Clearing a SLABS ECU fault

[LSUDenver]

My 2000 DII squeaked in reverse this week throwing an ABS fault. I can not get the error in my OBD scanner, so I suppose that it is a BCU fault and I need to have something that will connect to the BCU...?

Yes, I have searched and seen the 3 Amigos issues and fixes. I just want to clear the fault.

Any ideas on a tool to do this or is the only way to go to a LR service shop?

Shop w/ testbook. rovacomm, or autologic. It will be cheaper if you go to an independent shop.

Are you aware of the paperclip in the OBD II connector trick ? If you do a search I'm pretty sure you'll find something in the forums about the procedure also working for D2s, but you might have to short different pins on your OBD connector (?). It seems the resident ABS guru is Chris St. Louis. He's the one that posted the ABS TSB in the first place.
Check out the link below which includes a link to the TSB with the procedure, as well as a link to the .pdf document with the ABS blink codes.
I'm trying to clear an ABS sensor gap fault on my D1 at the moment so I've had to do the search myself

KevLar, that's for DI and some RRC only.
DII = Totally different animal.

Okely Dokely... I stand corrected
Thanks
So does that mean that an ABS fault on the DII means an automatic trip to the garage, or spending hundreds and hundreds on an OBD II scanner that can handle chassis codes ?
Ouch !

Pretty much. The SLABS ECU is specific to LR as far as I know.
Do you have a DII KevLar?

Indy Shop in Denver Cleared it up for me!

Right-O Guys!

I figured this out by getting a basica OBD II scanner and it didn't do squat!

I went by my local Indy shop (JC's Rover 4x4) and Jeff cleared it up for me. NOt only did he do so at a reasonable cost. He is a GREAT guy that loves to tell you whatever you want to know about what is going on with the car.

Jeff Corwin is the MAN in Roverland!

Nope, I have a '96 D1. I've been trying to reset my ABS light with the paperclip method so that's why I mentioned it.

I found out that way too Luckily the D1 ABS light is easy to reset... Well, in theory anyway. My light is still on so either my ABS sensor is bad, or I'm retarded

There is so much that can cause ABS problems that to even try to diagnose it without the correct tools is folly.

When I finally got around to my tres hombres ('00 D2) it ended up not even being an ABS fault - "duty cycle for SLS out of limits".

They wanted (and they being the stealership as I've yet to find an indie guy in the tidewater area) $750 for rear brakes as they said it was the prob.... yeah, right.

The best they could do was clear the faults (6 of em) and when it came on they'd read it again to see what the issue would be... but if I didn't get my brakes done with them, I'd have to pay another $175 to Phillips Land Rover to read the codes again because they couldn't figure it the first time!

Time to buy a big bumper and pull some bulbs... :banghead:

 

[ptschram]

The duty cycle thing was probably due to a known issue desensitizing the system. Tell your dealer there should be a TSB for this problem.

It might even be listed on the list of TSBs that Chris so kindly provided.

Correct tool in this case would be ~ 1/2 lb of Semtex

The latest in my attempts to figure out the ABS light is that I checked the resistance for both rear sensors today. My multimeter is a little sketchy at times, but with the test leads shorted I got 0 Ohms, so it looked like it was working. I got the same reading for both rear sensors (about 1.1 K Ohms) and that falls within the prescribed resistance range (the ABS procedure in the TSBs says that the resistance should be between 700 and 2K Ohms).

The fact that both sensors have the same resistance indicates to me that the one that is giving me problems (Code 2-13 = Left Rear) is probably working (?). I didn't have time to do the voltage check with the wheel spinning at 1 RPM.

So after reseating the sensor a few days ago (I'm pretty sure it's seated properly, but maybe I need to drive it in a little harder since I was pretty gentle with it the first try), and checking resistance, what else could be the problem ?? The ABS light came on during a camping trip on a gravel road. Based on feedback I got in the forum I assumed the problem would most likely be a sensor gap, but now I am at a loss as to what else to check.

Any ideas ?
