Default Re: ABS Issues

Ok. ABS is fixed. Tore apart the plenum to get to the ground. Much easier this time but trashed the gaskets so had to wait for them to get the top end back together. While I waited, I pulled the halo and checked grounds on both driver and passenger side. Both looked new as did the one on top of the bell housing. Checked all the sensors again because I had the time. Check all the ground for the ABS and Ride Control because I was there. Everything was as it should have been. Less than 1 ohm resistance for all ground circuits.

Once the motor was back together I had also received the Tech 1A ABS adapter. Hooked it up and ran the ABS auto test and it passed. Cleared the 32 and 36 codes I had from before and ran it in monitor mode. Right Front had no speed signal. I know the sensor is good because I tested it. So I run it again to show the wife. After the power cycle now both the front sesnors show no speed. Too many wierd symptoms so I replaced the ABS computer with one I bought last weekend that also arrived while I was waiting for gaskets and bam. Passed auto test, no ABS lights, speed signals were all there and the best test I could think of passed - slammed on the brakes and the ABS Active light was bright and pretty and the ABS actually worked.


Figure I still saved money after getting all the tools, spares and Tech1A over taking it in for repair. And I like new tools.
