Ford CD345, CD340 2009 Electrical Schematic – OEM Factory Wiring Manual

If you are chasing a short in a Ford CD345, CD340 2009 Electrical Schematic and you are using third-party wire colors, you are losing time. I have seen techs swap SJB modules because an aftermarket diagram labeled a ground as a 12V feed. That mistake costs hours and parts. This is the factory set – 135 pages of Ford’s own electrical circuit schematics for the CD340 and CD345 platforms. Delivered as a clean PDF, not a scan of a scan.

135 Pages of Ford-Specific Circuits

The manual opens with an index page (page 1) and a log file of changes (page 2). From there, it dives straight into power distribution. Page 3 starts the 1A CD34X POWER DISTRIBUTION SJB GEN-2 sheet 1/2. Every sub-system is mapped with the exact connector pinouts, wire gauges, and splice locations Ford used on the line. You get:

• Electrical distribution for EJB variants: DW10, DW12, LYNX, 15T, 14 2.0, 14 2.3, 14 SIGMA, 2.0 GTDI (DISI), DW10C, and RJB (pages 5–14).
• Grounding sheets on pages 26–29 – four separate sheets for chassis, engine, and interior points. Miss one ground reference and the whole DEATC system can act up.
• Start/cranking circuits (page 30) with KV control – essential for diesel CD340 models with smart charge systems.
• Manual A/C, single zone rear A/C, dual electronic automatic temp control (DEATC) for both CD340 and CD345 (pages 79–82).
• Power window circuits, sunroof, sunblind, mirror memory, seat maneuvering, seat climate, rear seat heating (pages 85–93).
• Alarm, keyless unlocking, central locking front/rear/w.o. rear DCU (pages 95–99).
• Audio, navigation, amplifier, Bluetooth, rear seat entertainment (pages 100–105).

What Power Distribution Sheets Are Covered?

This is where most aftermarket compilations fail. They give you one generic “power distribution” page and call it done. This Ford manual separates power distribution by engine and body controller. The 1A CD34X PD EJB PETROL sheets 1 and 2 (pages 15–16) show the exact fuses, relays, and feeds for petrol variants. Separate sheets exist for diesel (pages 24–25). You also get the PD RJB (page 17) and PD SJB GEN-2 for engine compartment, floor, IP, and roof (pages 18–20). If you need the EJB layout or SJB layout GEN 2, those are on pages 21–23. Ford CD345 2006 Technical Manual covers earlier engine management, but this 2009 schematic is the one for modern body electronics.

Get the Right Wiring Data – OEM vs. Aftermarket

Aftermarket electrical schematics often use generic symbols and guess wire colors. Ford’s factory document uses the exact wire codes, connector views, and component locations from the production line. I have seen aftermarket diagrams show a solid red wire for a circuit that Ford runs with red/yellow stripe. That one stripe difference can send you down a wrong harness. This manual includes the layout sheets for EJB, SJB, and RJB so you can physically locate the connector and pin. Ford ESCAPE 2001 Electrical Schematic – Factory Wiring Diagrams is another example of OEM quality, but the CD345/CD340 manual is specific to those platforms. Ford ESCAPE 2001 Electrical Schematic – OEM Factory Wiring Manual may share some generic diagrams, but do not mix platforms – use the right one.

Who Needs This Manual?

If you are a home garage technician working on a 2009 Ford CD340 minibus or CD345 passenger van, this is your wiring bible. Professional shops that service fleet vans should have this on every bay PC. The manual covers the MY10.50 electrical architecture (Job#1) and includes all subsystem schematics from power distribution through audio. Beginners should not guess on electrical repairs – this manual gives you the real circuit paths and component IDs. Automotive Industry Overview confirms that OEM documentation reduces diagnostic time by 40% compared to generic sources. Automotive Battery systems are detailed in the grounding sheets, so you can trace high-current draws correctly.

Source Validity – Factory Ford, Not a Reprint

This is a direct PDF of the original Ford publication (PHAG9T-70000-AB, date 09/11/03). It is not a copy, reprint, or third-party interpretation. The document includes the revision log, original Delphi signatures, and CAD dates. Every sheet carries the Ford part number prefix. If a torque spec or connector type is needed, it is in the schematic notes. I have used these exact pages to diagnose DEATC failures on a CD345 that had no heat – turned out to be an open ground on page 28.

Does this manual cover both CD340 and CD345 models?

Yes. The index clearly states “CD340 + CD345” and separate sheets are provided for each where they differ (e.g., DEATC for CD340 vs CD345).

Can I use this for a 2010 model?

This 2009 manual covers the MY10.50 production start (Job#1). 2010 models may have running changes. Check the log file on page 2 for schematic changes – if your VIN falls within the range, the circuits are identical. For later revisions, look for a 2010 supplement.

Chasing electrical problems without a factory schematic is like putting a timing chain on without a block holder. You might get it, but you risk smoking a module. This is the real OEM content – 135 pages of Ford CD345 and CD340 wiring. Stop using diagrams that give you the wrong pin. Access the Factory Manual and trace the circuit the way Ford designed it.
