Post by 4doorcivic16 » Sat May 18, 2019 4:14 pm

hey, I recently bout s300 v3 for my b20 vtec set up 98 civic ex. I'm getting a code 15 for ignition output single I have checked and changed distributor, coil, and ignitors 2 to 3 times with known working ones and ignitor is still not signaling coil, also tried s300 in another car same thing but if I put a p30 in the car I get spark. what am I doing wrong here?

code 15 is typically a bad ignition switch. On rare occasions it can be the main relay or the ecu itself.
Test your s300 board in a different known working ecu and see if you still get the same problem. If not, the ecu itself is damaged and needs to be repaired or replaced.

More than likely it is the ECU itself. Try your s300 in a different ECU and see if the problem goes away.
