DIAGNOSTIC TROUBLE CODES (DTCs)

47156 15

Manufacturer-Specific DTCs are codes that are controlled by
the vehicle manufacturers. The Federal Government does not
require vehicle manufacturers to go beyond the standardized
generic DTCs in order to comply with the new OBD2 emissions
standards. However, manufacturers are free to expand beyond
the standardized codes to make their systems easier to
diagnose.

The 3rd character is a letter or a numeric digit (0 thru 9, A thru F).
It identifies the specific system or sub-system where the problem is
located.

The 4th and 5th characters are letters or numeric digits (0 thru 9, A
thru F). They identify the section of the system that is malfunctioning.
