KEY SPECIFIC SETTINGS HAVE CHANGED

TECHNICAL SERVICE BULLETIN

SUBJECT

Key Specific Settings Have Changed 

MODEL

E65, E66 (7 Series)

SITUATION

The customer may mention any of the following:

• At times the measurement settings switch to Metric (Kilometers, Celsius etc...)
• The Seat and steering column move to an incorrect position or the memory positions have been lost.
• The radio station presets have disappeared or have changed.
• Climate Control settings have changed from previous settings
• Selective unlocking does not operate (all doors unlock /lock with one button push)
• All the doors lock when driving away or doors no longer lock on drive away.

CAUSE

• The customer is using 2 different keys with different stored personalized settings. Most of the time these settings are changed after the vehicle is unlocked with the remote or (if vehicle is not locked), the remote control key is inserted into the Car Access Switch (CAS).
• Certain settings are set to "Inactive" from the factory.

GENERAL INFORMATION

1. Depending on the feature concerned, settings that affect the key are to be found both in "Car Memory," and in "Key Memory." For a listing of all programmable Vehicle/Key Memory (VKM) features on a particular vehicle, access VKM via Coding Individualization Programming (CIP), and view or print the list displayed.
   • "Car Memory" activates or deactivates all keys simultaneously.
   • "Key Memory" is key specific and allows individual activation/deactivation of each key.
2. With the exception of units of measurement (metric units) and radio presets, key specific settings can be activated/deactivated using Vehicle and Key Memory (VKM).

EXAMPLES OF KEY SPECIFIC SETTINGS ARE AS FOLLOWS

• Seat/mirror adjustments will be stored for each key when set to "active." Each key will have different settings stored. For example Driver #1 (Key #1) sets the seat all the way back and down. Driver #2 (Key #2) sets the seat all the way up and more forwards. When each key is used to unlock the car or when the key is inserted into the CAS, then the settings will be restored for each key based on the last position the seat and mirror were in when that specific key was last used.
• Heater and air conditioning settings will be stored for each key when "key selective" is set to "active". Each key will have different settings stored. For example Driver #1 (Key #1) sets the Heater/Air conditioning system temperature at 68°F and set to AUTO. Driver #2 (Key #2) sets the Heater/Air conditioning to 70°F and the vents set to the "center". When each key is used to unlock the car or when the key is inserted in the CAS, the settings will be restored for each key based on the last settings the Heater/Air conditioning were in when that specific key was last used.
• Selective unlocking (single unlock of drivers door when unlock button is pressed on remote control key) can be set to "active" or "inactive" for each key that is used.
• Automatic lock after driving off (all doors lock when vehicle speed is above 5mph) can be set to "active" or "inactive" for each key that is used.
• Radio station memory presets are stored for each key that is used. For example: Driver #1 (Key #1) listens to AM stations and stores these (for example: 660, 880 and 1010) into the memory presets via the iDrive. Driver #2 (Key #2) listens to FM stations and stores these (for example: 92.3, 95.5 and 102.7) into the memory presets of the iDrive. Each time that a specific key is used the radio will resume on the last station that was listened to, and all the memory presets that were stored with that key are available for selection. If the keys are mistakenly switched, the customer may state that the radio station presets are lost. This should be taken into consideration when this complaint is encountered.
• Measurement settings (temperature, distance, etc.) are stored for each key that is used. For example: Driver #1 (Key #1) sets all the settings to metric. Driver #2 (Key #2) sets all the settings to US standard. If the keys are mistakenly switched, the customer may state that his settings switched to metric. This should be taken into consideration when this complaint is encountered.

TROUBLESHOOTING HINTS

• If the customer complains of loss or changes to key memory settings, all keys should be obtained in order to ensure proper diagnosis.
• If possible, request that the customer duplicate his complaint.
• If the customer is mistakenly switching the keys, causing a perception of lost key settings, then the keys should be marked accordingly with the color-coded strips (located in the vehicle portfolio) for easy identification.
• If one key can be identified as causing a problem and all other keys function correctly, then reassign a "key personalization number" to that key as per SI B66 01 02 . Recheck the key function to confirm that the problem is fixed, or continue troubleshooting.
• Using CIP, recheck VKM settings to confirm that all VKM settings are correct.
• If all settings are correct, then the key may be defective and have to be replaced.
