Technical Punto Evo GP ABS, ESP And Hill hold light on??

[speedy 500]

Hi,
My Son has a 2011 Evo GP. The abs, hill hold and esp lights have come on and also speedo drops off occasionally? Have changed n/s/f abs sensor as scanner said no signal, lights would not clear. Changed brake pedal switch and all lights appeared to go off. After about half an hour of driving lights have now come back on!! Any ideas would be appreciated???

Check wiring between abs multi plug and wheel sensor for high resistance

Thanks for that, have checked and all appears ok?? Initially there was no reading on n/s/f but replaced sensor and still have same issue. Have also checked abs unit multi plug and totally dry??

Check the integrity of the wiring between the abs multiplug and the ns abs sensor water gets into the plug and wicks up the copper wire rotting it behind the PVC insulation

1. reset the clutch and brake switches:
-untwist from holder
-remove wire connectors
-grab plunger with pliers and pull it out.
-refit.
check if light goes off after a few on/off cycles of the key.

2. get multiecuscan and read the errors.
