Answer 1

Here is the reset procedure.

PROCEDURE TO RESET THE CBS DISPLAY USING THE INSTRUMENT CLUSTER E65 AND E66

The CBS Reset procedure enables resetting of the individual service item. After a service has been performed, the service item must be reset to 100% (full service interval). To reset a service item:

• Insert the Remote Control into the Ignition Lock.

• Press the Start/Stop Button once (KL15 is "On") with foot off the Brake Pedal.

1. Press and hold the Reset Button located on the upper left side of the Instrument Cluster for about 5 seconds.
2. Release the Reset Button when a 4-line menu appears inside the Speedometer display. At the top line is the "Back" function, followed by the first 3 service items. The menu will list the service items sorted by priority of the service due. Note:If the Reset Button is held too long and not released when the above 4-line menu appears, the system will go into Instrument Cluster Test Functions: 01 Identification 02 System test 03 Not used 04 Consumption To exit Test Functions, remove the Remote Control from the Ignition Lock and repeat steps 1 through 4 above.

1. Tap the Reset Button or the lower FAS Button located in the side of the Turn Signal/High Beam Stalk to view the next service items in the menu.
2. Select the Service Item with "!" or "-" by tapping the Reset Button or the lower FAS Button.
3. Press and hold the Reset Button for a few seconds to display a 2-line menu in the Tachometer. The third menu line will appear to confirm if the reset is successful. The nominal interval for the service item will also be highlighted in the Service Need Display (SBA), located under the Speedometer in the Instrument Cluster.

PROCEDURE TO RESET THE CBS DISPLAY USING DISPLUS OR GT1 E65 AND E66

Using the DISplus or GT1, the CBS Reset sets the selected service item to 100% (full service interval) and displays a service counter indicating how many times the service item has been reset.

The CBS reset procedure is found under: Diagnosis - Function Selection - Service Functions - Maintenance- CBS Reset - Test Plan . Then highlight the listed procedure and press the bottom right corner green arrow to the right. The original value of the individual CBS service item will be deleted during the reset procedure.

The first vital step of the reset procedure is to verify the DISplus or GT1 correct date and time: "Are the current date and time correct?" This is important for time and distance-based service items that are managed by the Instrument Cluster, because the internal vehicle trip odometer and vehicle data will be synchronized with the internal Tester data. Confirm by either pressing Yes or No (if required, correct date and time in Main Menu - Administration - DIS - Date/Time). Then select the bottom right corner green arrow to the right.

The next screen offers 3 selection menus:

Selection 1: CBS reset

1. Engine oil
2. Microfilter
3. Front Brakes
4. Rear brakes
5. Vehicle check Selection 2: CBS reset

1. Spark plugs
2. Brake fluid
3. Coolant
4. State Safety inspection
5. Emissions inspection Selection 3: End

To properly complete the CBS reset, the date and time of service/maintenance will be transferred to the vehicle. This includes setting the day counter and the date. The transfer completion is confirmed by: OKAY in the setting status.

The CBS vehicle data correction allows "quick access" to correct or change the basic data stored in the vehicle after the CBS reset. This procedure is found under: Diagnosis - Function Selection - Service Functions - Maintenance - CBS Correction, Vehicle Data - Test Plan . Then highlight the listed procedure and press the bottom right corner green arrow to the right. Please verify the correct date and time of the DISplus or GT1 before proceeding.

The next screen offers 4 selection menus:

Selection 1: Correction

1. Engine oil
2. Microfilter
3. Front brakes
4. Rear brakes
5. Vehicle check Selection 2: Correction

1. Spark plugs
