Inspection and Verification

This information provides step-by-step module configuration procedures. Carry out PROGRAMMABLE MODULE INSTALLATION (PMI) in this information when another service information article directs to carry out configuration or when DTCs from the chart are present.

NOTE: Some modules on this vehicle utilize a 5-character DTC followed by a 2-character failure-type code. The failure-type code provides information about specific fault conditions such as opens, or shorts to ground. Continuous Memory DTCs have an additional 2-character DTC status code suffix to assist in determining DTC history.
