Erasing Diagnostic Trouble Codes (Dtcs) - Innova CarScan Owner's Manual

Using the Scan Tool

ERASING DIAGNOSTIC TROUBLE CODES (DTCs)

If more than one malfunction is present that causes more than
one DTC to be set, only the code with the highest priority will
contain Freeze Frame data. The code designated "01" on the
Scan Tool display is referred to as the PRIORITY code, and
Freeze Frame data always refers to this code. The priority
code is also the one that has commanded the MIL on.
13. When the last retrieved DTC has been displayed and DTC/FF is
pressed, the Scan Tool returns to the "Priority" Code.
14. Determine engine system(s) condition by viewing the display for any
retrieved Diagnostic Trouble Codes, code definitions and Freeze
Frame data, and interpreting the green, yellow and red LEDs.
If DTC's were retrieved and you are going to perform the repairs
yourself, proceed by consulting the Vehicle's Service Repair
Manual for testing instructions, testing procedures, and flow
charts related to retrieved code(s).
ERASING DIAGNOSTIC TROUBLE CODES (DTCs)
When the Scan Tool's ERASE function is used to erase
DTCs from the vehicle's on-board computer, "Freeze
Frame" data and manufacturer-specific enhanced data are
also erased. "Permanent" DTCs ARE NOT erased by the
ERASE function.
If you plan to take the vehicle to a Service Center for repair, DO NOT
erase the codes from the vehicle's computer. If the codes are erased,
valuable information that might help the technician troubleshoot the
problem will also be erased.
Erase DTCs from the computer's memory as follows:
When DTCs are erased, the I/M Readiness Monitor Status
program resets status of all Monitors to a not run condition. To
set all Monitors to a DONE status, an OBD2 Drive Cycle must
be performed.
1. If not connected already, connect the
Scan Tool to the vehicle's DLC, and
turn the ignition "On." (If the Scan Tool
is already connected and linked to the
vehicle's computer, proceed directly to
step 3. If not, continue to step 2.)
2. Perform the Code Retrieval procedure
as described on page 6.
To erase OBD2 DTCs: Wait until
the codes are displayed,
proceed to step 3.
