on my 86 RX, it flashes the check engine light. pull the codes and geta code 12, check FSM, doesn't list one. WJM says see if the connectors are still plugged in, check them and they aren't. it doesn't run bad, but it doesn't really seem to run right either. has an accel coil, 8mm sparkplug wires. anybody have any ideas?

I am getting the same code and have not been able to get rid of it. It has something to do with the ignition switch. Will post the exact code tonight.

u think the exact code is starter switch off, i've got it showing onmy vortex as well

Ok from the 1985 FSM.

 

Code 12 is "Starter switch in OFF mode"

See pic for troubleshooting flow chart:

NOTE connector-1 is the red one next to the diagnostic "green connecter under the dash. For XT's I assume the connector would be in the trunk.

 

old post i know, but has anyone really figured out what this code means exacty? my RX is spitting it out from the LED light with the ignition ON. The car starts just fine, lol.
