Transmitted/measured status, voltage at terminal "15", "75" and "30" 

Display field Meaning Remarks
1 Information transmitted by Steering Column Electronic Systems Control Module J527 to terminal "15"
  • Display = "On"
  • Terminal "15" ON information being applied (ignition switched on)
  • Display = "Off"
  • Terminal "15" ON information not being applied (ignition switched off)
  • Data are transmitted via the CAN-Bus comfort system
  • The Steering Column Electronic Systems Control Module J527 transmits the information "Ignition switched on"
2 Information transmitted by Steering Column Electronic Systems Control Module J527 to terminal "75"
  • Display = "On"
  • Terminal "75" ON information being applied (ignition switched on)
  • Display = "Off"
  • Terminal "75" ON information not being applied (ignition switched off or engine in the process of being started)

Display field Meaning Remarks
3 Application of voltage from terminal "75" at operating and display module, Climatronic Control Module J255
  • Display = "On"
  • Connector "C", contact "13" supplied with voltage from terminal "75" (ignition switched on)
  • Display = "Off"
  • Connector "C", contact "13" not supplied with voltage from terminal "75" (ignition switched off or engine in the process of being started)
  • The voltage is determined via the input from connector "C", contact "13" to the operating and display module, Climatronic Control Module J255
  • With the ignition switched on, voltage must always be applied to terminal "75" except on starting the engine.
