Announcement Of Terminal 15 "on"

For safety reasons certain control units and sensors are not only informed via the bus signal about terminal 15, but also have a direct hardwired output from the CAS.

The CAS provides ten KL 15 outputs for hardwire redundancies:

• Ignition coil relay: the output for the ignition coil relay is equipped with an overrun for maintaining OBD-relevant emission values (Emissions optimization). When KL15 is switched "off" the ignition coils are not switched off until after a run-on time so that any fuel still injected is burned.
• GRS (Rotation/transverse acceleration rate sensor for DSC)
• LM/BLS (Lamp Module, brake-light switch)
• SBSR (Satellite B-pillar right, fuel pump)
• SZL (Steering Column Switching Center, selector lever transmission)
• OBD socket KL15 supply (On-Board Diagnosis)
• Rear seat heating (has no bus line)
• Three are reserved for future use
