ATTENTION: Tests must be carried out on a dynamometer with two running drums.
If tests are carried out on a dynamometer with two four drums, they are limited to speeds up to 3 miles / hour (5 km/h).
Engine starting
1. Check up work of the traction relay of a starter. Make sure the engine starts normally. Let the engine run.
Starter lock switch - (only for automatic transmissions)
1. Select position 'D' of the automatic transmission selector.
2. Check that the engine does not start.
3. Select position 'R' of the automatic transmission selector and try to start the engine again.
4. Check up a possibility of start of the engine at positions of the selector 'P' and 'N'.
Selector cable - (only for automatic transmissions)
1. Check up correctness of a cable adjustment of a selector of an automatic transmission.
Engine operation and throttle control
1. Start the engine, make sure it starts easily.
2. Make sure the alarms are "oil pressure" And "no battery charge"went out.
3. Be convinced of free, without jammings, movement of a pedal of an accelerator.
4. Make sure the engine "withdraws" to move the accelerator pedal.
Clutch and gear selection
(Only for vehicles with manual transmission, normal driving conditions)
1. Make sure the clutch engages smoothly without jerks, slipping and silently.
2. Be convinced of absence of the extraneous noise proceeding from a transmission.
3. Ensure quiet and easy shifting is possible.
Gear shifting and car parking
(only for vehicles with automatic transmission, normal driving conditions)
1. Establish position 'R' of the selector of a transmission and check up smoothness of starting off of the car.
2. Establish position 'D' of the selector and check up smoothness of gear shifting on higher from the moment of starting off of the car.
3. Stop the vehicle and check for smooth downshifts.
4. Stop the vehicle on a slope.
5. Set the position 'P' selector and release the parking brake.
6. Make sure that the car does not move and the selector does not move out of position "R".
7. Perform the same exercise for the car in the opposite position.
Steering
1. With the vehicle stationary, turn the steering wheel from one end to the other. Check for smooth steering and no abnormal noise from the power steering pump or drive belt.
Car suspension
1. When the car is moving, make sure that there are no extraneous noises, vibrations when driving (e.g. shock absorbers) or wheel imbalance.
Service brake system
1. Check the amount of effort on the brake pedal, the amount of braking distance, the efficiency of the brake mechanisms, vehicle withdrawal and seizure.
Parking brake
1. Pull out the parking brake handle with force, check the stroke of the handle, the holding of the brake pawl and the ease of releasing it.
Devices
1. Check the operation of all devices, indicators and signaling devices.
Body
1. Make sure that there are no extraneous noises coming from the body elements.
Seat belts
1. Check the operation of the inertial coils.
Road test
1. Perform a short road test of the vehicle. Check the adequacy of the operation of all vehicle systems. Pay special attention to:
- Engine noise
- Noises from the gearbox
- Car suspension noise
- car body noise
- The operation of the vehicle's braking system
- Gear shift
- General engine operation
2. If possible, check the operation of the help system (HDC) when moving downhill. If this requires a large distance to be covered, then this check should be omitted.
3. After bench and road tests are completed, carry out a final inspection of the vehicle by lifting it up on a lift.
4. Check the level of all oils, antifreeze and fluids and top up if necessary.
