That's a very similar experience to what I had at the lexus garage. They gave me the wrong part number, so I was hunting a part that never existed for over a week before I got the screw drivers out and greasy hands and found the parts myself. Within 2 days I had the part fitted.
The independent garage that fitted the ABS actuator was able to clear down the ABS and Desceleration Sensor error codes, just the Yaw Rate sensor code still exists and was not able to be cleared using a computer, hinting that the Yaw Rate sensor is borken
Thank you Tigerfish, I did try that before, although admittedly, not leaving it for 30 seconds, I'll give that a go tonight. I did see a correction in another post that for the RX300 the DLC3 connectors are 4(CG) and 12(TS), not 14(TS). This still didn't fix the issue so think the sensor might be broken.
What I need to know is whether I can fit a Sensor on my car with the part number 89183-48010 Serial number 174500-5233 when the part I took off was 89183-48010 serial number 174500-5232. Part numbers match, serial numbers don't.
Anyone know?
