System operation in armed mode
After arming, the system monitors the status of the following security zones:
- side doors;

Table 7-17. List of fault codes SDUEP
For the diagnosis of SDUEP, a diagnostic device DST-2M or DST-10 is used (12). Diagnostic tool in system selection «Electrical package» allows you to view fault codes in the mode «Faults», system parameters in mode «Options», and manage individual devices (interlock gearmotors, horn relay) in mode «IM management».
