CAUTION: Erasing the Diagnostic Trouble Codes may allow the
code reader to delete not only the codes from the vehicle's on-board
computer, but also "Freeze Frame" data and manufacturer
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.
This function is performed with key on engine off (KOEO). Do
not start the engine.
1) If you decide to erase the DTCs, use SCROLL button to select
Erase Codes from Diagnostics Menu and press ENTER/EXIT
button.

number of codes detected and type of codes (Generic or
Manufacturer specific, Stored or Pending codes) will be

If no codes are detected, a "No codes are stored in the
module!" message displays on the screen.
If retrieved DTCs contain any manufacturer specific or
enhanced codes, the display indicates "Manufacturer
control".
