fuel BMW 5 SERIES 2003 E39 Drive Away Protection Syst

EWS
Principle of Operation
When the vehicle is locked from the outside, a High signal is sent to the GM from the door
lock switch. The GM receives this High signal and outputs a High signal to the DME. The
circuit from the GM is spliced into an existing circuit from the BC to the DME.
A High signal from the GM (or BC) causes the DME to cancel the fuel and spark functions
to the engine resulting in a no-start condition. The vehicle must be unlocked with the key
or the code function of the BC cancelled for the DME to allow engine operation.
The status pages of the ZKE and DME will show the condition of the Drive Away
Protection signal as High/Active or Low/Not Active.
