Bought a used S300 need help
Posted: Wed Mar 17, 2010 9:16 pm
I bought a used S300 for $80 shipped on a car forum. The reason for the price was there was a burnt trace on the S300 board. I figured it was a good deal IF i could get it to work. This is the Seller's story:
His friend was testing some sensors with the car running and grounded out a wire and the car shut off. the seller believes it was the TPS or Map sensor that his friend was testing. the ECU in the car was fried and the car would not start. they removed the S300 and placed it in a working ECU. the car started and they could see the .cal file on the S300 but could not upload to it. that's when they saw the trace was burned. I fixed the burned trace with a with a wire. As you can see in the picture below. the 2 pins highlighted with red dots show continuity. If someone could check for continuity between these points on a working S300 to verify this for me it will be much appreciated. I ordered the s300 install kit from xenocron.com until it arrives I will not be able to test it in an ECU.
