2006 Acura MDX Service & Repair Manual (OEM)

• Applies to 2003–2006 Acura MDX repair work, with year-specific splits wherever the service information changes. The complete system-wiring and advanced engine-performance diagnosis volumes are 2006-specific, navigation coverage is for 2005–2006, and power-lumbar information applies to 2004–2006 Touring models.
• Engine sections cover removal and installation, compression and VTEC rocker-arm testing, valve-clearance adjustment, timing-belt service, cylinder-head and camshaft repair, valve and guide work, crankshaft and piston service, bearing selection, oil-pump overhaul, and cooling-system repair.
• The powertrain-management files document PGM-FI, fuel supply, EVAP, EGR, VTEC, PCV, intake-air, ignition, and idle-control systems, with HDS/PCM troubleshooting, sensor and actuator replacement, circuit checks, freeze-data use, monitor logic, and DTC fault isolation.
• Transmission coverage distinguishes the MDKA 2003–2005 and BDKA 2006 five-speed automatics, including DTC and symptom diagnosis, road, stall, and hydraulic-pressure testing, solenoid and speed-sensor service, transfer-assembly work, transmission removal/installation, ATF-cooler cleaning, and shift-cable adjustment.
• Chassis material includes front, rear, and intermediate driveshaft service, propeller-shaft inspection, VTM-4 rear-differential diagnosis and control-unit initialization, conventional brake repair, VSA troubleshooting, steering pressure tests and gearbox overhaul, and front/rear suspension work.
• SRS coverage reaches post-deployment inspection, driver/passenger/side/side-curtain airbag service, cable reel and impact-sensor replacement, OPDS initialization, front-passenger weight-sensor calibration, and separate 2003 versus 2004–2006 component layouts.
• Electrical and accessory sections break out connector locations, fuse/relay systems, charging, starting, lighting, gauges, security, power windows, locks, mirrors, seats, moonroof, audio, rear entertainment, and navigation, with Bose/non-Bose and other equipment-specific circuits where provided.
• Tooling references identify items such as the EQS02BMDXSB0 front-subframe adapter, 07VAJ-P8A010A VTEC air adapter, 07MAC-SL0A102 ball-joint remover, 070AZ-SAA0100 SRS short canceller, KTC trim tools, HDS functions, and system-specific pressure-test adapters.

Coverage and File Structure

The set contains 4,714 PDF pages in 73 topic-organized files. Its largest volumes are SRS, 565 pages; automatic transmission, 457; 2006 advanced diagnostics, 381; PGM-FI, 291; electrical component locations, 172; cylinder head, 164; 2006 system wiring diagrams, 159; power steering, 157; audio, 134; axle shafts, 127; EVAP, 123; navigation, 120; VSA, 114; fuel and emissions, 110; and rear differential, 100. The remaining 58 files account for 1,540 pages and cover the smaller engine, chassis, body, electrical, and accessory sections.

This is a topic-split service-information archive rather than one continuously paginated Acura book. Most core PDFs are Mitchell Repair Information exports, and many component illustrations are credited within the files to American Honda Motor Co., Inc. That distinction matters for buyers expecting a single bound factory publication or one publication number.

Diagnostic and Repair Depth

The 381-page 2006 advanced-diagnostics volume contains 179 diagnostic entries covering 189 named DTCs, supported by 267 numbered figures. Each entry explains the monitored component or control strategy, then gives monitor execution, enable conditions, malfunction thresholds, MIL and freeze-frame behavior, and clearing logic. Coverage runs from MAP, IAT, ECT, throttle, A/F and HO2S circuits through fuel trim, misfire, catalyst, EVAP, EGR, electronic throttle control, transmission monitoring, VTEC, and F-CAN communication faults.

Representative references include the five-part 3.5L Engine Performance Circuit, MAP sensor output-voltage graphs, the gear-position-to-shift-solenoid table, the FCAN bus-off circuit, VTM-4 and VSA communication diagrams, and SRS/OPDS circuit and component views. The separate specifications file adds standards and service limits for the engine, transmission, rear differential, steering, suspension, brakes, and air conditioning without forcing the technician to hunt through unrelated chapters.

The automatic-transmission section is strongest on diagnosis, hydraulic testing, external controls, transfer service, complete removal/installation, cooler cleaning, and shift-mechanism work. It does not provide a complete internal transmission teardown and rebuild sequence. Air-conditioning coverage is likewise limited to wiring and specification references rather than a full HVAC repair chapter. Both are important scope points when selecting this set for a planned repair.

Repair Cautions

The manuals flag several easy-to-miss failure points. The upper and lower front-brake caliper pins are not interchangeable; installing them in the wrong positions can cause vibration and uneven or rapid pad wear. A replacement VTM-4 control unit must be initialized or the 4WD system will not operate correctly, and residual debris in an uncleaned ATF cooler can cause a repeat failure after a replacement or remanufactured transmission is installed.

Engine removal, SRS work, brake/VSA service, pressurized fuel and power-steering diagnosis, and transmission cooler cleaning require the correct lifting, isolation, diagnostic, and protective equipment. Repairs beyond the user’s training or shop capability should be handled by a qualified technician.
