Thread: Smart mechanic

Hi, first of all you should do somehow to get to your friend again and plug in nanocom cos there's a quite big chance to have other fault not SVS related if the wiring mod was made cos i suppose(or at least let's hope) that who made it knew to measure the resistances of the switch pack and also if there was a sign of brake fluid ingress he would have told you... so make sure what fault it is before you spend more money on it cos now it can be a worn hub, an earth issue or something else too


by the way do the amigos reset on ignition or it's permannent, and if they reset can't you see the ABS light alone untill you drive it?...that's important


also if the wiring mod is done you can access the two wires(the one to earth and the other to the yellow/green wire) so if you can handle a multimeter you can check yourself the resistances of the switch pack on those wires, you must get 3Kohm with pedal released and 1Kohm with pedal depressed... if you get these values no need to replace the SV switch pack

Thank you for the answer, tonight I will try with the multimeter...
I try to call up my friend for the nanocom reset...
Anyway I never had only the abs light...

agree with sierrafery's comments

do all the tests so you have all the data first, including checking each wheel sensor. all the info on how to do this can be found in the good oil and a fried with a code reader

$450 to do the shuttle wiring mod - wow - and no replacement of the shuttle valve for that - double wow.

I bought a new shuttle valve kit of ebay for $99 and did it myself in an hour - wasn't too hard, just tight fit and you don't need to undo any of the brake lines etc.

Good luck - this can be frustrating - I was lucky and only had just the one fault code, but i did all the tests on the wheels so eliminated as much as i could before doing the shuttle valve. Problem hasn't returned as yet - just over 4 weeks.

For the test with multimeter you'll have to unsolder the wire which is connected to the yellow/green one to not get any parallel resistance against earth, the other one leave it alone and measure across that wire which was connected to yellow/green and earth...then if the readings are good solder it back, if the mod is well made the yellow/green wire is cut and the side toward the modulator is left ''in te air''.... there are two earth points in front of the airbox make sure it's good contact there

Is this the cable of the mod?

I can't see any other cable underneath...

How can I check if the mod have been done?

I can't figure out anything from that pic, if you reach under the modulator you should feel two wires coming out from the bottom of it(SVS pack) one connected to earth and the other connected to the yellow/green wire in the loom which goes to the modulator's multiplug to the part which is going toward the ECU and the side toward the modulator let free...that's how it should be...and you must measure on the wire from SVS which goes into the yellow/green wire disconnected and earth.

I had a look on Google how the bypass mod should look and I have nothingike that... I'm worried that he did nothing...
what can I do in this case?
I'm going to ask him to show me the cables of the mod (last time he said that they are well hidden). What about if he refuses or can't show me?
What can I do?
