How to Calibrate Mercedes Airmatic control unit by Autel DS708

How to troubleshoot a Mercedes-Benz S-Class that lowers itself when parked?

In some cases, the car will drop itself overnight but not always. If the vehicle is parked on an incline or downhill the raising or lowering may stop working. There are many reasons lead to this malfunction. Mercedes-Benz with airmatic suspension tries to level itself when parked and end up with lowering near to the ground. But the vehicle may try to level itself unsuccessfully when one level sensor is broken, or the rod is bent. This may cause your Mercedes-Benz self-level too high or too low.

What’s the Symptoms?

The following problems may occur on Mercedes-Benz E, C, CLK, GL, S-Class

-You hear air compressor engaging when parked.

-Air compressor releases air when parked.

-Car lowers overnight, not always.

-Mercedes lowers drops on rear or front.

-Mercedes raises itself when parked

Cause

When the car is parked the airmatic will try to level the car. It does this by discharging air from the airmatic suspension strut that is too high. Typically the MaxiDAS DS708 is leveled by lowering the one or two corners of the car that are too high. We also have seen cases when an incorrect installation of the level sensor caused the airmatic trying to level the car by increasing air pressure at certain strut, therefore, raising the car to the maximum setting.

The cause of this problem is usually one of the level sensors. Each of these sensors has two hall effect sensors inside.

B22/8 Left Front Level Sensor

B22/9 Right Front Level Sensor

B22/3 Rear Axle Level Sensor

The two front level sensors are located at the air suspension struts. In some models, you will only find one sensor at the rear axle. In this case, it measures the position of the torsion bar which provides an average vehicle height for both rear wheels. Mercedes – suspension – airmatic – strut

The level sensors measure the current height of the vehicle, and those reading are stored on the airmatic control unit.

How to solve Mercedes-Benz raises or lowers when parked?

The level sensors measure the current height of the vehicle, and those reading are stored on the airmatic control unit.

So, you need to do:

1.inspect the level sensors first

1)Inspect the front level sensors.
make sure there is no bending of the arm, no damaged of the wires. If you performed any suspension repair ensure that the level sensor at the front airmatic strut is not installed backward.

2)Inspect the level sensor at the rear torsion bar.
Ensure the connecting rod is not bent.

2.If the sensors do not have any physical damage, your next step is to carry a vehicle level calibration.

you can pay to do level calibration in a workshop, or you can perform it yourself if you have a scanner capable of performing airmatic troubleshooting. You will need a scanner that provides similar capabilities to Mercedes Star Diagnostic and allows you to scan multiple control systems in your Mercedes-Benz including programming, actuating and calibrating sensors.

Below is how to access the airmatic control unit and calibration using the Autel MaxiDAS DS708 diagnostic scanner.

Step1: Choose vehicle information

GM Tech2 clone program ECU with SPS in TIS2000

Here is the step-by-step instruction on programming GM (General Motors) ECUs with Tech2 scanner and SPS (Service Programming System) application in TIS2000.

NOTE:

Before using the SPS, make sure that the GM Tech 2 Scan Tool and the pc contain the latest software, the battery of the vehicle is fully charged, only the ignition is on power,
and all cables are connected properly. TIS2000 will not work on 2007 up GM, and software must work together with TIS2000 USB key. If you need to program Saab ECU,
you had to use Saab TIS2000 and USB dongle.

Main steps:

Step 1: Instruction for TIS2000 software

Step 2: Data request

Step 3: Data exchange

Step 4: Program ECU

Alternative Programming with “Pass Thru”

Check Programming result

Step 1: Instruction for TIS2000 software

1.Connect the Tech II to the pc.

Note: The hardware key (HWK) has to be registered prior to working with ‘Service Programming System’. To register a hardware key, the form that is enclosed with
the hardware key kit has to be filled in and sent to the address at the top. In case the form is missing, the document is also in the TIS 2000 newsletter (see icon in the
TIS 2000 tool bar). At first, the user receives a temporary code until the key is registered on the next TIS 2000 CD.

Hardware keys that have already been registered are still valid!

To register the hardware key select ‘Hardware Key Registration’ in the menu ‘Configuration’.

TIS2000 installation video guide

2.Start TIS 2000 on the pc.

3.Select the application ‘Service Programming System’ on the TIS 2000 start page.

4. On ‘Select Diagnostic Tool and Programming Process’ (picture below) screen make the desired selection for

1) the used Tech2 diagnostic tool

2) the reprogramming of an ECU that was not exchanged or the replacement/programming of a new ECU

3) the ECU location.

9-1

5.Click “Next” button to continue.

Step 2: Data Request

1) Connect Tech 2 scanner to vehicle. Power on device – “Tech 2” is displayed on the screen, then press “ENTER”.

2) Turn ignition to ON without start the engine!!!

3) Select “F1: Service Programming System (SPS)” in the main menu.

4) Press “F0: Request Info” on Tech 2.

5) If Tech 2 has already stored vehicle data they will be displayed now. In that case, Tech 2 asks you to either use the current data (hold data) or request further information from the ECU (continue).

6) For the selection of “Next” the vehicle has to be identified as requested by OBD II Scanner Tech 2.

Note: Depending on the model year and the selected model either a reprogramming of the ECU (F0: Engine) or of the TCM (F1: Transmission) can be selected.

7) During the Request Info the Tech 2 receives information from the selected device. If the ECU was replaced a “Request Info” has to be performed for the NEW unit. Since the new ECU is not programmed on delivery, the retrieved information is not complete. For that reason, TIS 2000 gives instructions as how to enter the missing vehicle data.

8) Follow the instructions on the Tech 2. Then press “Exit” on the Tech 2, switch it off and disconnect it from the vehicle.

Step 3: Data exchange

1.Connect Tech 2 to the pc, switch it on, and click on ‘Next’ on the pc.
2.Confirm VIN or, if necessary, enter correct VIN, then select ‘Next
3.Validate vehicle data and, if necessary, change with the pull-down menus
