I am using LT1 edit and used free scan to read Code 11 off the PCM. I am not sure why its throwing this code because the bulb for the SES like is good inf act it stays on. What could be causing this.

By the way the a 95 z28 LT1 in a 88 s10 blazer.

 

i got the same code in my 69 chevelle (lt1 m6)
--------------------------------------------------------------------------------
code 11 which is a malfunctioning indicator light
fans will come on at start up

fix
i install a small led indicator light for DTCs
i can't remember which pin

 

That would help me ALOT if you could find out which PIN or wire I need to run a LED off of to fix this.

Thanks,
Howard

 

check blue D9

 

I checked Blue plug pin 9. It is cut and leading to nothing. Can I run it to the SES light in my dash also? Will that stop the problem?

 

I run it to the SES light in dash from (blue )pin 9
it work for me

 

Wouldn't know what other PIN outs could cause would ya? I tried jumping that wire into my SES light on the dash and nothing. I reset the codes but it comes back on and brings the fans on.

 

Never mind. You were right. Some how had it wired wrong leaving the cluster. Just ran another wire to D9 from SES cluster feed. Works!! Thanks a million :-)

 

glad to be helpful

i had the same problem on my 69 chevelle lt1 m6
