TYPE-D
All vehicles without power door locking and vehicles without door
lock motors are Type-D. The 2310 can interface with Type-D only with the
use of a pair of optional VISION 792H-1C-24 relays and the purchase of op-
tional VISION 316-24 door lock motors. See
Fig-7
below for connections.
TYPE-E
Vehicles which have vacuum pump locking systems are
not sup-
ported by the 2310 at this time.
TYPE-F Vehicles that use a single wire to control door locking are Type-F.
Typically, doors lock by open-circuiting the control wire and unlock by
grounding the control wire. However, some Type-F vehicles do the exact
opposite — ground the control wire to Lock and open-circuit the control
wire to Unlock. Yet other Type-F vehicles use (+)24v instead of ground.
The 2310 can interface with Type-F only with the use of a pair of optional
VISION 792H-1C-24
relays.
MULTIPLEX
Many vehicles now use computer-controlled locking systems
that send varying pulse widths on the control wire, often in conjunction
with resistors. Also known as “multiplex” door locks, the control wire leads
from the lock switch straight to the Body Computer (BCM) or to the fuse
box. You can test for the presence of resistors (typically 250Ω to 7.5kΩ in
size) by cutting the control wire, setting your DMM to measure Ohms, and
measuring the “switch side” of the control wire between ground or (+)24v
while pressing Lock or Unlock.
Multiplex door lock systems are
not sup-
ported by the 2310 at this time.

You can power up to 4 motors in parallel
off two 792H-1C-24 relays. Be sure to feed
the relays with co24v and Ground.
Use 16AWG extension wire for 24v & GND.
