Using The I/M Readiness Monitor Status To Confirm A Repair - Innova 3100 Owner's Manual

Using Code Reader
I/M READINESS TESTING
Repair the vehicle yourself. If you are going to perform the
repairs yourself, proceed by reading the vehicle service manual
and following all its procedures and recommendations.
Take the vehicle to a professional to have it serviced. The
problem(s) causing the red LED to light must be repaired before
the vehicle is ready for an Emissions Test (Smog Check).

Using the I/M Readiness Monitor Status to Confirm a Repair

The I/M Readiness Monitor Status function can be used (after repair
of a fault has been performed) to confirm that the repair has been
performed correctly, and/or to check for Monitor Run Status. Use the
following procedure to determine I/M Readiness Monitor Status:
1. Using retrieved Diagnostic Trouble Codes (DTCs) and code
definitions as a guide, and following manufacturer's repair
procedures, repair the fault or faults as instructed.
2. After the fault or faults have been repaired, connect Code Reader
to the vehicle's DLC and erase the code or codes from the
vehicle's computer memory.
See page 20 for procedures to erase DTCs from the vehicle's
on-board computer.
Write the codes down on a piece of paper for reference before
erasing.
3. After the erase procedure is performed, most of the Monitor icons
on the Code Reader's LCD display will be flashing. Leave Code
Reader connected to the vehicle, and perform a Trip Drive Cycle
for each "flashing" Monitor:
Misfire, Fuel and Comprehensive Component Monitors run
continuously and their icons will always be on solid, even
after the erase function is performed.
Each DTC is associated with a specific Monitor. Consult the
vehicle's service manual to identify the Monitor (or Monitors)
associated with the faults that were repaired. Follow the
manufacturer's procedures to perform a Trip Drive Cycle for the
appropriate Monitors.
While observing the Monitor icons on Code Reader's LCD
display, perform a Trip Drive Cycle for the appropriate Monitor or
Monitors.
If the vehicle needs to be driven in order to perform a
Trip Drive Cycle, ALWAYS have a second person help
you. One person should drive the vehicle while the other
person observes the Monitor icons on Code Reader for
Monitor RUN status. Trying to drive and observe Code
Reader at the same time is dangerous, and could cause
a serious traffic accident.
