ABS Lights On

Stick? Are we talking at the wiring connector? I'm sure we'll get there in the end, one way or another.

Connector yes. You can also test the pump with 12v direct from a battery

[TREVCOS]

Id imagine the pump isn't running, it doesn't click just a low frequency general pump noise for a short while ignition is on (could be seized), did you check to full cable to Battery for this, they can break under the sheathing

I'm wondering if I check for the 12v on the connector, if that's okay then it'll be the pump that's seized, if not it could be the wiring?

[ablc]

put a fuse for test with 12 v

I'm wondering if I check for the 12v on the connector, if that's okay then it'll be the pump that's seized, if not it could be the wiring?

Yes, that is a good idea. Have you got a meter to measure volts?

[TREVCOS]

Yes, that is a good idea. Have you got a meter to measure volts?

Yes, got a meter, although whether I'm doing it right, certainly isn't showing 12v though on the plug whivhever way I put the terminals on.

[TREVCOS]

Right then guys, I am doing this right, I've tested the battery and it's showing good voltage about 13.6V I think, if I use the meter on the plug, with ignition on and foot on the pedal it's showing 150mv or thereabouts, when you take your foot off the pedal it's showing just over 200mv? What do we reckon based on those readings?

[ablc]

do you have wiring diagrams ?

[ablc]

have you check here the tree D connector ?

[TREVCOS]

do you have wiring diagrams ?

I've got the big manuals. No, not checked that yet. Is that the only one related to the abs in that block?

[ablc]

the abs light, one wire going to switch pedal and the over go to abs modules

[TREVCOS]

Yep, that one is showing good voltage, in fact I went across all 3 where you have access to the bolt, touched the earth on the battery and the bolt heads with the positive and all showing about 13.6v.

[TREVCOS]

I'm wondering whether to try attaching a battery to the pump with a couple of connectors to prove once and for all if the pump actually works. Any ideas which is the positive side of the plug and which is negative?

[ablc]

the negative seems to be BR= brown anD positive RT= rouge

[TREVCOS]

Thanks mate, I'll have a look at that next. It does feel like there's no power going to the pump from that plug, although I could definitely be wrong.

[ablc]

the stop light working ?
they have tree relays forABS pump but i don't know who they are.
