Factory Central Locking Motors At Rest, Toad RK30, 1998 Mitsubishi L300

So you've measured 12 volts output from the keyless module? Verify it's only output on one wire at a time (lock/unlock). I'd be willing to look at the diagram/manual.My ex once told me I have a perfect face for radio.

I have measured +ve 12 volts at the lock and unlock wires which connect the keyless module to the wires cut from the switch to the motors. The wires you suggested I add from the other side of the switch(which I had previously left unconnected) to the relays(as triggers) stop the whole system working.So I disconnected these which has allowed the keyless entry side to work through relays.The switch no longer works,though. I will endeavour to upload the wiring diagram later Shaun

Unfortunately I seem unable to change the manual/wiring diagrams from PDF format to something acceptable to the forum. Is there another way I can do this?Shaun

Please see Toad RK30 fitting/wiring instructions in the downloads section... I am currently using the first connection diagram, Positive trigger locking. Thanks Shaun

Use the one on the bottom right.My ex once told me I have a perfect face for radio.

Thanks for that. If I use the diagram at the bottom of the wiring diagram It didn't work properly. The only diagram which worked was the positive trigger locking ,but without the switch being connected.(ie the blue/red and grey/red just connected direct to the motor wires). I simply cant find out how to incorporate the factory switch as well. The nearest diagram for this is 4 wire reversal,but this shows the alarm/lock output on pin 85 to be a negative output. Having established that the Toad RK30 gives a positive trigger I really don't know how to do this without blowing loads more fuses.. Your continued advice and support is much appreciatedShaun

I wonder if I caused you to damage something internally when the fuse blew earlier. The bottom right diagram is still the correct diagram. (I would think the positive switching diagram would also work.) You say you tried but it didn't work. Since this unit has built in relays, there should have been no need to add any external relays. We didn't know this initially. Did you connect it between the relays you added and the actuators? I haven't heard of Toad here in the states. Have you verified the functions of the relay wires as listed by Toad (lock C, lock NO, lock NC, etc.)?My ex once told me I have a perfect face for radio.

How have you established that there are inbuilt relays?The only paperwork I have is what I have sent you.As a rule,I tended to fuse with a 10amp fuse to protect the circuits.The fuse fitted inline to the module was 15amp,and this never blew,so hopefully we are OK.I hadn't realised when I purchased the unit that information regarding this unit would be so hard to find.I haven't verified the functions of the relay wires as listed by Toad.I connected the unit before the external relays,using the two output wires lock/unlock from the unit as trigger wires.The external relays are fitted with diodes,to protect the module from flyback.Maybe I will just have to settle for the remote entry,leaving the factory switch disconnected..? Hope this helps.... Toad are part of the Scorpion Automotive group,but maybe I should have bought differently. Shaun

The common (C), normally closed (NC) and normally open (NO) wires identify this unit as having built in relays. A relay is nothing more than a switch controlled by an electromagnet (the coil). On a typical automotive relay, terminal 30 is common, 87a is normally closed, and 87 is normally open. Normally refers to the terminals' positions when the coil is not energized. Knowing this, you can verify your keyless unit's wires. For example: Unenergized, the grey/red wire should have continuity with the grey/yellow wire. When you press the lock button on the remote, these wires should momentarily lose continuity and grey/red should have continuity with red/yellow (again, momentarily). Pressing lock should in no way affect the unlock wires. The same test can be done for unlock. This way you can verify and make any necessary wiring changes due to typos/misprints in the Toad manual. I'm not familiar with Scorpion, but perhaps that's just because I'm on the other side of the pond.My ex once told me I have a perfect face for radio.
