Error code 4051

Davidmac · Dec 15, 2018

Can anybody shed any light on this. I have a 1999 discovery td5. 3 amigos plus the red brake warning light and three chimes come on and stay on when I lose traction. Resets when I turn the ignition off. Hawkeye shows this code.

Fault : 4051 outlet valve right hand front power amp with short to ground

Hi, Jack it up and check the front r/h wheel bearing for play. Mine had worn when these 4 lights came on.
I'm sure more suggestions from others will appear soon.

Thank you Griff. I will check later on when the snow goes off

the explanation is here https://www.landyzone.co.uk/land-rover/unsure-on-this-brake-fault-code.337474/ even though it's about the other side the probem is the same

What I have noticed is that it throws up a fault on the other 3 corners occasionally as well. I see on your post that there is a rewire that can be done using a single wire. Is this an option at this stage or is it an ecu and possibly a new modulator first

sierrafery · Dec 15, 2018

A single wire is an option ONLY if the fault code is the same all the time cos if there are codes for other OVs or IVs each has it's own circuit but as in the other post the modulator and ECU must be ruled out for that

Thank you, I will source a modulator and ECU and see how I get on

start with the modulator cos it's the most suspect
