Do Jeep Owner Manuals Contain Diagnostic Codes?

Owner manuals, including those for Jeep vehicles, do not contain diagnostic codes. Diagnostic codes for Jeeps and other vehicles can be found inside the service repair manual, along with the troubleshooting tips required to solve them. Owner manuals are only for basic vehicular needs, such as resetting the radio or maintenance.

A service repair manual is a book used for vehicle repair. These books contain all the necessary information required in order to troubleshoot malfunctioning engine systems, unlike the owner's manual which focuses solely on the maintenance portion of the car. To retrieve a list of the diagnostic codes, purchase a Jeep repair manual from producers, such as Haynes or Helm Inc.
