Hey guys

so owned this car about a month, been dirving it quite regularly as were getting great weather here.

Anyways today after about 5 minutes of driving the engine light comes up and its been there ever since.

I pulled the codes and this is what ive got:

1. 10-PCM- PO442 HC
2. A1 RDCM- 5 codes -B2283 H-B2285 H- B2263 H- B2265 H-U1064 H
3. A0-LDCM- 2 codes- B2282 H - U1064 H
4. B0-RFA - 7 codes - B0605 H - U1255 H - U1096 H- U1064 H - U1016 H - C2110 H- C2115 HC

Im googling them all to find out but getting led around to confusing threads with mixed messages.

Can anyone help me diagnose these please?

Thanks a lot in advance


Oh and by the way , the car seems to be running fine, but its burning a hell of a lot more fuel then it should, I thought it was the 02 sensors but what do I know ......

Did you put gas in today? Check,the gas cap tighten till it clicks several times. Also,the drivers door grab the black accordian tube and shake it. Restart the car and clear all codes, drive it then recheck for any codes and let us know.

Will do , thank you sir

Oh and to top it all off , while checking my codes I was so stressed out I locked the keys in the car, im now waiting for a locksmith to get them for me.

First, check the battery. These cars will show many false codes when a battery is on its way out. Second, have a spare key in the house.

No need to top it off, just make sure the cap is tight. If you were working on the car with the hood or doors open for a while also charge the battery, as mentioned these cars do not like low voltage.

Would ignoring the - change oil- and 0% oil life left trigger a check engine light eventually?

The car was originally at 8% oil life left, then it went down to 0% eventually - then it started reading -CHANGE OIL NOW- would this cause a check engine light eventually?

Ive ignored it because the previous owner used synthetic and the oil is still fine,

Thanks

Looks like to me, most , if not all of those codes are old codes. That's what the "H" is after them. As stated above, it looks like they're probably associated with a low or dead battery. Clear the codes and see if any of them show up again.

1Willy1

ahhh ok I was wondering what those mean , I will reset everything as bill advised and ill report back with whats new

The oil gauge is programed assuming synthetic oil - the Corvette recommendation is Mobil-1. Unless the oil was changed and the gauge not reset the car is due for an oil change.

If you have an older car with the passive system on, you can shake the car to unlock it.

Good to know , the owner told me he uses an oil called "amsoil" or something like that , and although he said I should still follow the recommended schedule, he said it is not a problem to go a little longer as the oil is good for an extra 1-2k kilometres.

lol good one.

Well I do have some good news , after resetting all the codes, the engine light has went away.

I took it for a hard drive, giving it lots of gas and foot , and so far so good.

Thanks a lot for the help guys , the quick responses were great.

The bad news is it cost me $75 to get my damn keys out of the car

Mr.Bill

75 bucks, Next time use a coat hanger and push the unlock button and get a spare key.

1Willy1

yep, as soon as I saw him do it I slapped myself , I could of done it myself easily.

A new key is around 20 bucks at the dealer...worthwhile investment.

You can pull the battery out and the battery mount / holder. Look at the cable trunks under the battery mount. They may have acid all over them. I've read that this causes many erroneous codes. Mine had acid on the cable sets

Don't worry about the RDCM and LDCM codes unlless windows and door locks are misbehaving. Anyway they are all history. Write them down, clear them and see if anything comes back.

If the car tells you to change the oil, and you have no idea when it was last changed, change the oil. Don't go for any spirited drives etc, change the oil

BTW, once you change the oil, if the DIC hasn't been reset, you can reset it by turning on the ignition (don't start car) and press the accelerator 3 times and the oil life will reset to 100 %.

Now change the oil

I recommend you pull codes while the engine is still RUNNING. Most codes will only show as H and not C if they are pulled after the car is shut off. Also some codes will no even show up like some related t the EBCM once the engine is off..
