Socal3, where in Southern California are you? If you were in the north county area I would say come by the shop...not sure the boss would be happy but would want to take a look maybe after hours.

 

Looking at the errors you are seeing, it looks like there is a communication issue with the "skid control" ECU. It lives underneath the HVAC fan just above the passenger's feet. The U0100 error is telling you there is a comm issue, and the rest of the codes are telling you the skid control ECU is not passing data to the ECM/TCU. That really pisses off the ECM and TCU because it gets speed information from that computer. Have you done anything recently to the system - installed something electrical, done something in the passenger's footwell, or any other mods or changes? This is a very rare type of malfunction, and troubleshooting it might be a real PITA. If it is a bad connection on a connector, possibly intermittent, it could take some very methodical troubleshooting to find it, or you'll spend stupid money replacing ECUs and wiring harnesses to alleviate the problem. I had a similar issue on my Supra when it was about 13 years old, and it took me four hours to find one bad petal on one connector pin to the ECM. Luckily, the pins on these connectors can all be pushed out of the connector blocks and examined for damage. Individual pins can also be replaced if they are sufficiently damaged that they will never work again.

 

Yeah just went out and started the car the engine light does come on and turn off like its supposed to. What I do find odd is that the gear selector is blank in the beginning then goes back to showing P after about 20 seconds.Also how do you calibrate the yaw sensor?

I find it weird that it talks to the car sometimes a few months ago I changed all the door lock settings and it read everything fine. The cable works on a few other Lexus that we have in our family, but I will look into the cable thanks for the input.

I'm located in West Palmdale, but have a place in Redondo that I go to a lot. I would love to meet up with a fellow CL member who is knowledgable in this issue or anything would ratter pay them to help than take the car to the dealership! I also am funny and can bring beer lol.

 

the car is stock except exhaust I put on a year ago. I will check the ecm under the passenger seat. I love this car I really hope this doesn't turn into a money pit problem. It is only a two owner Southern California car with 68k and no accident history

 

what shop are you talking about I'm on Workmans comp for a few more weeks so time is on my side

 

The skid control ECM in the '08 isn't under the seat. It's under the HVAC fan. You have to remove the passenger's kick panel to see it. If you haven't messed with any of this stuff, the failure is likely a factory defect.

 

Thank you for letting me know the location I am a second owner so I will take a look at the ecm. Thanks again
