Notes Regarding Replacement Of All Activity Module
After replacement of All Activity Module (AAM)(N10), Hand Held Tester (HHT) must be used in order to version code AAM. The version coding is menu driven. See Fig 1 .
AAM transmitter keys and engine control modules are "married together", meaning that AAM and engine control module must "learn" key code of vehicle. Additionally, AAM "learns" numerous key codes of transmitter key. These assignments can not be changed later on, which means that if AAM is defective the following must be completed to repair the system:
- Order a new AAM, along with a master key, after advising of identification code from your facing PDC.
- Using HHT, reset engine control module and allow engine control module to "relearn".
Additional transmitter keys and replacement of lost transmitter keys requires a "relearning" of AAM. The relearning procedure for new transmitter keys is performed using HHT. To gain access to menu proceed as follows: Body & Accessories - AAM - Control Module Adaption - Transmitter key/Transponder. Only after relearning process is new transmitter key usable.
Prior to using transmitter key, lost old transmitter key must be deactivated. The HHT can be used to determine which keys which are currently deactivated via actual values for "drive authorization".
