9 Inhibit Circuit Relay #2 Open Contact
The onboard, 30 Amp, inhibit circuit relays are capable of interrupting any circuit that will prevent the vehicle from
running. These circuits include, Starter, Ignition, or Electric Fuel Pump.
To interrupt these devices:
1 Locate the low current feed wires for any two of these circuits.
2 At a convenient location cut the feed wire of one of the chosen inhibit circuits, ( Low current starter, Ignition
supply, or Electric Fuel Pump supply), and route the pair of wires 6&7 from the control module to the cut wires.
3 Connect wire # 6 to the key side of the cut wire.
4 Connect wire # 7 to the device side of the cut wire.
5 At a convenient location cut the feed wire of the remaining chosen inhibit circuit, and route the pair of wires
8 & 9 from the control module to the cut wires.
6 Connect wire # 8 to the device side of the cut wire.
7 Connect wire # 9 to the key side of the cut wire.
NOTE: It is imperative that the above connections are secure as they will prevent proper operation if they become
loose or disconnected. If using butt connectors, pull on the connections to insure their integrity. If
splicing these connections, it is best to solder and then tape the joints to be certain that they are secure.
Final Connections:
Route the two pin plugs from the Exciter Coil, LED, and Override/Valet Switch to the control module and plug
each into the mating connector on the control module. Now, connect wire #1 to a constant + 12 Volt source.
Programming Dealer Or Customer Transponders:
First Time Power Up:
When the IMO-720 is first powered up it will be in the armed mode. The unit was shipped from the factory with
a DLM-1 being the last transponder programmed.
NOTE:Before beginning the program sequence, have available the proper (DLM), “Dealer Group MasterTransponder” to
insure proper coding for the particular dealership.
If the unit is being programmed for the consumer transponders have all the consumer transponders available as
these will be used during step 7 below.
Once you’ve entered the program mode, all transponder codes that were previously stored will be erased. Only
the Dealer Group Transponders, (DLM & DLU), or the consumer transponders programmed during the pro-
gramming sequence will operate the unit.
The DLU transponder does not have to be programmed as programming the DLM will allow operation from the DLU
within that group.
NOTE:It is important that no transponder is within range of the Exciter Coil until instructed to do so.
Start with The System Armed all doors closed, and the ignition switch off:
1 Open the vehicle door and turn the ignition switch to the “on” position.
2 Within 10 seconds press and release the Valet/Override push-button switch one time.
3 Within 10 seconds turn ignition switch “off then on”.
4 Within 10 seconds press the Valet/Override push-button one time.
5 Turn the ignition switch “off then on” (The LED Turns Off)
6 Within 5 seconds, begin to cycle the ignition switch “off”, then “on” 3 times. (LED Turns On)
7 Within 10 seconds of the LED turning on, hold the to be programmed Dealer Master (DLM) transponder, or
consumer transponder within range of the exciter coil until the LED flashes one time and then turns off. (If
programming consumers transponders, introduce the second transponder to the coil) LED Flashes two times.
8 Turn the ignition switch off.
The unit will now respond to the Dealer Master transponder and any Dealer Salespersons transponder within the
group of the just programmed transponder, or the consumer transponders if so programmed.
NOTE: The program mode will terminate if the ignition switch is turned off for more then 5 seconds or if 15
seconds of inactivity expire during any of the steps above.
It is important that the door open sequence in the first step of programming be used or the unit
will not enter the program mode.
