MODEL 220 

Fig 1: Hazard Warning Lamps Function Diagram

Function sequence 

Function prerequisites:

• Hazard warning flasher switch actuated.

1. The position of the hazard warning flasher switch is read in by the upper control panel control module (N72/1).
2. The upper control panel control module sends a signal (1) to the jacket tube module (N80) via the CAN bus.
3. The jacket tube module generates the flasher message and sends a signal (2) via the CAN bus to the
   • instrument cluster (A1),
   • left front SAM control module (N10/6),
   • right front SAM control module (N10/7),
   • rear SAM control module (N10/8),
   • trailer recognition control module (N28/1),
   • left front door control module (N69/1 and
   • right front door control module (N69/2).
4. The instrument cluster (A1) actuates the audible turn signal indicator (A1h2), the left or right turn signal indicator lamp (A1e1, A1e2).
5. The left front SAM control module (N10/6), right front SAM control module (N10/7) and rear SAM control module (N10/8) actuate the following lamps:
   • left front turn signal lamp (E1e5),
   • right front turn signal lamp (E2e5),
   • left rear turn signal lamp (E3e1)
   • right rear turn signal lamp (E4e1).
6. The left front door control module (N69/1) and right front door control module (N69/2) actuate the following lamps:
   • left exterior mirror turn signal lamp (E6/5) and
   • right exterior mirror turn signal lamp (E6/6).
7. The trailer recognition control module (N28/1) actuates the trailer hitch socket (13-pin, X58), if necessary.

If the jacket tube module fails, the flashing signal for the hazard warning flashers is generated by the upper control panel control module.
