1) This "signal" comes from the control module within the instrument cluster (-J285-). The<br />

control module -J255- uses this signal after the engine was switched off and restarted<br />

within 2 hours, to replace the values of the current outside air temperature sensor -G17-<br />

and fresh air intake duct temperature sensor -G89- with the last operating temperature<br />

values. The measured values would otherwise be influenced by the radiated heat from<br />

the stopped (stationary) engine. The ignition off signal only occurs after starting the<br />

engine.<br />
