Ford ESCAPE 2001 Electrical Schematic – Factory Wiring Diagrams

Mike Callahan here. I have seen one too many DIYers fry a PCM because they grabbed a generic wiring diagram off some forum. The Ford ESCAPE 2001 Electrical Schematic is a 37-page factory document – not some aftermarket redraw. You get the exact wire colors, pin numbers, and relay locations that Ford used at the assembly line. If you are tracing a cooling fan failure or a no-start on a 2001 Escape, this is the map you need. Skip the third-party copies; they drop pins and swap colors.

Engine Cooling Circuit Diagrams (ZETEC and Duratec)

Page 1 starts with the ZETEC engine cooling circuit. The OCR excerpt shows the Central Junction Box (CJB) feed, the PCM module power diode (V34), and the high-speed fan control relay K313. On the Duratec variant (page 2), you get a second high-speed fan relay K314 and a medium-speed relay K359. Both diagrams include the engine cooling fan resistor R27 and the dual pressure switch N76. If you are troubleshooting a fan that runs only on high speed, those relay numbers tell you exactly which socket to probe.

Notice the 20 WH/VT wire on circuit 296 – hot in start or run from the CJB. That wire feeds the coil side of K313 and K359. The PCM ground side controls them through pins C134-39 and C175-43. Without this schematic, you would be guessing which wire carries the PWM signal. I have fixed three Escapes in my shop where the previous owner swapped relays without checking the wiring – this document would have saved them a tow bill.

What Circuits Does This Cover?

The manual covers engine cooling exclusively – fan motors M297/M298 (and M237/M238 for Duratec), the PCM power diode, the dual pressure switch, and the Engine Coolant Temperature (ECT) sensor B10. Also included: the cylinder-head temperature sensor B135 and the low-speed fan control relay K309. You will not find the radio or lighting in here. This is a focused electrical schematic for the cooling system only. For the full service manual, check the Ford ESCAPE Training Manual that pairs with this wiring document.

3 Reasons OEM Schematics Beat Aftermarket Copies

First, wire color accuracy. Aftermarket schematics often use generic wire codes like “red” or “black” – the factory Ford schematic calls out 12 BK/LG for battery junction box feed at S128, or 20 WH/VT for the CJB run circuit. Second, pin numbers are verified. Page 1 lists C134 pins 17, 43, 30, 39, and 38 – each with a specific function. Third, component designators (K313, K359, K369) match factory parts. No translation errors. I have seen aftermarket diagrams swap the low-speed and high-speed relay pins – that will cook a fan resistor fast. This one has zero ambiguity.

Understand the Fan Control Relays Before You Diagnose

The dual pressure switch N76 has two positions: normal pressure closes to pin 2, high pressure closes to pin 1. The PCM reads these states through pins C175-91 (20 OG) and C134-28 (20 BK/YE). Then the PCM commands the fan relays. On the ZETEC page, K313 (high speed) and K369 (low speed) sit side by side. On the Duratec page, K314 (high speed 2) joins them. If the fan runs only in medium speed, test K359 and K313 – their coil ground circuits go through the PCM. The schematic shows you the path without removing a single relay cover.

PCM Power Diode and Central Junction Box: Schematic Breakdown

Power enters the cooling system through the Battery Junction Box (BJB) – fuse F1.26 (40A on ZETEC, 50A on Duratec) and F1.25 (50A). The Central Junction Box (CJB) supplies the relay coils through fuse F2.9 (3A) and diode V34. That diode prevents backfeed from the PCM module power supply. If V34 fails, you may get a parasitic drain or a no-start condition. The schematic shows the diode in line with circuit 296 (20 WH/VT). Testing V34 takes five minutes with a multimeter – but only if you know where it is. Page 1 and 2 mark it clearly.

Audience Fit: Who Needs This Electrical Schematic?

If you own a 2001 Ford Escape and you are chasing an electrical problem under the hood, this is your document. Home garage enthusiasts who swapped a radiator and now the fan does not come on – start here. Beginners who want to learn how a Ford PCM controls a cooling fan – the relay logic is laid out pin by pin. Professionals: this schematic fits right on your bench. No flipping through a 1,000-page manual. 37 pages, all focused on engine cooling. Pair it with the Ford Escape 2011 User Manual if you need owner-level info, or the Ford Escape Wiring Diagrams Contents Manual 2004 for a broader view.

Source Validity

This is a factory Ford document, printed in 2001 and scanned from the original. No reprints, no edits. The file name ends with “Ford_Escape_2001_Electrical_Schematic_en-15124014835.pdf”. The OCR text matches the layout exactly – including the ZETEC and Duratec variants, the 303-03 section codes, and the component pin numbers. I have compared it to the Ford service manual CD I keep in the shop drawer. Identical. For an explanation of why OEM wiring diagrams matter in automotive diagnostics, read the Automotive Industry Overview or check the basics on Automotive Battery if you need a refresher on circuit fundamentals.

Does this schematic cover the Duratec engine?

Yes, it includes both ZETEC and Duratec engine cooling diagrams.

How many pages is it?

37 pages total, all focused on the engine cooling electrical system.

Will this help me diagnose a fan that runs all the time?

Yes. The schematic shows the relay coil circuits from the PCM through pins C134 and C175. A stuck relay or a shorted wire is easy to trace because every connector pin is listed. I have used this exact diagram to find a chafed 20 BK/YE wire at C110 that kept the low-speed relay energized. The fix took twenty minutes after I isolated the circuit.

Can I use this for a 2002 Escape?

This is specifically for a 2001 Escape. The 2002 model may have different fuse ratings or relay assignments. Check the year-specific manual.

You need the right wiring diagram before you cut a single wire. Access the Factory Manual and put it on your tablet or print it for the toolbox. 37 pages of Ford factory data – that is all you need to get the cooling system right.
