Code P1515 BMW Description

The engine off time is calculated using a relative time counter obtained from the instrumentation via Controller Area Network (CAN) message.

An error is detected when engine off time is adjudged too small after a relatively large drop in ECT, or, conversely, when engine off time is too large after a small drop in ECT.
