Diagnostic testing unit, connecting

Special tools, testers and auxiliary items required

Scheme 4

Scheme 4: Diagnostic testing unit, connecting
  1. Vehicle Diagnosis, Testing and Information System VAS 5051 B

Scheme 5

Scheme 5
  1. Vehicle diagnosis service syst. VAS 5052 or later testers

Scheme 6

Scheme 6
  1. Diagnostic cable VAS 5051/6A
WARNINGDuring a test drive you must always secure testing and measuring equipment on the back seat. Drivers must NEVER operate these tools while driving.

Installation position of diagnostic connector

Installation position of diagnostic connector on vehicles --> 09.00 VEHICLES --> 09.00

Installation position of diagnostic connector on vehicles 10.00 --> VEHICLES 10.00 -->

Perform vehicle system test

  1. Connect the diagnostic unit, --> «Diagnostic testing unit, connecting»(ref-255362-S17681944162007053000000) .
  2. Switch ignition on.
  3. Select operating mode "Guided Fault Finding" on the display.
  4. Then perform vehicle identification on tester.

Program now performs a vehicle system test automatically and checks for all possible control modules for this vehicle type.

  1. Press Continue > button.

Now all DTCs will be listed.

Note. At this point it makes sense to switch into operating mode Guided Functions in order to perform further work using VAS 5051 and to prevent a second vehicle identification on the tester. To do so, press operating mode button and then Guided Functions. Refer to the corresponding work descriptions for the continued sequence. In order to return to Guided Fault Finding, press the operating mode button and then Guided Fault Finding.

WARNINGIn any case, the vehicle must be returned to the customer with DTC memory erased.

Static malfunction

If one or more static malfunctions are stored in data memory, it is recommended to arrange with the customer to repair this malfunction via Guided Fault Finding.

Sporadic malfunctions

In the event only sporadic malfunctions or notes are stored in DTC memory and the customer has made registered no complaint in conjunction with an electronic vehicle system, erase DTC memory.

  1. Press the Continue > button again to enter the test plan.
  2. Now end Guided Fault Finding via Go to button and then End.

All DTC memories will be checked now once more.

The window that now appears confirms that all sporadic faults were cleared.

Then the diagnostic protocol is sent "online" or stored on the tester.

Note. If tester is not connected to the network, diagnostic protocol is stored and the transmission follows as soon as tester is connected to the network. Protocols that have been stored and are older than four days are erased automatically.

Vehicle system test is completed.

CV joint boots, visual inspection

Perform the following work procedure

Scheme 7

Scheme 7: CV joint boots, visual inspection
  1. Visually inspect outside CV joint boots - 1 - and inside CV joint boots - 2 - for leaks and damage.

Note. For vehicles with All Wheel Drive (AWD), also check joint bellows at rear axle.

Perform test drive

To what extent the following can be checked is dependent upon the vehicle equipment and local conditions (urban/country).

The following should be checked by means of a road test

  1. Engine: Output, misfiring, idling speed, acceleration
  2. Clutch: Pulling away, pedal pressure, odors
  3. Gear selection: Ease of operation, shift lever position
  4. Automatic transmission: Selector lever position, shift lock / ignition key interlock, shift behavior, display in instrument cluster
  1. Foot and parking brake: Function, free travel and effectiveness, pulling to one side, juddering, squeal
  2. ABS function: When braking with activated ABS, the brake pedal must pulse noticeably.
  3. Steering: Function, steering free play, steering wheel centralized when wheels are in straight ahead position
  4. Sunroof: Function
  1. Radio, Radio/Navigation system: Function, Reception, SCV, interference
  2. Multifunction indicator (MFI): Functions
  3. A/C system: Function
  4. Vehicle: Moving off line when traveling straight ahead (level road)
  1. Imbalance: Wheels, drive shafts, prop shafts
  2. Wheel bearings: Noises
  3. Engine: Hot starting behavior

Checking headlight setting (with new test screen without 15 ° -setting line)

Headlights

Check the following

Scheme 8

Scheme 8: Checking headlight setting (with new test screen without 15 ° -setting line)
  1. With the low beam switched on check whether the horizontal light-dark border of the setting line - 1 - contacts the test surface.
  2. Check whether the break-away point - 2 - between the left horizontal part and the rising part on the right of the light-dark border runs vertically through the center point - 3 -. The bright core of the light beam must be on the right of the vertical line.

Note. To make it easier to find break-away point - 2 - cover and uncover left half of headlight (as viewed when looking forward) a few times. Then check low beam again. After correct adjustment of low beams the center point of the main beam must lie on the center mark - 3 -.

Scheme 9

Scheme 9
  1. For the previous test screens with 15 ° setting line, adjust for new test screen. But to avoid incorrect settings ignore 15 ° -setting line.

Scheme 10

Scheme 10

Fog lights (vehicles 10.00 --> )

Note. On vehicles --> 09.00, adjustment of fog lights occurs automatically with adjustment of headlights.

  1. Check whether the upper light-dark border touches the setting line horizontally over the complete test screen width.
