Function of fanfare horns - GF54.35-P-0001A

MODEL 202 as of 1.6.97, 208 up to 31.7.99, 210.081 /281 up to 30.6.99, 210 as of 1.3.97 up to 30.6.99 

Function 

The fanfare switch (S4/2)  is connected to the electronic ignition switch (EIS) control module (N73)  by the horn/airbag clock spring contact (A45)  .

When the fanfare switch (S4/2) is actuated the corresponding input on the electronic ignition switch (EIS) control module (N73) is connected to ground. If the starter switch is at least in position "1"  , the electronic ignition switch (EIS) control module (N73) transmits a message to actuate the fanfare horns (H2)  to the driver-side signal acquisition and actuation module (SAM) (N10/1)  via the CAN data buses.

The driver-side signal acquisition and actuation module (SAM) (N10/1) actuates the fanfare relay (K40/2k6)  . This relay is located on the driver-side fuse and relay module (K40/2)  . It switches the fanfare horns (H2) to circuit 30 and the horns honk.

NOTE: One lead from the fanfare horns (H2) is always connected to ground so that actuation is always accomplished by connection to circuit 30 (via K40/2k6).

The coil of the fanfare relay (K40/2k6) is permanently connected to circuit 15R so that when the fanfare horns (H2) are actuated the other connection is connected to ground by the driver-side signal acquisition and actuation module (SAM) (N10/1).

Diagnosis 

Diagnosis can be accomplished with the HHT and the diagnosis manual.
