GF54.30-P-3002A Indicator and Warning Signals Triggered Over Direct Lines, Function

Indicator and warning signals

Indicator lamps for left turn signal (A1e1) and right turn signal (A1e2)
The signal in models 129, 140, 170, 202 comes from the combination relay (turn signals with trailer coupling, rear window defroster, wiper motor, anti-theft alarm system) (N10/2), and in model 210 from the multifunction control module (N10-1) or the driver's side signal acquisition and actuation module (SAM) (N10/1).
In model 168 the entire turn signal control is located in the instrument cluster (A1).

Brake fluid / parking brake warning lamp (A1e7)
The signal for the brake fluid comes direct from the brake fluid level switch (S11) (except model 163).
(The signal for the parking brake comes over CAN.)

Fuel reserve warning lamp (A1e4)
When the reserve fuel level is reached, this lamp lights up and goes out again only after refueling is detected. If the vehicle is refueled with the ignition ON, refueling is detected only if at least 7 liters of fuel are added.

AIRBAG OFF indicator lamp (A1e56), only model 163 except (USA)
The signal comes from the emergency tensioning retractor (ETR) control module with airbag (AB, N2/2)

Seatbelt/backrest lock warning lamp (A1e9)
The seat belt warning lamp is only used in a few national versions, and is actuated direct by a seat belt buckle switch (normally closed contact). After engine start, the lamp flashes for a short time (approx. 6 seconds).
In model 129 if this lamp fails to go out after flashing briefly, but continues to shine constantly, then the seat backrest is not locked.

Exterior lamp failure indicator lamp (A1e14)
The signal comes from the lamp failure monitor

Hydraulic fluid level warning lamp (A1e37)
