Outputting acoustic warning messages, function - GF54.30-P-2013A

MODEL 215,

220 as of 1.9.99

Function of acoustic warning:

The acoustic turn signal indicator (A1h2) is integrated in the instrument cluster (A1). This is a contactless relay.

The turn signal flasher is always accompanied by an acoustic clicking sound generated in the same rhythm. The acoustic turn signal/flasher function varies according to the type of signal:

Turn signal flashing:

The trigger signal for the acoustic turn signal function (A1h2) comes the steering column module (N80) via the interior compartment CAN. If one of the turn signals fails, the acoustic turn signal indicator (A1h2) operates at twice the usual frequency. The instrument cluster (A1) receives the information via the interior compartment CAN after the signal is originally generated by the control unit governing operations within the circuit in which the issue arises.

Hazard warning flashing:

The trigger signal for the acoustic turn signal indicator (A1h2) function comes from the upper control panel control unit (N72/1) via the interior compartment CAN.

Anti-theft alarm system flashing:

The trigger signal for the acoustic turn signal indicator (A1h2) function comes from the left front SAM control unit (N10/6) via the interior compartment CAN.

Special functions flashing:

The trigger signal for the acoustic turn signal indicator (A1h2) function comes from the special vehicle multifunction control unit (SVMCU) (N26/9) via the interior compartment CAN.

Warning chime:

The instrument cluster (A1) has a speaker which outputs an acoustic signal (gong or short buzzer tone) in the case of various faults and operating conditions. This acoustic signal is usually output once only. In some cases, however, the signal is output repeatedly.

The gong sounds:

When fault and warning messages of medium and top priority occur (in addition to the message that appears in the multifunction display panel (A1p13)).

When the seat belt warning lamp (A1e9) lights up. This indicator lamp is not available in all country variants. The trigger signal for the lamp comes via the interior compartment CAN from the left front seat adjustment control unit with memory (N32/1) and/or from the right front seat adjustment control unit with memory (N32/2).
The brake fluid level and parking brake warning lamp (A1e7) lights up when the vehicle starts to move before the parking brake is released. The gong sounds until the parking brake is released or the engine is switched off. The trigger signal comes via the interior compartment CAN from the left front SAM control unit (N10/6).
When the ignition key remains in the electronic ignition switch (EIS) control unit (N73) with the ignition off and the door is opened. The "ignition key status information" and the ignition OFF signal come via the interior compartment CAN from the EIS control unit (N73), and the door contact signal comes from the rear SAM control unit (N10/8).
When the standing lamps are on, the ignition key is withdrawn and the driver's door is open (lights warning). The "ignition key status information" comes via the interior compartment CAN from the EIS control unit (N73), the door contact switch signal from the rear SAM control unit (N10/8) and the standing lamp signal from left front SAM control unit (N10/6).
If the child safety lock is unlocked. The trigger signal is transferred from the pneumatic control unit (combined) (A37) to the interior compartment CAN.
When specially protected vehicles exceed a speed of 210 kph. The gong is canceled as soon as the speed drops back below 207 kph. The speed on the electronic speedometer (A1p8) is used.
When the vehicle speed exceeds 120 kph (Gulf states only). The gong is canceled as soon as the speed drops back below 117 kph.
When the speed set at the variable speed limiter is exceeded owing to inertial acceleration (e.g. when driving downhill).
The displayed speed is used. The set maximum speed comes via the engine compartment CAN from the motor electronics control unit (N3/10) or from the CDI control unit (N3/9).
If the selector lever in vehicles with "keyless go" is not set to "P" and one or more doors are open. The selector lever position signal comes from the ETC control unit (N15/3) via the engine compartment CAN. The door contact signal is transferred from the rear SAM control unit (N10/8) to the interior compartment CAN.

The buzzer tone sounds:

When the DTR warning lamp (A1e59) lights up. This lamp is actuated when the distance to the preceding vehicle falls below the defined safety margin. The signal comes via the engine compartment CAN from the DTR control unit (N63/1).
