ABS Fault Problem

Post by melon118 » Sun Jun 09, 2019 7:59 am

Hi,
Unfortunately, I have problem with ABS, too :/

I think, I have MKI or MKII version, because I don't have diagnostic box

My car doesn't have braking servo, so everything working on ABS pump

One year ago pump stoped working and fault icons ( (ABS) and (!) ) lights up

I try to check fault codes by connect pins in diagnostic port but i didn't see anything on dashboard

Pump is working, I connected it with jumper in relay box and it starts

I tryed to change relays, but still nothing

ABS sensors? Everyone have 1056-1100 ohm's

I don't have any idea what can i do more

i'm start thinking that the ABS control unit is fault, but i don't know how i can check it.

Pleas for yours help

Under this link are photos of my ABS control unit, https://photos.app.goo.gl/98761hYLVYNf9Lvr9

I sense a teves Mk2 unit, which would probably mean a dead accumulator

Look for Jaguar Classic Parts, part number JLM 1907. https://www.jaguarclassicparts.com/uk/part/JLM1907

When ((ABS)) and ((!)) are lighting up at the same time, it is most definitely a faulty accumulator. The scary part: in an ATE MkII system not the inlet vacuum but the accumulator provides pressure for the brake booster. So you are not only losing ABS, but brake boost as well...

Much cheaper replacement

To make sure it fits ask the seller for the size of the thread. It should be metric 13 (M13). Also not sure if this one works with the same range of pressure, but definitely worth asking. I have to buy one. One of these days...

I have bought one yesterday. So let me try it and see if I works. Should be coming from China sometime in July, maybe sooner
