I Have A 2004 With 28K on it and having problems with my security light staying on and the memory function not always working . Most of the time it works find. I Also Found That If I Hit The Unlock Button On my Key Fob That The Very Next Start The Security Light And Memory Functions Work Correctly. I tried to read the codes as stated below from another post but got nothing.
Tried cleaning the keys and even bought another new key.
WHAT DO I DO , Thanks

"Turn the key to the ON position, but don't start the engine. Clear any present messages by pressing the RESET button. Hold the OPTIONS button down, and press the FUEL button 4 times. This will get you into the CODES section of the DIC. The computer will automatically display all the codes your car has created. It will cycle through each code every 3 seconds. Any code that ends in H is a history code (something that has occured in the past) but is fine now. Once the computer has finished going through all of it's codes, press RESET to enter Manual Configuration mode. It should start with a module and show "NO CODES" or "# CODES".

To optionally reset the codes once in manual mode, press and hold RESET until it displays "NO CODES". Press OPTIONS to go to the next module. Repeat the steps in this paragraph until you have reset the codes in all the computer modules. NOTE !! Only reset the codes IF you want to - it is NOT necessary to do this."

Tried It It Didn't Work, That Link Is The Same Info Is I Wrote , What Am I Doing Wrong

 

That info is correct.

 

You are holding the OPTIONS button down while pressing the FUEL button, right? Use a nice deliberate press on the FUEL button. Not a quick jab.

 

it has worked for me every time....

 

I Will Try Again. And Yes I Was Holding The Option Button Down. It Just Will Not Work

 

are you making sure that you have all of the other messages cleared before you start?

also i always make sure i have the drivers door closed, so that message will clear too....

 

The directions you have are what I have seen posted here on the forum for a long time and they have always seemed to work. Can't explain why they are not working for you.

 

No ideas here either. Same way I've read my codes 5 or 6 times.

 

Ok I Got It
It Read
60-IPC 2 Codes
80-Raido 1 Code
10PCM 3 Codes
40-BCM 1 Code
58-SDM 1 Code
AO-LDCM 7 Codes
AL-RDCM 6 Codes

Now What Do I Do, Thanks For Your Help

 

Go though each set of codes and write them down.

 

All Codes Had An "H" After The Code Number I Assume They Are All Old Problems. Should I Clear All Codes?

60-IPC 2 Codes 2 2121, 2 2120
80-Raido 1 Code 2722
10PCM 3 Codes u1064, B0516, u1064
40-BCM 1 Code u1064
58-SDM 1 Code u1064
AO-LDCM 7 Codes B2252, B2282, B2286, B2284, B2264,
B2262, u1064
AL-RDCM 6 Codes B2239, B2283, B2287, B2285, B2263, u1064

 

Yes clear them all H means history see what comes up after you reset them and drive around for awhile. After awhile if you have some they will pop up then it's time to start diagnosing the problem(s)

 

Thanks

 

I Am Coming Uo With 2 Codes That Will Not Reset
10 PCM
P2120 H C
P2121 H C
What Next
It Sat For 3 Days When I Went It Turn The Key It Read Low Voltage , I Tested The Battery It Had 12 Volts. I Put The Charger On It And It Only Took 20 Min To Bring it Up to A Full Charge. I Did Notice The Negative Battery Term. Was A Little Lose

 

Do you know what these code are and would you like to know!I can tell you! Just need to look them up in my book!

 

Yes Please Tell Me, Does You Book Tell You What to Do Next

 

let me look it up and I will answer you back.

 

In my manual i found that a c2120 and c2121 is a TPM system malfunction (no sensors Received) The book say's CONDITION FOR SETTING THE DTC.The vehicle completes a diagnostic cycle (driving for about 20 min. at speed over 15mph. The receiver has not received any TPM sensor information. these condition must be present for 20 min.So action is taken when the DTC sets, H FOR HISTORY DTC will clear after 50 consecutive ignition cycles if the condition for the malfunction is no longer present.This is related to tire pressure.
