ABS Warning Code

[mike H]

While my XM was having it's 4 Suspension Spheres replaced at my local garage.I got them to look at why the ABS warning light would not go out. They plugged into the ECU and came up with a code no.195 Security Relay. As they are not sure about this code as they say it normally has a letter in front of the numbers.
Are they right and where is this Relay and is it something I can do myself.

Hi Mike

Watch the ABS light when you switch the ignition on.
It should go through a blink sequence then go out.
Need to know if the light just comes straight on without blinking.
This process is the ECU checking the components.
A relay or power supply fault will not blink.
The binking tells us how far the ECU got with system testing.
I do not recognise the fault codes your garage listed.
Did they use a Lexia or a generic tester.
Might be worth putting a Lexia on if that has not been done.
A Lexia may be able to clear the fault codes recorded in the ECU.

Hi John

Just switched on the ignition and the ABS light just stayed on,it did not blink.

I then started the car the light stayed on along with the message "ABS not in use"
I think that is what it said as this display is abit broken up.

I took the car for a drive,the light and message stayed on all the time.

I do not know what the garage used, but will talk to them tomorrow and report back with any info.

Thanks John for you help.

Hi Mike,
there is a green relay next to fusebox in the engine compartment - you should check it for any rust or damage. There should be +12V permanent on the socket (trough fuse No3 - fusebox behind it)=pin No3(i cant read it ), +12V when ignition is on (trough fuse No1 in the passenger compartment)=pin No4 - you might check them as well.

Thanks Sharo for this info will take alook.

Hi Guys,

John my garage used a Snap-on Solus to check my car out and he said that the 195 fault code he thinks is a dealer code of some sort !!

Sharo the relays all look OK along with the fuses, but I have not checked the voltage yet,but did give them a clean up just in case. No luck yet.
Still have the ABS fault.

Regards Mike

Hi Mike

I had this problem some time ago and it was due to a wire corroding and falling off under the engine compartment fuse box, it provided the supply the the hydraulic block.

Thanks Peter will take alook, lets hope it could be only that.

Not sure about the later cars, but Series 1 XMs have a relay on the ABS valve block, which developed a fault on one of my cars. Regards, Matthew T.

The S2 has one as well Mathew, in fact that is what I thought the problem with mine was until I found it had no voltage on it
