Are the dry joints where the loom plug joins the circuit board or somewhere on the PCB itself?

The orange box is the smart lock module...

The black box beside the cd player is the BEM...

I know this because smartlock "immobilises" the car and thats the orange (red) module... When I was playing around with my variable wipers you'd assume the intermittent timing is controlled by the BEM yes? Well when I unplug the black box the wipers loose their Int function...

Now I fixed my smartlock module and its not dry contacts at all... well not in my case... unless someone else has fixed dry contacts?

There is about 4 or 5 relays on the board... The one that immobilises the car is a relay that is two relays in one (not sure what the other half does)... But its two coils, and two sets of SPDT contacts.

All i did to fix it was unsolder it and turn it around (180 degrees) and solder it back in virtually swapping the relays in the two circuits over... (whatever the other one is?) and I've never had a problem with it since...

My opinion of it is that the relay was not rated high enough of was of a sub-standard quality... and as such causes these problems... I wanted to swap the relays for solid state relays of a higher current capability... This was you have no mechanical moving parts and they last forever due to no mechanical wear...

I'll get around to this one day when I have a spare 30 or 40 bucks to do it as solid state relays aren't cheap and you require two to do the job... and feel like screaming and arguing at the smartlock module when it wont come out from around the hand brake...

Hope this provides some insight... But like I said the two I had here weren't dry joints but d**k relays... Either with gunk in the contacts and they don't close or just plain simple mechanism wear and they wont engage...

Cheers...

Do you know if the relay can be bought as a spare part from Jaycar or DSE?

it's either red with blue trace or blue with red trace. not both those colours are there. only 1 of the combination is there so it'll be easy to find

Cool, now it makes sense. I gather it has an input and an output plug, this is for a friend. Both my cars are pre dumb lock.

so is mine. now don't remove the wires from the BCM. just bare them back and solder a joining wire. tape up and your done. no more problems

Hi there...

No I very much doubt so... It is a very odd relay in terms of the arrangement of the pins on the bottom... I would basically use a dab of hot glue to hold a replacement relay to the board and run little flyleads to the tracks... There really isn't any other way to do it...

Only turn the relay around like I did but its not a guaranteed fix, still just seems to be a s**t relay...

PART EDIT

I would bridge it out but with the number of car thieves these days the more security in it the better so I'm not about to do bridging things out just in case, smartlock isn't a perfect system but it's better than nothing...


it doesn't bypass the smartlock. it's only bridging 2 of like 20 wires
