C5 DTC Code Meanings

C5 DTC Code



Due to the large amount of C5 Corvette codes, information and complexity, our book C5 Corvette Book of Knowledge offers you way more information then can be displayed on any web browser! It includes along with C5 DTC Code info, production quantities, torques specs, common problems, recall info, performance data, road test and buyers inspection checklists. As an added bonus we also include a winter storage checklist! This saves you months searching the internet and potentially large sums of your hard earned money.


C5 DTC Code Retrieval Procedure

Here is an overview of the procedure and terms used for resetting codes.

To display C5 DTC Code diagnostic trouble codes for all modules that transmit them. 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.

3) Press and hold OPTIONS.

4) While holding OPTIONS, press FUEL four times within a 10-second period.

NOTE!! Only reset the C5 DTC Code IF you want to it's 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. Once you have the codes, the next question is: What to do with the information? First, consult the factory service manual.

You should be 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 occurred 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 a list a DTC CODES in order for that Module.

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. But remember some codes will affect drive ability of the car if present! Clearing them may give you a fresh start to troubleshoot.
