Signal for ignition off time 1)
* Implausible signal /SP
1) If, when the ignition is switched on, no "ignition off time" signal is detected by the operating and display
unit -E87(transmitted by the dash panel insert), the -E87 assumes a standing time of more than 4 hours and it
is assumed that the engine temperature is the same as the ambient temperature. In heating mode, the fresh
air blower may thus have a delayed start despite the engine being warm. Ambient temperature indicator -G106
in the dash panel insert may also display incorrect ambient temperature values.
