Here are some steps which you should follow in order to diagnose this fault code:

• The P0631 error code can be diagnosed by utilizing an OBD-II trouble code scanner.
• A scanner should be used by a professional technician to notice the freeze frame data, to assemble details about the code.
• The mechanic can also check to see if there is presence of additional trouble codes.
• Now if there are a number of codes, then they should be addressed in the same order in which they are appearing on the scanner.
• After that the mechanic should reset the trouble codes, restart the vehicle, and check to see if the code remains detected.
• If it does not, then the code was likely triggered incorrectly, or represents an intermittent issue.
• Clear the codes and then run the vehicle to check if its returns.
• This would be very helpful in determining if the malfunction is intermittent or not.
• Once the codes have been cleared up, then the vehicle should be taken out for a test drive to check if the codes return.
• It can be quite challenging to diagnose the intermittent conditions and in some extreme situations it might get worse before attempting the right diagnosis.
• The latest OBD-II systems are programmed in such a way that they function in only one specific automobile.
• The automobiles pertinent data is programmed into the PCM. This would then be shared with the other control modules via the CAN bus network
• Now if there is a replacement of the control module, then make sure to reprogram it to match the automobile.
• The process of reprogramming the control module includes the type of vehicle, its identification number, mileage as well as anti theft settings. You can always use a specialized scanner or an Autohex to easily diagnose the cause of this code.

Common Mistakes When Diagnosing The P0631 Code
