I bought a new to me 22k miles C6 Vert on 6/6. I had to run the key fob in the glove compartment to operate while the replacement DIC arrived at my dealer. This is in no way an attempt to slam the Dealer! (They are allowing me to drive an 08 LS3 that shifts better, has better tires (Michelin), auto top, custom wheels, etc. This is not standard for them - we did not think it would be a big deal to switch the DIC. In addition - I kinda tease about the bad DIC - but I really know 'nothing' about it - so any information posted to the thread about the DIC will be appreciated.)

In general, most electronics worked but tire sensors and key fob had to be inserted (only one fob worked)

After DIC arrival - I rushed the car back for service. Dealer suggested it is about a $500 part. (????????)

After attempting to switch out the Certified Long Term (35+years) Dealership determined that DIC was defective and the car is not hitting a lick 'now' / is sitting dead in their service dept. (I'm SAD!)

They tell me DIC's for 05-0x are on National Back Order. Anyone agree? A replacement should arrive any day! Then it is back to programming. They also tell me the old Key Fobs will need to be replaced to function with the new DIC. All or anyone agree?

I'd really like to have my car back! Lot's of parts are arriving daily and I want to install them and drive it to Bloomington next week for fun.

Echo - This is in no way an attempt to slam the Dealer! I do not have a "Service Manual" nor any real info about the DIC at this time. Any and all feedback and comments will be appreciated.

I did perform a slight search to see different problems associated with faulty DIC's (please be easy with the jokes?)

OMT - I may buy a new set of wheels and sensors (and tires / GULP) - will the new sensors synch with the new DIC or will additional programming have to be performed??????????? Thanks in advance!

 

What messages are you seeing, if any? Is the DIC responding to the buttons at all? Have they put a tech 2 on the car and read all of the codes and if so, what are they? Its sort of sounding like a low battery as these cars really need the power to get going and for the computers to run properly. Since its dead now, wondering if they connected a jump battery to it and see if things take off and go? The fobs are probably not programmed properly to the car or the car has lost its memory in the RFA which is why you are having to put the fob in the slot. Check all of the fuses.

 

It's a new to me purchase. I have not seen the codes as of yet! Yes, it has a new(er) battery so the existing codes could be (all) generally bogus.

The auto is at a Long Term Successful St Louis Dealership - they may take it upon themselves to wipe the codes before I see them. Who knows? I guess, it's complicated. I bought it from an Independent Dealer who is using an Authorized GM Dealer for 'THIS' Service. My independent says he has the previous codes after their purchase (I'm trying to get those too! Am now focused on current and going forward though.)

Now auto is dead; doing nuttin honey! When I last drove it.... it was responding seemingly all fuel calc's, distance estimates and fluid temps. Echo - no tire pressure data / fob had to be inserted in glove box holster. I think door locks were peculiar - but am NEWBE.... so no needs there....

Tech 2 - Is that mostly a Dealer ($$$$$) Product for these outputs? I am trying to acquire the current codes (been searching here for more info and finding some!) I will be trying to use independents - reading devices to get this sorted OR purchase a economical reader for personal (or club use?)

I have NO Idea if the vert was ever jumped. Echo - batt is now new. When I see AUTO AGAIN - I will be happy to check the fuses!

TY Very Much for FEEDBACK!!!!!!!!!!!!!!!!!!!!!!!!! Happy Father's Day if applicable or not!!!!

 

You might want to get under it to the starter as well and see if the connections there are clean and tight. You can get a CAN code reader yourself and run codes but they generally only read the PCM/ECU codes and not the other systems. Have them jump the thing and see if it comes to life.

 

I saw the comment about the starter and sprucing the connections; thanks for reminding me! I'll add that to my todo list. THANK YOU for additional feedback.

Holding my breath to pick the beauty back up tomorrow PM.

 

I could have died from holding my breath. Car was NOT READY Today. (cusswords and stress!)

ECHO Question / need response please - OMT - I may buy a new set of wheels and sensors (and tires / GULP) - will the new sensors synch with the new DIC by themselves or will additional programming have to be performed??????????? Thanks in advance!

 

TPMS are programmed to the car using a special tool.

Most tire stores installing your new tires will do this 5-minute job for free. You can transfer your old ones to the new wheels if you want.

Fobs need to be programmed to the car as well. Up to 4 can be programmed but only fobs #1 and #2 will have the driver preferences coded to them. If you use a #3 or #4 fob, you select the preference using the switch on the door.

A fob with a dead battery in it will still work for starting the car if it's inserted in the glove box slot.

C6's are prone to all sorts of battery-related glitches. Once you have a new battery keep it topped up with a battery tender.

These are relatively cheap, easy to connect if you use the adapter and plug it into the lighter socket (it's always on) and should be used anytime the car is going to sit for more than 2 weeks.

Sorry for your troubles. The types of gremlins you are dealing with can be a quagmire to troubleshoot. Hopefully you have a dealer with a qualified and persistent master mechanic.

Good Luck, keep us posted on your progress.

 

THANK YOU FOR FEEDBACK! I'll have another question below. First a perspective..

I have four Motorcycles and a John Deere Lawn tractor that have quick disconnects on them (bikes include adapted by me harnesses for Electric Gerbing Clothing) AND either Battery Tenders or similar Yuasa - tenders on them full time. Your advice will be utilized asap or as needed. I'm gonna drive the car 'frequently' for a while too!!!!! I have a truck (for building stuff and hauling motorcycles/ and I've worked from home for years - so gas mileage was not a problem for me per sae) been away from nice cars for TOO LONG! Wife has a 'very' nice car I drive (used to drive?) on occasion! My OH....6 is a incredible treat now though! TY!

Maybe I will get my Black Beauty Back today???????????? (Good Grief!) I have so many parts to put on it! Life is GOOD!

Thanks for feedback about 5 minute job for programming and talent can be had at local tire performance centers!

New Question: I'm likely going full bore with new Michelin Tires (Summer) and will keep my Chrome Gumby's and Firestones for winter months / desperation driving. Can / Will both the NEW programmed sensors and OLD sensors be read by the DIC Module while installed? Or is it one or the other????????????? (more likely)

"Heresay follows - It appears Michelin has pulled their Runflats (ZP) in the Pilot Sport PS2. Some providers still have them in stock / some do not. In addition, it appears Mich will be releasing a new version of their ZP Sport Tires called the 'Pilot Super Sport' in the 'near future' (unknown timeline to me at present / doing research!) and they will be the 'only?' Manufacturer to offer a Mileage gaurentee of a minimum of 30,000 miles (prorated - but I have no other details at present.)

I think I will be buying wheels next week.

Future feedback sought (I'll use search engine here too) will be if I want to run ZP's or adapt a emergency use kit for plugs and inflation needs. I've heard ZP's are more noisy - but the tire tests I have read on Mich allow them to stand tall on their own for Noise and other factors. I'm sure there won't be any test data on the speculated new Pilot Super Sport by the time I will want to execute the tire purchase. Not much of a problem to have...... (Paying for them will be though; lol) If anyone knows of a poll or great threads about zp's vs non zp's please send a link.

THANKS FOR FEEDBACK and sure I'll be glad to keep interested folks informed. This auto will be worth the wait when I post pic's... (keeping in mind it's just an 06 z51 vert)

 

You can only have one set of TPMS programmed to your car at a time.

That doesn't mean you can't drive it with un-programmed sensors. The car takes about an hour or so before it recognizes that the sensors are 'wrong' and then it will intervene, mildly (check your Owner's manual for more detail). But you can still drive it, like getting to the tire shop for programming/etc.

If you are going to be changing wheels/tires frequently, invest in the programming tool, it's around $125-150 as I recall.

As far as your choice of Michelin tires go, it's a good one. I have PS ZP's (not PS2's) and they are quieter than the OEM GY's.

Can't really comment on the performance of the tires you have in mind, but one thing seems to be universal with Michelin 'summer' tires, they don't like cold weather. You have to exercise some restraint.

The most popular battery tenders on the Forum are CTEK, Deltran and Schumacher. All have various adapters for direct connection to the battery or the lighter plug. Various Forum Vendors carry these.

Deltran makes a version that will charge multiple vehicles with one unit. You can connect all your prizes to the same device and save a little.

 

KJ - thanks for additional feedback.

Currently I would have the Firestone tires for cold season and if new wheels and tires would have Mich and spyder replica's. Something is in the works though and I may switch cars. (OMG - DREAM COMING TRUE.)

My auto needs another part and is being shipped to Certified Mechanic at GM Dealership. I visited that dealership today - the folks were great and let me visit my car as long as I wanted. I took some piccies as they had the center dash panel off and pass carpet so they could get to componentry and I learned more about how to take this C6 a part.. LOL - My Dealer is letting me drive their LS3 to Bloomington this weekend - they will be taking 12-14 cars there.

FWIW - I built and wired my garage so I have duplex recepticles every 32" in the motorcycle (slightly climate controlled) portion of my garage. 1x1 is effective too if Deltran craps (which none have in more than a decade) out it is a $30 replacement as opposed to the multi units that cost 3 times more and have (unsigghtly and unsafe for marring plastic) wires to cross all around. Just a counterpoint - thanks for FEEDBACK!!!!!

 

Refresh of my post / highlight on outstanding questions and update follows (partial SNIPS but please feel free to read originals and respond to any / all. THANK YOU!!!!!

Echo questions:
1. Dealer says they are replacing my DIC.(?) I guess this is the DIC Switch? (They referenced a DIC Module??) Dealer suggested it is about a $500 part. (???)
2. They tell me DIC's (switch or module?) for 05-0x are on National Back Order?
3. Key Fobs MUST be "Replaced" to function with a new DIC Module??? (Retail for key fobs are approx $150+ / Dealer Cost approx $90+)
(Thread ref below suggests these can be reprogrammed! (wtf?)

Driver Information Center (DIC) Switch Inoperative

Circuit/System Description

The driver information center (DIC) switch is a multiplexed switch that functions as a DIC dimmer switch. Battery power is provided to the DIC switch via the instrument panel cluster (IPC) with the DIC switch signal circuit pulled up to battery voltage in the IPC. The IPC also provides the DIC switch with a ground. The switch input to the cluster is pulled low or grounded when a switch is activated. The DIC switch is a momentary contact switch that connects a series of resistors in a resistor ladder format. The IPC monitors the DIC switch signal circuit to determine the DIC switch inputs. Each switch state - Set/Reset, Fuel, Trip, Options, Gage - corresponds to a certain resistance value. The IPC determines the switch state by the voltage drop across the resistors.

1. I do not have my 06 Back yet; today is two weeks. I want my car. Still driving the loaner LS3 - started detailing it as I can't stand not doing so....
2. I expect to pick my O6 up today as as soon as I get the go sign. Sheesh - I hope they get all operable. This '2' hour service expectation has been extremely difficult on me.

I'll post later AND tie this thread to at least one of the others striving for additional feedback and enhancing understanding for all interested.

 

Got my car! So far I am favorably impressed. I'm trying to get a copy of the invoice.
