Xenon Headlight Testing

Xenon headlight systems (control module, igniter and bulb) produced prior to 9/98 can be tested with Special Test Adapter (P/N 90 88 6 631 000) in conjunction with the DIS Pre-set Measurements System.

The DIS Measuring System includes all of the cable connection information and procedures for the test.

Scheme 197

Generation III Xenon lights on vehicles produced after 9/98 are tested with a different tool. Xenon test adaptor P/N 90 88 6 631 010 is used along with DIS/MoDiC preset measurements "Xenon lights after 9/1998".

The Generation III test adaptor uses the 50 amp test cable with both the MoDiC or DISplus.

Scheme 198

Scheme 199

In addition to the Measurement System tests there are also Test Modules available in the Diagnosis Program to diagnose vehicles with Generation 3 Xenon lights.

MID Self Test

The MID test function is activated by pressing the first and last menu buttons while switching the ignition on. The following items can be tested.

Unit Identification - This information appears for approximately 3 seconds when the ignition is switched on. The ID information displayed is

Scheme 200

1. Hardware number.
2. Software number.
3. Variant index.

All other test functions must be activated while the ID information is displayed. If this is not done, the MID test is cancelled after the ID information is posted.

Display Test: Activate this test by pressing the display menu button. All elements of the main and menu displays are illuminated with different check patterns.

Button test: Start the test by pressing the button test menu button. All the buttons on the MID have been assigned an alphabetical letter that will appear when the button is pressed.

Volume control test: The test is carried out by pressing the menu button and turning the volume knob. Numbers from 01 to 36 appear on the display indicating each step of knob rotation.

Status LED test: Activate the test by pressing the menu button. All status LEDs are illuminated.

On-Board Computer (BC)

The processing and display of the on-board computer functions is carried out by the IKE.

The IKE receives and evaluates all of the BC required data. The BC functions can be called UP for display on the MID or the Instrument Cluster matrix.

The following BC functions are available for display.

1. Time.
2. Date.
3. Average speed.
4. Range.
5. Distance.
6. Arrival Time.
7. Average fuel consumption.
8. Limit.
9. Timer/Stopwatch.
10. Code.

The outside temperature measurement is not a BC function. The temperature is continuously displayed in the instrument cluster and is used to activate the freeze warning.

Operation of the MID can be checked through the test function sequence on the MID panel.

Scheme 204

The following items can be checked

UNIT IDENTIFICATION - The following information appears for approximately 3 seconds when the ignition is switched on

1. Hardware number.
2. Software number.
3. Variant index.

All other test must be started within three seconds, while the identification data is displayed. If not the MID will exit the test mode.

DISPLAY TEST - Activate this test by pressing the display menu button. All elements of the main and menu displays are illuminated with different check patterns.

BUTTON TEST - Start this test by pressing the button test menu button. All buttons on the MID have been assigned an alphabetical letter that will appear when the button is pressed.

STATUS LED TEST - Activate this test by pressing the menu button. All status LEDs are illuminated.

DIAGNOSIS/ENCODING

Diagnosis of the GR II system is carried out with the DIS tester. The cruise control module stores faults that occur with the input/output signals for cruise control operation. The Multi-Function steering wheel control module stores faults that occur with the cruise control switch.

There is only one control module for all model versions that use the new GR II system. Encoding is required if the control module is changed. To code a new control module, go to the coding application in DIS and carry out a coding procedure as stated on the screen.

An uncoded module will allow limited cruise control operation.

Radio Test Functions

With the ignition switch in KL R the radio can be switched into the test function mode by pressing and holding the WB (weather band) until the MID displays a serial number in the MID main display.

The test functions include

1. Radio serial number.
2. Road speed dependent volume control (GAL 1 --4).
3. Radio Production Date.
4. DSP Recognition.
5. Station signal strength.

The road speed dependent volume control can be adjusted to make the volume increase more audible (4) or less audible (1).

Radio Test Function

To activate the test, switch the radio on and within 8 seconds press and hold the "m" button for more than 8 seconds. The displayed tests include

1. Radio Serial Number.
2. Station signal Strength.
3. Radio Production date
4. Road speed dependent volume control (GAL 1 --4).
5. DSP Recognition (1/0).

Adjusting the GAL makes the volume increase more noticeable (4) or less noticeable (1).

Diagnosis

The PDC system is connected to the diagnostic link through the I-Bus/K-Bus.

The DIS is used for diagnosis and troubleshooting procedures when faults occur with the system.

Fault Symptom troubleshooting paths should be used to troubleshoot failures with the PDC system.
