Using the Scan Tool
I/M READINESS TESTING
60 3040e
On some vehicle models, the computer will store non-emission
related DTCs. These DTCs will not command the MIL on since
they are not emission related. If the Scan Tool retrieves one of
these types of codes, the MIL will not be commanded on, and
the Yellow LED on the Scan Tool will be illuminated. In most
cases, these types of codes will not prevent the Emissions
Test from being performed.
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 defini-
tions 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 the Scan Tool to
the vehicle's DLC and erase the code or codes from the vehicle's
computer memory.
See page 50 for procedures for ERASING DIAGNOSTIC
TROUBLE CODES (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 Scan Tool’s LCD display will be flashing. Leave the Scan Tool
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 the Scan Tool’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 the Scan Tool for
Monitor RUN status. Trying to drive and observe the Scan
Tool at the same time is dangerous, and could cause a
serious traffic accident.
