4.2 Erasing Codes

CAUTION: Erasing the Diagnostic Trouble Codes allows the Scan

Tool to delete not only the codes from the vehicle’s on-board

computer, but also “Freeze Frame” data and manufacturer

specific enhanced data. Further, the I/M Readiness Monitor Status

for all vehicle Monitors is reset to Not Ready or Not Complete

status. Do not erase the codes before the system has been checked

completely by a technician.
