Honda Ridgeline 2006–2008 Service Manual (P/N 61SJC02)

Honda’s factory service manual for the 2006–2008 Ridgeline (P/N 61SJC02, first edition, June 2007) covers U.S. RT, RTS, and RTL models, with RTX coverage for 2007–2008. Canadian coverage includes LX and EXL. The model charts distinguish EXL SR and the applicable moonroof, XM radio, and navigation configurations.

Searchable Chapters and Diagram Detail

Text search and navigation: All PDFs contain searchable text. The embedded bookmarks use numbered labels, and some links have invalid destinations. Small pin numbers and wire-color codes in dense wiring diagrams are easier to read when zoomed in.

The ZIP contains 23 printable chapter PDFs totaling 2,372 pages. That count includes three introductory pages, seven chapter-specific SRS precaution pages, and four otherwise blank pages.

V6, VTM-4, and Ridgeline Body Service

These selected procedures and references show the scope of the manual. Other topics include windshield replacement and propeller shaft service.

• Engine repair: Step-by-step engine removal and installation, timing-belt service, cylinder-head repair, and crankshaft, piston, and bearing inspection for the J35A9 V6.

• Fuel and emissions: PGM-FI fault isolation, electronic throttle control diagnosis, fuel-pressure testing, and PCM replacement with idle learn.

• Transmission and 4WD: BJFA road, stall, and hydraulic pressure tests, plus transmission removal, valve-body service, shaft and clutch repair, and VTM-4 rear differential diagnosis.

• Steering, suspension, and brakes: Power-steering pump and gearbox overhaul, wheel alignment, hub and bearing service, brake bleeding, caliper overhaul, and VSA diagnosis.

• Tailgate and pickup bed: Latch synchronizer and hinge-latch service, In-Bed Trunk and bed component replacement, moonroof work, and frame repair data.

• Electrical and restraints: System-specific circuit diagrams, connector and terminal views, B-CAN fault isolation, and model-year-specific SRS diagnostic and calibration procedures.

Honda wrote this manual for qualified professional technicians. Its service precautions address raised-vehicle drivetrain tests, pressurized fuel, brake work, and refrigerant handling, and Honda directs SRS service to an authorized dealer.

Maintenance, Engine Tests, and Emissions

The Maintenance Minder section explains main and sub-items, indicator reset, and specified lubricants and fluids. It identifies where trailer towing, low-speed mountain driving, or frequent fully loaded operation calls for different service intervals.

Engine procedures include compression and VTEC rocker-arm tests, valve-clearance adjustment, valve-guide replacement, valve-seat reconditioning, and cylinder-bore honing. The lubrication chapter pairs oil-pressure testing with oil-pump overhaul. The cooling chapter covers radiator, fan, thermostat, and water-pump checks.

Fuel and emissions coverage extends to readiness codes, injector and sensor replacement, and diagnosis of the EVAP, EGR, PCV, and catalytic converter systems.

Transaxle, Rear Differential, and Chassis Controls

Transmission troubleshooting uses the Honda Diagnostic System (HDS) for DTCs and includes shift-solenoid, pressure-switch, shift-cable, and interlock checks. Internal service covers backlash and carrier bearing preload in the A/T differential, plus transfer assembly inspection and adjustment. The symptom charts help a technician decide whether to investigate a control fault, check hydraulic pressure, or inspect a clutch.

Honda flags a main seal seated too deeply because it can block the ATF return passage. The manual also identifies the risk of damaging the torque converter housing during main bearing work or seizing the ATF pump during valve-body assembly.

VTM-4 coverage includes HDS and manual control-unit initialization, rear differential function tests, fluid-temperature sensor service, differential removal, and backlash inspection. The chassis chapters add steering pressure and rack-guide checks, damper and spring service, TPMS sensor ID memorization, and VSA center-point writing and sensor diagnosis.

Wiring, Climate Control, and Restraints

Circuit examples cover the Starting System, A/T Gear Position Indicator, VTM-4, TPMS, Heating/Air Conditioning, and SRS. The body electrical chapter maps power and ground distribution and includes control-unit input tests, keyless transmitter programming, power-window reset, gauge self-diagnosis, odometer and Maintenance Minder data transfer, compass calibration, and immobilizer registration. Honda’s standalone Electrical Troubleshooting Manual is a separate publication.

HVAC procedures include refrigerant leak and pressure testing and climate control self-diagnosis. The audio and navigation chapter covers error codes, sound-quality troubleshooting, navigation diagnostic mode, and forced display startup.

The restraints chapter distinguishes the 2006 OPDS from the 2007–2008 ODS and seat-weight sensor setup. It covers initialization and calibration, operation checks, post-deployment inspection, airbag and tensioner replacement and disposal, cable-reel service, and impact and roll-rate sensor replacement.

Service References and Honda Tools

Exploded assembly indexes and component locations accompany torque callouts, pressure-test specifications, fluid capacities, adjustment data, and service limits. Tool references include the VTEC air adapter 07VAJ-P8A010A and the A/T clutch pressure gauge set/panel 07406-0020400 or 07406-0020401. The tailgate procedures identify the height step gauge 07AAG-SJCA100 and left hinge alignment fixture 07AAG-SJCA200 for setting tailgate fit.

Valve Clearance and Stall Speed Examples

For the J35A9, Honda specifies 0.20–0.24 mm intake clearance and 0.28–0.32 mm exhaust clearance when the cylinder head is below 100 °F (38 °C).

For the BJFA, the stall test lists a nominal 1,950 rpm and a service range of 1,800–2,100 rpm in D, 2, 1, and R at normal engine operating temperature with the A/C off.
