3 Amigos (again sorry chaps)

gjmac · Sep 9, 2017

Hi all,
Not posted in a while, my apologies if this has been covered before.

First question: why are the three warning lights called "the three Amigos"?

Second and more complex question: I have the lights on and have run the "Lynx" diagnostic. Fault codes showing: 4114 shuttle valve switch failure electrically supervision, current and historical. Live data shows: open circuit (with ignition on) and S/C to ground (with ignition off). Actuator test shows: Shuttle valves failed.

Any help would be very appreciated, clues as to where the truble might be and a possible fix.

Thanks for any forthcoming help.
Take care all,
Mac.

The three lights are known as the "3 amigos" because if there's a fault in the ABS or wheel speed sensors they will all turn up together; where one goes the other two will go too.
Now on to your problem, It could be either the connections inside the ABS modulator to the shuttle valve switch plate or one or both of the shuttle valve switches themselves. The easiest way to test the switch plate will be to remove from the ABS modulator and test it with a multimeter.
If you Google "Disco 2 svs mod" or search here on the forum you should find loads about it.
If you need any further help, PM me.

Thanks for your advice, Brian,
As I've written to you on a personal message, the lights went off on a short drive and have stayed off since! I will however practice doing the modification on a spare modulator to have ready should the lights be seen again.
