2004 DAF LF45, LF55, C65, CF75, CF85, XF95 Service Manual (P/N DW23259202–DW23259602)

• 13 PDF files totaling 2,880 pages of DAF factory workshop documentation, with publication and revision codes spanning 2002–2005. The set centers on LF45/LF55 repair, maintenance, electrical diagnosis, DAVIE XD testing, and special tools. Identified DAF publication numbers include DW23259202–DW23259602, DW13279204, DW23262905, and DW232830.
• Engine and fuel coverage matches BE 99 C, BE 110 C, BE 123 C, CE 136 C, CE 162 C, and CE 184 C builds. Factory procedures cover valve and timing checks, cylinder-head and complete-engine removal/installation, crankshaft seals and sensor rings, cooling and lubrication testing, ECS-DC3 fuel diagnosis, injector/rail/high-pressure-pump service, turbocharger inspection, and engine-brake adjustment.
• Transmission, clutch, and prop-shaft sections distinguish mechanical and pneumatic controls, ZF S5-42, ZF 6S-850, Eaton FS/6309A, Allison 1000/2000, and Allison MD 3060 configurations. Coverage includes fault finding, control adjustment, transmission removal, seal and bearing service, clutch bleeding, and universal-joint disassembly/reassembly.
• Brake, steering, axle, and suspension repair covers fully pneumatic brake diagrams; Wabco PAN 17, PAN 19-1+, PAN 19-2, and Knorr SB7000/SN7000 disc brakes; brake-performance and equalization checks; F36/F48, F60, and 152N front axles; steered trailing axles; rear axle types 5.10, 5.12, 5.14, 8.20, 10.20, 10.26, and 11.26; and leaf- or air-suspension layouts.
• Cab and maintenance procedures address day and sleeper cabs, complete cab removal, tilting-pump and lifting-cylinder work, heater/dashboard/door/glass/seat service, scheduled inspections, fluid and lubricant specifications, filter replacement, system bleeding, and chassis lubrication.
• Electrical documentation provides short-circuit, open-circuit, and ground-fault diagnosis; multimeter/scopemeter signal testing; CAN and connector repair; pin and component locations; and circuit diagrams 1427090/03 and 1427090/04 with chassis changes at 0L247507, 0L248731, 0L252611, and 0L253643.
• The 280-page 2004 DAVIE XD diagnostics volume, P/N DW23262905, applies to LF45, LF55, CF65, CF75, CF85, and XF95. It covers fault codes, customer parameters, and system inspections for EBS/EBS-2, UPEC, AS Tronic, VIC, ECAS-2/3, ECS-DC3, and related modules. Key procedures include UPEC engine-brake and speed-variation tests, AS Tronic transmission and clutch-actuator menus, EMAS and ECAS calibration, CDS-3 unit initialization, EBS-2 VSC calibration, and ALS-S radar-sensor inspection.

Repair Depth and Configuration Detail

The electrical book is especially useful when a truck sits near a production change. Diagram 1427090/04 begins at chassis 0L247507, followed by revisions at 0L248731 for LF45 VIC connector and harness details, 0L252611 for CDM-related circuits, and 0L253643 for ECS-DC3/exhaust-brake inputs. Component-location tables, connector views, pin assignments, and focused schematics for the CAN network, VIC, ECS-DC3, ABS/ASR, ECAS, and automatic transmission help match the circuit to the actual build before testing starts.

The mechanical volumes combine troubleshooting with factory inspection, adjustment, removal, and installation procedures. Engine chapters extend through cylinder-head, timing, flywheel, seal, cooling, lubrication, and complete-engine work. Chassis coverage reaches wheel ends, steering geometry, steering hydraulic tests and bleeding, brake dynamometer checks, cab-tilt hydraulics, suspension links, and separate LF55 air-suspension arrangements for the 13–15-ton and 16–18-ton GVW ranges.

A separate special-tools book indexes DAF tool codes by vehicle series and component. Examples tied to the repair procedures include 1240080/1240081 for engine oil-sump pressure inspection, 1329476 for Voss fuel-line test connections, 1329464 for mini-ALR load-sensing-valve adjustment, and 1329495 for Knorr SN-series disc-brake overhaul work. The index shows where a factory repair assumes dedicated tooling before disassembly begins.

Diagnostics and Coverage Boundaries

The principal workshop groups are written for LF45/LF55 trucks. CF65, CF75, CF85, and XF95 coverage belongs to the DAVIE XD diagnostics volume; the special-tools publication also lists additional older F-, CF-, and XF-series applications. That broader model list should not be read as full CF/XF mechanical repair coverage across the complete set.

The BE/CE engine volumes provide major component removal, top-end service, timing, seals, and system testing, but they do not contain a full crankshaft, piston, or connecting-rod overhaul chapter. The transmission volume covers operation, diagnosis, controls, removal/installation, seals, and adjustment work, but not a complete internal gearbox rebuild. AS Tronic appears in the DAVIE diagnostic material rather than as a mechanical overhaul chapter; prop-shaft universal-joint disassembly is documented separately.

Two repair traps are called out repeatedly. Dirt introduced during ECS-DC3 injector, rail, or high-pressure-pump work can damage precision fuel-system parts, while the wrong injector washer or clamping orientation can cause internal leakage or engine damage. In the electrical chapters, using the test/signal ground as a component ground or making an incorrect crimp can produce malfunction, broken insulation, loose conductors, or a short circuit.

Because these manuals cover pneumatic brakes, high-pressure fuel equipment, cab tilting, steering, rotating driveline parts, and pyrotechnic restraint circuits, repair work should be performed with the vehicle secured, pneumatic and hydraulic pressure released, the cab correctly supported, and electrical systems isolated as directed by the factory safety sections.
