Erase Codes
NOTE
1. Erasing the Diagnostic Trouble Codes may allow 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.
2. Erasing codes does not mean that trouble codes in ECU have been
eliminated completely. As long as there is fault with the vehicle, the
trouble codes keeps on presenting.
3. This function is performed with key on engine off (KOEO). Do not start
the engine.
1) Use the UP/DOWN scroll buttons to select Erase Codes from
Diagnostics Menu and press the OK button.
2) A warning message comes up asking for your confirmation.
