1.14.3.2.1 General description

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2010 BMW X6, 2010 BMW 535xi, 2010 BMW 535i, 2010 BMW 135i, and 2009 BMW X6. However, it is still accessible from the selected car via links, so may be relevant.

The purpose of this diagnosis is to detect an implausible jump discontinuity or implausible gradient or implausible offset on the intake air temperature signal. If a jump discontinuity is located, the error is not de-bounced and is registered in error management. If an implausible gradient or offset is detected, the error is de-bounced.
