Default No front signals

Hey all, i have a 2001 z06. Just had a buddy replace the radiator for me and now i have no front signals at all. I'm trying to get in touch with my friend now to see whats going on but though i'd fish around for some input here too. Any help would be greatly appreciated!
Its the front only...getting fast blinker on dash. No running light either.
Thanks,
Troy

fast blinker is one bulb out so check for broken/burned out bulb

if you turn the lights on and pop the hood can you see any lights laying in there loose??

Only way to know is get the front of the car up in the air and start looking.............
My first thought was bulbs but is it typical for both to go simultaneously?

no but there is a harness that plugs in and it is likely unplugged...if I recall correctly the plug is near the EBCM...

ok...there is what looks like a 2 prong plug with a blue clip that he didnt plug in. Could that be it? Its coming off a line up near the top of the fans near the intake.
I had my reservations about letting this guy do this but i didn't have a lot of money to spare and was trying to do it on the cheap. Its my daily driver so i couldn't have it down for long. Shot myself in the damn foot. I have RA so its hard for me to do tjis kind of stuff myself.

That is the plug for the under hood light and has nothing to do with the lights you described out in the first post...

Not sure it'll reach down to the ECBM but i'll start poking around down there tomorrow unless someone can give a concrete answer as to whe re it might be. I know the brake midule is just below there so i'm hopefull. Do you think i'll need to go from the bottom or from the hood? This is what i get for trying to cut corners with my baby...lesson learned. 😕

That looks like the Magnasteer connector, to me.

cool...i'll give that a shot in a few. Might be a stupid question but if i pull the neg batt cable to clear DIC then start car, will the new code pop up right away? I know i have some ongoing TCS, AND DOOR CONTROL codes in there that are ongoing. I get active handling errors as soon as i turn the wheel on start up. ( thats the next project.)
Also, if by chance that lead does have something to do with front lights would that throw a code?
Thanks to everyone for helping out this noobie. I do appreciate it.

Ok guys...here what the DIC gave me:
*C1241
C1283
C1286
C1287
C1288
*C1293
*B0502
*B0507
*B2482
As i mentioned...there were a few that were already there. I just ran it the other day before the radiator repair so i've marked the new ones with an asterisk. So as 8VETTE7 thought it looks like the magnasteer that is the issue for the loose clip. I just can't see anywhere the damn thing plugs in for the life of me.
checked fuses for everything that looked light related and they all look good so i'm still at square one one the flasher problem.
thanks, Troy

The other end of the Magnasteer connector should be clipped onto one of the power steering cooler lines.

SOLVED: It was both bulbs. Found the socket for the steering and all is good. Now i just need to deal with active handling and all is good....then again...what fun is traction control! Ha!
thanks to everyone for the input and help!

Is that pretty much a dealer only fix? As I said I can't really do work myself - no cartilage in my wrists from RA. Would you trust it to someplace like a firestone? I hate the thought of getting gouged at the dealer.
Thanks!

The part # for the SWPS is 88965543. They cost about $70 and take about 2.5 to 3 hours to replace. Since your car is an '01 they can still be bought new.

I personally would NOT trust it to a shop like Firestone. The steering wheel cannot be turned while the column is out or you damage the clock spring. If you have any Corvette repair shops in your area talk to them. Most likely will be a little less expensive than the Stealership as usually their labor rates are less. As with many repairs labor is a big cost.
couple hours isnt too bad...and you're pretty sure it has nothing to do with the ECBM? Someone here was discussing that when i searched for these codes a while back.
I really appreciate the input! I've been putting it off for a while now. It used to be intermittent but now it pops up as soon as i turn the wheel backing out of the garage in the AM

A Vette shop has likely done this repair many times (common problem) so they should be able to qoute you a fair price. Some stealerships don't know squat about the C5 and using Firestone is just asking for trouble.

To pull codes with the engine running you need to use the RESET button to clear all messages from the DIC. Then pull and post ALL the codes that have returned. Include the H or C or HC that follow each 5 character code. List the codes with the sensor that they are reported under. ie 10 - PCM or 28 - TCS or 40 - BCM.......... etc .......

If any sensor reports NO COMM include that information as well.

We will review each code that comes back and suggest the appropriate action.
Thanks a million! I'll try and get on it tomorrow and report my findings then.
You've been a great help!

Ok, here's what I got this AM.
Before work, I reset all codes in the DIC.
Started the car and drove it into work.
Once I arrived I ran the Diagnostic with the engine still running and here's what I got. (Only two codes came up but I'm listing everything just in case.)

10-PCM NO CODES
28-TCS C1287 H C
C1288 H C

40-BCM NO CODES
58-SDM NO CODES
60-IPC NO CODES
80-RADIO NO COMM. (AFTER MARKET STEREO?)
99-HVAC NO CODES
A0-LDCM NO CODES
A1-RDCM NO CODES
A6-SCM NO CODES
B0-RFA NO CODES

Thanks again!
Troy
