Type E door locks are controlled by an electrically activated vacuum pump; however, this DEI system is not
capable of controlling Type E locks.
This system usually requires a negative pulse to unlock, and cutting the wire to lock the door. In some vehicles,
these are reversed. This system is found in late-model Nissan Sentras, some Nissan 240SX, and Nissan 300ZX 1992
and later. It is also found in some Mazda MPV and some Mitsubishi models.
One relay (optional) is used to interface to this type of system as follows:
type F: one-wire system
type E: mercedes-benz and audi (1985 & newer)
