Service Precautions

4WD model Information


The 4WD CR-V does not have the feature that mechanically switches between 4WD (four-wheel drive) and 2WD (front-wheel drive).

Do not drive the vehicle with rear wheels on the ground even though the front wheels are off the ground. The front wheel power is conveyed to the rear wheels, and the vehicle will start off.

Always lift the vehicle up so all four wheels are off the ground when troubleshooting, testing and inspecting the vehicle to rotate the wheels.

Use the free rollers under the rear wheels when performing test the vehicle with the speedometer tester.

Precautions on using free rollers:


  • Inspecting and testing using a chassis dynamometer is not feasible.
  • Do not operate the accelerator pedal, brake pedal or steering wheel abruptly. It may cause the vehicle to roll and create a hazardous condition.
  • The maximum testing speed should be 50 km/h (31 mph).
  • The maximum continuous operating time should be 3 minutes.
  • Make sure to tie down the vehicle securely with the side anchor wires. The free rollers are to be set under the rear wheels.



  • Make sure to place the free rollers parallel to the roller of each speedometer tester.
  • Putting the front and rear wheels on the speedometer testers and free rollers inappropriately may cause the vehicle to roll off or over the free rollers and create a hazardous condition.
  • The side anchor wires must be appropriately tensioned. If the wires have too much slack, the expected tie-down efficiency cannot be obtained.
  • When attaching the side anchor wires, make sure they are not interfering with the bumper and other parts of the vehicle body.
  • Do not attach the wires to any place other than the designed areas.
  • Do not a operate the speedometer testers at a speed more than 50 km/h (31 mph) or for more than 3 minutes.

Speedometer Testing Procedures

1.Set the free rollers according to the wheel base and tread of the vehicle.

 

2.Move the vehicle to position the front wheels on the speedometer testers and the rear wheels on the free rollers. Make sure to align the center of the wheels to the center of the speedometer testers and the free rollers.

 

3.Tie down the vehicle securely using the towing hooks to prevent the vehicle from rolling off or over the free rollers.

4.Start the engine, shift the transmission to 3rd gear (manual transmission) or to [D] position (automatic transmission), accelerate the vehicle gradually, and measure the vehicle speed.

5.After measurement, use the brake pedal to gradually decelerate and stop the vehicle.

General




Observe all safety precautions and notes while working.

  • Protect all painted surfaces and seats against dirt and scratches with a clean cloth or vinyl cover.

 

  • Work safety and give your work your undivided attention. When either the front or rear wheels are to be raised, block the remaining wheels securely. Communicate at frequently as possible when work involves two or more workers. Do not run the engine unless the shop or working area is well ventilated.

 

  • Before removing or disassembling parts, they must be inspected carefully to isolate the cause for which service is necessary. Observe all safety notes and precautions and follow the proper procedures as described in this manual.

 

  • Mark or place all removed parts in order in a parts rack so they can be reassembled in their original places.

 

  • Use the special tool when use of such a tool is specified.

 

  • Parts must be assembled with the proper torque according to the maintenance standards established.

  • When tightening a series of bolts or nuts, begin with the center or large diameter bolts and tighten them in crisscross pattern in two or more steps.

 

  • Use new packings, gaskets, O-rings and cotter pins whenever reassembling.

  • Do not reuse parts that must be required to replace. Always replace them.

 

  • Use genuine HONDA parts and lubricants or those equivalent. When parts are to be reused, they must be inspected carefully to make sure they are not damaged or deteriorated and are in good usable condition.

 

 

  • Brake fluid and hydraulic components
    • When replenishing the system, use extreme care to prevent dust and dirt from entering the system.
    • Do not mix different brands of fluid as they may not be compatible.
    • Do not reuse drained brake fluid.
    • Because brake fluid can cause damage to painted and resin surfaces, care should be taken not to spill it on such materials. If spilled accidentally, quickly rinse it with water or warm water from painted or resin surfaces.
    • After disconnecting brake hoses or pipes, be sure to plug the openings to prevent loss of brake fluid.
    • Clean all disassembled parts only in clean BRAKE FLUID. Blow open all holes and passages with compressed air.
    • Keep disassembled parts from air-borne dust and abrasives.
    • Check that parts are clean before assembly.

 

  • Avoid oil or grease getting on rubber parts and tubes, unless specified.

  • Upon assembling, check every part for proper installation and operation.

 

Electrical Troubleshooting Information


Before Troubleshooting

1.Check applicable fuses in the appropriate fuse/relay box.

2.Check the battery for damage, state of charge, and clean and tighten the connections.



  • Do not quick-charge a battery unless the battery ground cable has been disconnected, otherwise you will damage the alternator diodes.
  • Do not attempt to crank the engine with the battery ground cable loosely connected or you will severely damage the wiring.

3.Check the alternator belt tension.

Handling Connectors

  • Make sure the connectors are clean and have no loose wire terminals.
  • Make sure multiple cavity connectors are packed with grease (except watertight connectors).
  • All connectors have push-down release type locks (A).

 

  • Some connectors have a clip on their side used to attach them to a mounting bracket on the body or on another component. This clip has a pull type lock.
  • Some mounted connectors cannot be disconnected unless you first release the lock and remove the connector from its mount bracket (A).

 

  • Never try to disconnect connectors by pulling on their wires; pull on the connector halves instead.
  • Always reinstall plastic covers.

 

  • Before connecting connectors, make sure the terminals (A) are in place and not bent.

 

  • Check for loose retainer (A) and rubber seals (B).

 

  • The backs of some connectors are packed with grease. Add grease if necessary. If the grease is contaminated, replace it.

 

  • Insert the connector all the way and make sure it is securely locked.
  • Position wires so that the open end of the cover faces down.

 

Handling Wires and Harnesses

  • Secure wires and wire harnesses to the frame with their respective wire ties at the designated locations.
  • Remove clips carefully; don't damage their locks (A).

 

  • Slip pliers (A) under the clip base and through the hole at an angle, then squeeze the expansion tabs to release the clip.

 

  • After installing harness clips, make sure the harness doesn't interfere with any moving parts.
  • Keep wire harnesses away from exhaust pipes and other hot parts, from sharp edges of brackets and holes, and from exposed screws and bolts.
  • Seat grommets in their grooves properly (A). Do not leave grommets distorted (B).

 

Testing and Repairs

  • Do not use wires or harnesses with broken insulation. Replace them or repair them by wrapping the break with electrical tape.
  • After installing parts, make sure that no wires are pinched under them.
  • When using electrical test equipment, follow the manufacturer's instructions and those described in this manual.
  • If possible, insert the probe of the tester from the wire side (except waterproof connector).

 

  • Use a probe with a tapered tip.

 

  • Refer to the instructions in the Honda Terminal Kit for identification and replacement of connector terminals.


  • Puncturing the insulation on a wire can cause poor or intermittent electrical connections.
  • For testing at connectors, bring the tester probe into contact with the terminal from the connector side of wire harness connectors in the engine compartment.
    For female connectors, just tough lightly with the tester probe and do not insert the probe.


When checking any control module(s) or unit(s) connector terminals, gently slide the sharp tester probe from the wire side into the connector until it comes in contact with the terminal end of the wire.

 

Five-step Troubleshooting


1.Verify The Complaint
Turn on all the components in the problem circuit to verify the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area.

2.Analyze The Schematic
Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power feed through the circuit components to ground. If several circuits fail at the same time, the fuse or ground is a likely cause.

Based on the symptoms and your understanding of the circuit operation, identify one or more possible causes of the problem.

3.Isolate The Problem By Testing The Circuit
Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible.

4.Fix The Problem
Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures.

5.Make Sure The Circuit Works
Turn on all components in the repaired circuit in all modes to make sure you¢ve fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on the fuse. Make sure no new problems turn up and the original problem does not recur.
