shorter than the EFI machines’ lists. The controller’s whole fault list is published here.
Each chapter prints 32 table rows with no repeated keys; the table stayed row-for-row identical across the 2022–2027 manuals.
Table profile
This page reproduces 32 entries from 4 model-year records (2022–2027), 5 manual P/Ns, and chapter 0000535756.
Rows keep the manual’s printed order, from SPN 520207 / FMI 3 to SPN 168 / FMI 4.
Every row carries an SPN/FMI pair; 14 distinct SPNs and 7 FMI values appear.
The largest FMI groups are FMI 4 (11 rows), FMI 3 (10 rows), and FMI 5 (7 rows); together they account for 88% of the table.
The most repeated SPN is 168 (System Power (Battery Potential/Power Input)) with 3 rows, followed by SPN 746 with 3 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, four model years
The 2022, 2023, 2026, and 2027 Ranger Diesel manuals use diagnostic chapter 0000535756. The SPN and FMI rows, labels, and grouping match entry-for-entry across the tractor, MD, Israel, and HD editions. This page publishes the table once and keeps a model-year anchor for each manual.
The per-year URLs from earlier records redirect to those anchors. The table rows are the same; the P/N and model-year citation are not.
What the 32 entries cover
The table covers all-wheel-drive control, brake failure lamp and brake switch, ECU output supply voltages, engine oil pressure and temperature, fan relay, fuel pump driver, gear sensor, glow plug relay, low oil pressure switch, rear differential output, and system power. Most failure labels are supply-voltage or circuit-driver conditions.
The diesel controller faults concentrate on electrical supply and driver circuits rather than engine internals, because the mechanical diesel drivetrain reports fewer electronic conditions than the EFI machines.
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.

Model and year notes
These notes explain which systems matter on each machine. They do not add rows to the OEM table.
Ranger Diesel (2022–2027)
All four model years publish this 32-entry table in chapter 0000535756. The tractor, MD, Israel, and HD editions share the table; the manual P/N and model-year citation differ. Use the anchor for your year.

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.
