911 Turbo (996) Alarm system I 48 96 96-5Control module function Communication with seat memory control module The two control modules "seat memory" and "alarm system" com- municate via a signal lead. This realises adjustment of the mirror and seat positions via the hand-held transmitter. If required posi- tions of the rearview mirrors and driver’s seat are assigned to a hand-held transmitter, the rearview mirrors and driver’s seat move to these positions as soon as the vehicle is unlocked with the hand- held transmitter. The PST2 can be used to test the communication line between the two control modules for an open circuit. Procedure: 1. Connect PST2 and switch on ignition. 2. Select "Seat memory" control module 3. Select "Alarm system interface level" in the menu item "Input signals" 4. Press the locked/unlocked button of the hand-held transmitter The switch position on the PST2 is closed briefly. Activation status memory The alarm-triggering components that are in the non-active state during alarm system activation and that are therefore blocked for alarm triggering are stored in the activation status memory. The activation type also is saved. If the vehicle is secured, e.g. by remote control, and the oddments tray is open, this is indicated by the alarm system control memory by a brief horn signal. This status is stored in the activation status memory under "Oddments tray acti- vation type: - by remote control-". This function can be used in trou- bleshooting, inasmuch as a faulty micro switch or faulty wire can be the cause for the horn signal. Reading out the activation status memory can help to track down the faulty alarm-triggering compo- nent, e.g. front lid, rear lid, oddments tray, etc. Coding Four functions can be selected under menu item "Coding:": ♦Country coding ♦Version coding ♦Vehicle re-locking ♦Alarm siren/tilt sensor 9601 Control module function 96-5 page 1 Printed in Germany – 4, 2001 sgf_xi48
