My check engine light came on today and I have only had the car out of winter storage for 2 days.
I went through the automatic codes section of the DIC. In manual mode it showed the following "10 PCM 1 codes" yet I was unable to get the display to show me what code # It was. After numerous attempts, I accidently reset the code When I restarted the car, the check engine light didn't come back on. I only started the car and didn't drive it yet.
Any help out there? The check engine light light came on when I pulled back and held the high beam lever on my HID lights.

 

I wouldn't worry about it unless it comes back. If it does:

Reading Engine Diagnostic Codes

The Diagnostic Display Mode is entered with the following procedure:
1) Turn on the ignition but don't start the engine.
2) Press the RESET button to turn off any warning messages. (i.e. door or trunk open etc)
3) Press and hold OPTIONS
4) While holding OPTIONS, press FUEL four times within a 10-second period.

Initially, on-board diagnostics go into an Automatic Mode which shows diagnostic codes in a pre-set sequence: PCM - TCS - RTD - BCM - IPC - RADIO - HVAC - LDCM - RDCM - SCM - RFA. All codes will be displayed for each. ( i.e. PCM = 4 codes)

If none are present in a given module, you will see No More Codes on the display.

There are two kinds of diagnostic codes, Current and History designated with a letter suffix, C or ;H.

A current code indicates a malfunction is present in the module displaying data.

A history code indicates a problem existed sometime in the last 40 or 50 ignition cycles. When not accompanied by a current code of the same number, it's potential evidence of a previous problem, now resolved, that was not removed by clearing the codes. More likely it's an indication of an intermittent malfunction.

Intermittent codes are the most challenging of the diagnostics. An intermittent code may have happened once, may have happened more than once but is inconsistent or may be happening on a regular basis but not at the time the codes are displayed. History codes can also be caused by a current malfunction in a system that is not operating at the time codes are displayed. An example is the rear window defogger which doesn't operate until the Body Control Module detects engine rpm. For history codes set by a module that does not operate with the key on and engine off, a special diagnostic tool called a Scan Tester is necessary to properly diagnose the malfunction.

Once the system has displayed all modules, it goes into the manual mode which allows selection of each module using combinations of Driver Information Center buttons. Manual mode can also be entered during the automatic sequence by pressing any button except E/M.

Once the display shows Manual Diagnostics, select a module by pressing the OPTIONS button to go forward or the TRIP button to go back. Once a module is selected, a code is displayed, and if more than one are present;
press GAGES to go forward or FUEL to go back.

To exit the diagnostic mode at any time, press E/M. If you want to erase codes in a given module, press RESET

To 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 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. Clearing a code does not repair a problem. You are simply erasing the evidence of it in the module's memory. If you clear the code/s, and extinguish the Check Engine Light, your emissions status ready will NOT allow you to pass an emissions test until you have completed the required driving cycles.

 

Thanks pal, I should be able to narrow it down with info.

 

Being a simple person, I check the simple things first. When you took your car out of storage did you go get gas? Check the gas cap and make sure that it is on "right and tight". That's one of the first things that will make the check engine light come on. If it is okay, then I would do the in depth checks.
