S300 power to led lights
I have a s300 in a crx and I’ve looked to see if the d3 light stays on after the key has been switched on. It seems like it’s supposed to but mine goes off after a second I’m just trying to figure out if it’s normal or a socket issue
Re: S300 power to led lights
Ignoring the lights, is it working as it should?

I haven’t been able to connect to the laptop either No upload or data log
Re: S300 power to led lights
What is the serial number that is on the s300 board inside the ECU?
Who installed this s300 and did the socketing of the ECU?

38715 I bought it used I’m not sure who did the socket it worked fine for awhile ever now and again I would have trouble getting it to connect

Post pictures of the bottom of the ECU showing the soldering where the s300 was installed.

Re: S300 power to led lights
Could the wiring harness have anything to do with it

Re: S300 power to led lights
It could be any number of things. I can't really see the solder joints as it is out of focus. Have the capacitors been replaced?

I’m sorry I tried to get it to focus better not that I know if I thought about ordering a kit and putting all new ones in the board has a tiny brown spot next to c14

Re: S300 power to led lights
I would start by replacing the capacitors and see if that resolves the issue, as they are more than 25 years old.

Re: S300 power to led lights
Ok had the ecu completely refurbished with all new capacitors and socket kit and it’s still not connecting to the laptop On the dash it says ignition off I’m thinking a wire problem but I’ve tore it apart and don’t seen anything obvious
Re: S300 power to led lights
Is J12 cut in the ECU?
