how do you read the codes on an 89 crx si it has the pm6 ecu. I thought that you had to look through the view window but not sure.

 

just lift up the carpet by the passenger side kick panel and u should see ur ecu...there is a blinking light that displays the codes... long blinks count as 10 while short blinks count as 1...
for instance !.....!.....!.!. is code 22
!.....!.!.! is code 13
make any sense?

 

in my 89 DX it is just constant flashes. 17 flashes is code 17.

 

yeah lift the carpet but also you need a little wire to bypass a blue conector on the passanger side wall under the glove box and then turn the key to on and then the ecu will start blinking

 

so what do i do with the wire do i just put it in there?
thanks

 

im running a pm6 in my hf, and i don't need yo bypass a blue wire?? i have no idea what thats all about. and, be sure to take off the protective cover. don't know if you work on cars or what, so im not being a smartass, but just in case you don't know, the ecu is behind that cover.

 

all u need to do is turn the key to the on position and look at the light...i dont know what he is talking about with the blue wire
