The 2014 Volvo V70 XC70 S80 Wiring Diagram TP39264202 Electrical Schematic Manual is the electrical map for three related Volvo platforms sold in left-hand drive and right-hand drive form. Circuits are drawn in the non-active state (key removed, doors, hatches and hood closed) so a technician can follow power, ground and data paths without guessing which contacts should be live.

Vehicles and Variants in This Publication

Cover artwork and running headers identify V70 (08-), XC70 (08-) and S80 (07-). Separate sheets exist wherever body style or steering position changes the harness: tail lamps, brake lamps and reversing lamps are split V70 versus S80; interior lighting, follow-me-home lighting, direction indicators and power windows are split LHD versus RHD; floor, dashboard and infotainment harness drawings are likewise split by model and drive side. Tow-hitch harnesses appear in 4-pin, 7-pin and 13-pin versions for both V70 and S80.

The book also flags market adaptations. Abbreviations list countries and regions (USA, CDN, EU/OS, GB, WEU and others) because Volvo sold legally different lighting and equipment packages. Illustrations that do not apply to every market are still printed; the technician matches the sheet to the car on the hoist rather than assuming every option is fitted.

Powertrains Shown on the Schematics

Engine management, starting, charging, cooling-fan and emission sheets are broken out by cylinder count and fuel:

• 4-cylinder 1.6l Turbo and 4-cylinder 2.0l Turbo
• 4-cylinder Diesel, including Start/Stop 1.6l Diesel DV6C
• 5-cylinder Turbo and 5-cylinder Diesel, with and without Start/Stop
• 6-cylinder, 6-cylinder Turbo and 6-cylinder PZEV

Related power-supply pages cover 4-cylinder Turbo charging, 4- and 5-cylinder cars with Start/Stop (secondary battery 1/2, battery relay 2/166, BMS 7/240) and 5- and 6-cylinder charging without that system. Transmission circuits include manual M66, automatic MPS6 and automatic AWF21, plus the Differential Electronic Module on all-wheel-drive cars. Glow-plug control, fuel-flow valves, EVAP solenoids, variable valve timing solenoids, MAF sensors and heated oxygen sensors appear on the fuse and engine-management pages that match each engine family.

How the Diagrams Are Read

A dedicated “How to use the wiring diagrams” section explains the two-part component code used everywhere in the 2014 Volvo V70 XC70 S80 Wiring Diagram TP39264202 Electrical Schematic Manual. Type number plus serial number produces designations such as 3/2 for a switch or 4/56 for the Central Electronic Module. Type groups printed in the book include battery (1), relay (2), switch (3), control module (4), driver information module (5), electric motor (6), sensor (7), actuator (8), heating element (9), lamp (10), fuse (11), distribution box (15), audio (16), diagnostics (17), contact reel (18), meter (19), ignition component (20), optics (27), ground (31), branching point (73) and connector (74).

The symbol key shows system voltage (drawn in red on the sample sheet), chassis grounds, screened and twisted pairs, CAN H / CAN L, LIN, MOST, DIN/coaxial data, distribution-box taps, inter-harness connectors and in-component connectors. Wire colors use the printed codes BK/SB, BN, BU/BL, GN, GY/GR, LGN, NL, OG/OR, PK/P, RD/R, VT/VO, WH/W and YE/Y. Ignition-switch positions are marked X, S, 15, 15l, 30 and 50. Numbered branching points such as 73/5035 are indexed later so every device hanging on a splice can be listed in one place.

Electrical Distribution, Fuses and Relays

Overview sheets map power from the battery through the engine-compartment box 15/31, passenger-compartment box 15/36, cargo box 15/32 and, on Start/Stop cars, the cold-zone box 15/37. Fuse tables then name every circuit:

• Engine box F1–F44, including 50 A CEM feeds, 60 A cargo and comfort feeds, 100 A PTC element, heated windshield, wiper motor, BCM pump and valves, cooling-fan modules (60 A or 80 A by engine) and 100 A electric power steering
• CEM internal fuses F1–F24 for rear wiper, courtesy lamps, DIM, rain sensor, washers, fuel pump, SRS, ICM/IAM audio, sunroof and ignition switch
• Passenger box F1–F30 for door modules DDM/PDM/LDM/RDM, keyless module, power seats, infotainment, climate damper motors, seat heaters, parking assistance, DEM and Four-C suspension
• Cargo box FA1–FA11 for park-brake module, heated rear window, tow-hitch 13-pin outlet, power tailgate and trailer module
• Battery main fuses PF1–PF2 and cold-zone F1–MF2

IMAGES PREVIEW

Relay pages locate horn, starter, glow-plug, climate clutch, 15-feed, comfort, headlight-washer, heated-rear-window and auxiliary-light relays in the three distribution boxes. Ground overviews then walk 31/2 through 31/AL so a no-ground complaint can be traced to a specific wheel-house, bottom-rail, bumper abutment or roof point instead of a generic “body earth.”

Taken together, those sheets give a technician a complete electrical path from battery and secondary battery through every fuse and relay into the module, motor, lamp or sensor that actually does the work. The component list at the back converts a number printed on a diagram (4/46 ECM, 4/16 BCM, 7/240 BMS, 16/1 IAM and hundreds more) into a plain-language name, while the routing drawings show which harness and which connector family carries that circuit through the car.

Data Networks and Modules

High-speed CAN, a 4-cylinder high-speed CAN variant, intermediate-speed CAN drawn separately for LHD and RHD, LIN and MOST are documented in the control-module section rather than being redrawn on every system sheet. The Central Electronic Module 4/56 sits at the center of comfort and body power. Surrounding modules named in the fuse and component lists include ECM, TCM (TF-80SC and MPS6), BCM, SRS, DIM, SWM, CCM, PSM, KVM, PAM, PAC, TRM, PBM, POT, SUM, DEM, FSM, SCL, HSWM, IAM, ICM, DABM, RDAR and the door modules. That network map is what lets a scan-tool fault on one module be compared with the actual power and bus pins on the wiring page.

Safety Content Printed in the Front Matter

The opening warning covers vehicles with SRS airbags, SIPS bags and inflatable curtains. Work that can affect those systems is directed to an authorized Volvo workshop and to the SRS section of VIDA. The same pages tell the reader how to recognize SRS lettering on the steering wheel and dashboard, SIPS decals, and IC markings on C/D or B panels, and they forbid pinching wires or mounting accessories between A–B, B–C and C–D posts. Those cautions sit in this wiring book because airbag igniters, belt tensioners, occupant weight sensors and curtain igniters all appear later on the Group 88 sheets and on CEM fuse F18.

Use the 2014 Volvo V70 XC70 S80 Wiring Diagram TP39264202 Electrical Schematic Manual on the Job

With this file open you can trace a dead CEM feed back through F1 or F2 in the engine box, confirm whether a Start/Stop car is using the secondary-battery path on page 10, locate the exact ground 31-point under a seat riser, match a trailer-module complaint to cargo fuse FA11, or follow a Dual Xenon or BLIS circuit that only exists on certain option packs. Correct fuse ratings, wire colors and connector numbers stop the common mistakes of swapping a 5 A BCM sense fuse with a 40 A pump fuse or chasing a V70 tail-lamp pin on an S80 harness.

Download is immediate after payment.
