Function to output audible alarm signals - GF54.30-P-2013PM
MODELS 203.0 /2 /7 as of 24.4.04 audible turn signal indicator
Acoustic turn signal indicator (A1h2)
The audible turn signal indicator (< > h2) is integrated in the instrument cluster (A1)A1. The turn signal flasher is always accompanied by an acoustic clicking sound generated in the same rhythm. The audible turn signal indicator (A1h2) is actuated differently depending on the function.
Flashing alarm
The signal to actuate the audible turn signal indicator (A1h2) during hazard warning flashing comes from the front SAM control unit with fuse and relay module (< >) via the Controller Area Network bus class B (interior) (CAN-B)N10/1. For this purpose the front SAM control unit with fuse and relay module (N10/1) receives a corresponding message from the upper control panel control unit (N72/1).
Turn signal indicator flashing
The signal to actuate the audible turn signal indicator (A1h2) during turn signal indicator flashing comes from the rear SAM control unit with fuse and relay module N10/2 via the CAN-B
If one of the turn signals fails, the "audible turn signal indicator" (A1h2) is actuated at twice the usual frequency. The instrument cluster (A1) receives the information about the defective turn signal lamp from the front SAM control unit with fuse and relay module (N10/1) or from the rear SAM control unit with fuse and relay module (N10/2) via the C-ANB.
Flashing for special functions with code (450) taxi version
The signal to actuate the audible turn signal indicator (A1h2) during flashing for special functions comes from the rear SAM control unit with fuse and relay module (N10/2) via the CAN-B. For this purpose the rear SAM control unit with fuse and relay module (N10/2) receives a corresponding message from the special vehicle multifunction control unit (SVMCU [MSS]) (N26/9) via the CAN-B.
Anti-theft alarm system flashing (with code (551a) anti-theft alarm system (ATA))
The signal to actuate the audible turn signal indicator (A1h2) during anti-theft alarm system flashing comes from the front SAM control unit with fuse and relay module (N10/1) via the CAN-B.
