BASIC REPAIR HINT
This section describes basic points that the service operator must understand before performing the service operation.
1. APPEARANCE
- Always wear clean work clothing.
- Wear a cap and protective shoes.
2. PROTECTION OF VEHICLE UNDER MAINTENANCE AND PREPARATION OF TOOLS/EQUIPMENT
- Before work, cover the vehicle body. (Ex. grille cover, fender cover, seat cover and floor mat cover)
- Before performing the service operation, prepare tools, equipment, container box, grease and cloth etc.
3. SAFETY
- Before work, set the wheel stoppers to secure the vehicle.
- When performing work by multiple workers, call to each other to make sure that service operation is performed safely.
- Before starting engine, ventilate the room.
- When performing the service operation of high-temperature parts like muffler, rotating parts like fan and other movable parts, be careful not to get burned or injured.
- For the jack-up and lift up, set the tool to the proper location to support the vehicle correctly. And use the safety device properly when lifting up.
4. SERVICE OPERATION
- By identifying the vehicle problems thoroughly before work, service operation will be performed effectively.
- Before removing parts, confirm the installation condition or the damage of the parts.
- To reinstall parts properly, leave a note of the condition before work as necessary.
- For a part which needs positioning, take appropriate action such as putting alignment marks.
- For a removed part, clean it as necessary and check for damage and defect before installation.
5. REMOVED PART
- A removed part must be organized to avoid mixing up with similar parts. When same parts are used in multiple locations, such as pistons in engine, manage the parts by using labels with cylinder No. so that the parts are not installed to the wrong location.
- Always replace nonreusable parts such as gasket and O-ring with new parts.
- After work, have a customer confirm the replaced part.
6. WHEN REMOVING BATTERY
When removing battery, power supply is cut off and the information stored in the computer memory is volatilized. Therefore, setting information of some device is initialized to the factory default. The device and functions initialized by removing battery are as follows.
- Clock display of multi-function display (MFD)
- Set temperature of fully automatic air conditioner
- Automatic full open/close of driver's window (power window needs to be initialized)
- User setting items in the audio and navigation systems
- Past trouble history (memory code)
NOTE
This is the information that can improve the efficiency of maintenance and assure the sound work.
1. FASTENERS NOTICE
Tighten the bolts and nuts to the specified torque. Do not apply paint, lubricant, rust retardant or other substance to the surface around bolts, nuts, etc. It may cause troubles with tightening to the specified torque and result in looseness and other problems of bolts and nuts.
2. STATIC ELECTRICITY DAMAGE
Do not touch the control modules, connectors, logic boards and other such parts when there is a risk of static electricity. Always use a static electricity prevention cord or touch grounded metal for the elimination of static electricity before conducting work.
3. BATTERY
When removing the battery terminal, always be sure to turn the ignition switch to OFF and remove the battery ground cable first.
4. BACKUP/POWER SUPPLY FUSE
Backup fuse (20A) remains removed to prevent the battery consumption when vehicles are delivered. Install the backup fuse by following the illustration. Besides, installing the backup fuse deactivates the control during shipping (delivery mode).
5. IMMOBILIZER RELATED PART
Do not replace parts which have immobilizer ID (all ignition key, combination meter (except for Canada), body integrated unit, ECM and SCM (for Canada)) with the parts from other vehicle.
6. SERVICE PARTS
Use genuine parts for maximum performance and maintenance when conducting repairs. Subaru/FHI will not be responsible for poor performance resulting from the use of parts except for genuine parts.
7. PROTECTING VEHICLE UNDER MAINTENANCE
Make sure to attach the fender cover, seat covers, etc. before work.
8. ENSURING SECURITY DURING WORK
When working in a group of two or more, perform the work with calling each other to ensure mutual safety.
9. LIFT AND JACK
When using a lift or shop jack to raise a vehicle or using rigid rack to support a vehicle, always follow instructions concerning jack-up points and weight limits to prevent the vehicle from falling, which could result in injury. Be especially careful that the vehicle is balanced before raising it. Be sure to set the wheel stoppers when jacking-up only the front or rear side of the vehicle.
CAUTION: Select the lift attachment so that the side sill does not contact the lift arm.
NOTE:
- When using a lift, follow its operation manual.
- When the side sill cover contacts the lift arm, use a lift attachment.
- God not work or leave unattended while the vehicle is supported with jack, support it with rigid racks.
- Be sure to use the rigid racks with rubber attached to cradle to support the vehicle.
- When using a lift, use an attachment or something similar.
- When using a plate lift, use a rubber attachment. Place the attachment to the specified position of the vehicle, by adjusting front/rear and left/right sides accordingly.
- Align the cushion rubber center part of plate lift with the center part of rubber attachment.
- God not use the plate lift whose attachment does not reach the supporting locations.
- Support locations
- Pantograph jack
- Lift
CAUTION: For models with side under skirt, use a spacer or an attachment to lift up the vehicle securely at jack up point, without contact of side under skirt and lift.
- Rigid rack
- Plate lift
- Jack-up point (when using a garage jack)
CAUTION: If jacking up the front side of the vehicle, make sure that the jack is attached at the center of the jack-up plate not at the sides.
10. TIE-DOWNS
Tie-downs are used when transporting vehicles and when using the chassis dynamo. Attach tie-down only to the specified locations on the vehicle.
- Tie-down location
- Chain direction at tie-down condition
CAUTION:
- Pull the front and rear of the vehicle in the opposite direction, and pull the left and right of the vehicle in the same direction.
- Patterns except for the followings (recommended) are not allowed.
- Tie-down range
For ground transportation
CAUTION: When the vehicle is tied down from vehicle inside, hook the hooks of tie-down chain on the rear tie-down hooks from vehicle inside. When the vehicle is tied down from vehicle outside, hook the hooks of tie-down chain on the rear tie-down hooks from vehicle outside.
For sea transportation
CAUTION: The eye bolts are exclusively used for towing and sea transportation tie-down, and do not use them for ground and freight transportation.
- Vehicle sinking volume at tie-down condition
CAUTION: The vehicle sinking volume at tie-down condition should be less than 50 mm (1.97 in) and make sure to fix the vehicle securely.
Check to see if the tensions of chains or belts at tie-down condition are appropriate in the following procedures.
1. Before tie-down, measure the distance between the highest tire point and highest arch point at the center of wheel.
2. After tie-down, measure the distance between the highest tire point and highest arch point at the center of wheel.
3. If the distance (A) between the measured value of 1) and 2) above, is less than 50 mm (1.97 in), it is judged as OK. If the distance is 50 mm (1.97 in) or more, it is judged as NG because the tension is too high.
- Notes for the use of tie-down hook
When the vehicle is tied down from vehicle inside, hook the hooks of tie-down chain from vehicle inside, and when the vehicle is tied down from vehicle outside, hook the hooks of tie-down chain from vehicle outside. For front tie-down hook, use S hook and J hook, and for rear tie-down hole, use S hook, J hook and T hook. T hook can be used only for rear tie-down hole.
11. TOWING
Avoid towing vehicles except when the vehicle cannot be driven. For models with AWD, CVT or VTD, use a loader instead of towing. When towing other vehicles, pay attention to the following to prevent hook or vehicle damage resulting from excessive weight.
- Do not tow other vehicles with a front tie-down hook.
- Make sure the vehicle towing is heavier than the vehicle being towed.
- Front
Remove the hook cover, and install the towing hook (eyebolt).
- Rear
Remove the hook cover, and install the towing hook (eyebolt).
- Precautions
CAUTION:
- Place the shift lever in "N" position during towing.
- Do not lift up the rear wheels to avoid unsteady rotation.
- Turn the ignition key to "ACC", then check the steering wheel moves freely.
- Release the parking brake to avoid tire dragging.
- Since the power steering does not work, be careful for the heavy steering effort. (When engine is stopped)
- Since the servo brake does not work, be careful that the brake is not applied effectively. (When engine is stopped)
- In case of the malfunction of internal transmission or drive system, lift up four wheels (on a trailer) for towing.
- Do not use towing hook (eye bolt) except when towing.
- Make sure to detach the towing hook (eye bolt) after towing. If the hook remains attached, airbag may not operate properly when receiving a shock from front side.
12. CARRIER CAR
Before lowering the vehicle from the carrier car, perform the following operations.
CAUTION: Always perform the following operations before lowering the vehicle from the carrier car. Otherwise, the power unit will rotate reversely, which may cause the damage to the engine, vacuum pump, and transmission.
- Start the engine.
- Set the transmission shift position into driving direction of the vehicle. (When the vehicle drives forward, do not set the transmission into R range. When the vehicle drives rearward, do not set the transmission into 1 - 5 speed, or D range.)
CAUTION: Be sure to perform 2) mentioned above even if the engine cannot be started in some reasons.
13. FRONT HOOD STAY
1. Always attach the stay to the normal position when performing works such as inspections and general maintenance.
CAUTION: At the inspection and general maintenance, do not detach the stay.
2. When wider front hood opening is necessary, set the stay to the lower position (hood hinge) as shown in the figure.
14. GENERAL SCAN TOOL
Using general scan tools will greatly improve the efficiency of repairing engine electronic throttle controls. Subaru Select Monitor can be used to diagnose the engine, VDC, air conditioner and other parts.
15. AWD CIRCUIT MEASURES
1. Full-time AWD MT model
Since viscous coupling (limited slip differential) is used in the center differential, cut-off of AWD circuit cannot be carried out.
2. Full-time AWD CVT model
Since electronically controlled MP-T hydraulic multi-plate clutch is adapted for center differential, switch to FWD by using Subaru Select Monitor.
16. SPEEDOMETER TEST
1. Rear wheel free roller system
1. Set the free roller on the floor of rear wheel side securely according to the wheel base and rear tread of the vehicle.
2. Let the vehicle ride on the tester and free roller gently.
CAUTION: Fix the vehicle using a pulling metal (chain or wire) to the front and rear towing hooks or tiedown hook to prevent the lateral runout of front wheels and springing out of vehicle.
3. Set the speedometer tester.
4. Conduct the speedometer test work.
CAUTION: Do not operate the clutch quickly and do not accelerate or decelerate suddenly during work.
2. Rear wheel jack-up system
1. Set the vehicle on speedometer tester.
CAUTION: Fix the vehicle using a pulling metal (chain or wire) to the front and rear towing hooks or tie-down hook to prevent the lateral runout of front wheels and springing out of vehicle.
2. Jack up the rear wheels and set the rigid racks to the specified locations of side sill.
3. Conduct the speedometer test work.
CAUTION: Do not operate the clutch quickly and do not accelerate or decelerate suddenly during work.
17. BRAKE TEST
1. Full-time AWD MT model
1. Perform this test after driving the vehicle 2 to 3 km (1.24 to 1.86 miles) on road in order to stabilize the viscous torque of viscous coupling.
2. Keep the front or rear wheels on the ground for this test.
NOTE: Effect of the viscous torque on braking force will be added approx. 25 kg compared with FWD model.
3. When the brake dragging force is large.
- Check the dragging of brake pad or brake shoe.
- Since it may be affected by the viscosity of viscous coupling, jack up either of the front or rear two wheels to check the each wheel rotation condition with the viscous coupling affection removed.
2. Full-time AWD CVT model
1. Keep the front or rear wheels on the ground during measurement.
2. When the brake dragging force is large.
- Check the dragging of brake pad or brake shoe.
Specifications:
- When measurement is difficult to carry out because both of front wheels are locked, break force measurement in this condition conforms to standard grand total.
18. ON THE CAR WHEEL BALANCING
CAUTION:
- Carry out the procedures after measuring the balance of each single tire.
- Set the vehicle so that the front and rear wheels are the same height.
- Release the parking brake during measurement.
- Rotate each wheel by hands, and make sure it rotates without dragging.
- Do not operate the clutch quickly and do not accelerate or decelerate suddenly during work.
- When an error is indicated during engine drive, do not use the motor drive together.
1. Set the rigid rack to the specified locations of side sill, jack up the front or rear two wheels of non-measuring side and set the pickup stands to two wheels of measuring side.
2. For drive wheel, drive the tires with engine for measurement.
3. For non-drive wheel, drive the tires from the on the car wheel balancer for measurement.
