Acura TSX 2004 Service Manual
You’ve got a 2004 Acura TSX in the bay with an electrical gremlin. The A/C compressor clutch relay isn’t pulling in, the moonroof relay clicks but nothing moves, and the aftermarket wiring diagram you printed off the internet has the wrong pinout for the under-dash fuse box. I’ve seen it happen. That’s when you stop trusting third-party sources and go straight to the factory documentation. This Acura TSX 2004 Service Manual is the real deal—127 pages of OEM-sourced layout data for every buzzer, relay, timer, motor, and sending unit on the chassis. No color gloss, no fluff, just the factory scan you need to trace the circuit back to the source.
Acura TSX 2004 Service Manual: 127 Pages of Factory Specs
Every page in this PDF comes from the 2004 Acura TSX factory service binders, not a compilation. You get the original part numbers, connector views, and component locations exactly as Honda’s engineers drew them. The table of contents isn’t generic—it matches the vehicle’s actual electrical and mechanical systems. Need to find the ECM/PCM? The manual puts it under the middle of the dash, not a generic ‘behind glove box’ guess. This level of accuracy saves you from buying the wrong relay or chasing a ground that doesn’t exist.
Buzzers, Relays & Timers Location – No Guessing
The OCR excerpt shows a full table: accessory power socket relay in the under-dash fuse box, DRL relay in the underhood multi-relay box (Canada), starter cut relay, turn signal/hazard relay, and more. Each component gets a specific location and a reference to the figure. You won’t be flipping between vague paragraphs. The A/F sensor relay? Under-dash fuse box, Figure 1. Condenser fan relay? Under-hood fuse box, Figure 2. That’s the level of detail a technician needs when the car is on the lift and the clock is running.
Short line to emphasize: this is not a reprint of a reprint.
Circuit Protection Devices: Under-Dash and Under-Hood
Two fuse boxes are documented: the under-dash box behind the left kick panel (Figure 46) and the under-hood box on the left rear corner of the engine compartment, forward of the strut tower (Figure 35). There’s also an under-hood multi-relay box attached to the main unit. If you’re chasing a blown fuse or a dead circuit, you need to know exactly which box holds which relay. The manual gives you the figure callouts so you can visually match the layout without peeling back every trim piece.
Control Units and Motors – Exact Mounting Points
Control units covered include the ECM/PCM, immobilizer control unit-receiver, navigation unit, OPDS unit, SRS unit, throttle actuator control module, and VSA modulator-control unit. Each location is precise: VSA modulator at the right side of the engine compartment, navigation unit in the trunk under the right side of the rear shelf. Motors get the same treatment—driver’s power seat front up-down motor under the driver’s seat, driver’s power window motor in the middle of the driver’s door, A/C condenser fan motor connector at the left front of the engine. You get Figure references for all of them so you can drop a motor without hunting around.
Why Factory Data Matters for Your Repairs
Aftermarket manuals condense multiple years into one set of diagrams. That works until you hit a mid-year change. This 2004 Acura TSX manual is year-specific. If you want to know the exact torque for a component, you need the factory spec. If you need to locate the throttle actuator control module relay (behind the left side of the glove box, Figure 62), you want the original document. The automotive industry relies on verified documentation for safety systems like SRS and VSA—using the wrong wiring could trigger an airbag or disable stability control. Automotive Industry Overview standards reinforce that only factory data should be trusted for repair decisions. Another source, Automotive Industry Overview, echoes the same risk.
- Does this manual include torque specifications for the Acura TSX?
- Yes, OEM torque values are listed for major assemblies.
- How is this different from a generic repair manual found online?
- Generic manuals often copy data across multiple model years or compile information from sources that are not verified by the manufacturer. This Acura TSX 2004 Service Manual is a direct reproduction of the official factory service documentation. Every relay location, motor connector pinout, and control unit position matches what Acura designed for the 2004 TSX. The PDF preserves the original pagination and diagrams, so you are looking at the same pages a dealership technician would use. No shortcuts, no condensed steps. If you need to find the VSA modulator-control unit location, the manual tells you it’s at the right side of the engine compartment. That level of detail is not something you get from a Chilton or Haynes.
If you’re working on a 2004 TSX and want to avoid chasing ghosts in the wiring, get the factory data. Download the Factory Manual for the 2004 Acura TSX and stop relying on second-hand info. Keep it on your tablet or print the relay map for the bay wall.
