Hello all,
I am new on a Forum. Just bought a 2000 H1 wagon, after undercarriage with a powerwash ABS and TT4 light came on. I shorted pin# 4 to pin# 15 and I got code 2-6 on ABS light flasing.
Please anyone advice.
Thank you in advance

Check the tone rings on your half shafts.

 

Thank you 3Hummers for your advice, I had cleaned out tone rings with WD40, but lights still stay on. Would you please give me more details how and what to look for at the tone rings.
Thanks

Please check the above link for ABS modulator repair for ABS and TT4 problem.

 

If you powerwashed them you could have bent them slightly. They are pretty distance sensitive.

 

I just had the same problem today. I had the H1 in the shop to repair some CV joint boots and drove it for one day and I have the same problem and they also repaired the seals were the halfshafts go into the hub. Scanned it and it came up with 4 codes two had nothing to do with it but they are looking at it.

I hope its not expensive. I just spent $5K on the girl.

washed my half shaft rings and after a few minutes of driving the lights when off. Cool she's good as new.

 

I've read different ways to adjust the speed sensor. What is the best way. One guy says a hammer and a credit card for tolerance.

Please let me know.

I bought an ABS modulator of Land Rover Discovery II off ebay for $150.00 Took it apart and replace a shuttle valve on my H1. Code 2-6 and lights are off. Thank you for all of the advise
