in a 2002 car. Someone told me you pull 2 fuses out and turn the ignition on or somthing for 5 minutes. I need to reset my PCM to get rid of my PO757 code for a few minutes to see if things operate normally before the code comes back (getting code deleted today and want to make sure its the computer). Help please

pcm bat and pcm ign fuses are the ones to pull for about 5 minutes or so

Maybe this helps:

Resetting your C5 Corvette's PCM

The procedure below sets your car's PCM back to it's default fuel trim and timing settings, and sets WOT enrichment back to the high octane table if your car has dropped into the low octane table.....

1) Turn key on (leave engine off)
2) Pull fuses #16 and #23 from the fuse box in front of the battery
3) Turn key off
4) Put fuses back

The car will be defaulted back to it's initial startup, idle, part throttle cruise, and WOT fuel and timing settings

PCM Reset
Turn key on, don't start car
Pull PCM BATT and PCM IGN fuses in engine compartment
Wait 5-10 min
Turn ignition off
Replace fuses

Another way is to unhook both battery cables and touch them together, this should clear settings.

I tried this...

I turned the key to the on position.
I pulled the PCM BATT fuse...but then I noticed some smoke coming from inside the car's dash.

I immediately turn the key back and took it out. I then took off the radio dash trim...I thought that perhaps my radio fried.

(I noticed that the left signal light stayed turned on but it wasn't blinking.)

After I took off the trim piece I saw FLAMES coming from the back!!! I blew out all the flames and ran to get a fire extinguisher. I get back to the car and the flames were out.

I took out the radio and I saw where the flames where coming from...DRL box?







Well, I noticed all the right side of the wire covers had melted together and the left side wire covers were starting to melt.
I seperated the wires so no contact could be made and I tried to start the car...the car started really rough and again the left signal light stayed turned on but it wasn't blinking.

I then disconnected the battery and proceeded to try to "fix" the problem.
I cut off the melted wires and extended the wires to reach out out of the dash. (you can see that there is tape around the wires)








I hooked up the battery, crossed my fingers and prayed that this solved the problem.

I put the key in and tried to turn the car on...NOTHING HAPPENED...
the lights work, the wipers work, the hazard lights work, the RIGHT signal light works, pretty much everything but the LEFT signal light (it just stays stuck on).

I'm scared that maybe I fried my PCM or something...SOMEONE PLEASE HELP ME OUT.
