red LED to light must be repaired before an Emissions Test (Smog
Check) can be performed. It is also suggested that the vehicle be
inspected/repaired before driving the vehicle further.
When inspecting a used vehicle before buying or selling:
A GREEN LED indicates that all emissions-related systems are
"OK" and operating normally. You can feel confident that these
vehicle systems are mechanically sound. Always BE SURE to
check other vehicle systems NOT covered by Code Reader
(transmission, brakes, etc.) as well as the vehicle's service record
before buying or selling a vehicle.
A YELLOW LED indicates a "Pending" DTC is present and/or
some of the vehicle's emission monitors have not run their
diagnostic testing. Further testing and evaluation may be needed
to determine the vehicle's actual condition.
A RED LED indicates there is a problem with one or more of the
vehicle's systems. It is recommended that you take the vehicle
qualified service technician for further diagnosis.
If no codes were retrieved and/or the green lights, and all your
vehicle's Monitors show a "Has Run" status, you're "good to go." You
can feel confident that:
The systems and components monitored by your vehicle's on-
board computer are in good working order and running properly.
Your vehicle should pass an Emissions Test (Smog Check)
without problem.
If codes were retrieved and/or the yellow or red LEDs light, you
can choose to:
Fix the problem yourself: If you choose to fix the problem
yourself, read and follow all of the vehicle service manual's
recommendations and procedures.
Take your vehicle to an Automotive Service Center for repair:
Take your vehicle, a copy of the completed Preliminary Vehicle
Diagnosis Worksheet (see page 14) and codes retrieved to your
technician for evaluation. This will show your technician that you
are an informed motorist and will also assist him in pinpointing the
location of the problem as a starting point for needed repairs.
If the red LED lights after retrieving codes or performing an
I/M Readiness inspection, it is suggested that the vehicle be
inspected/repaired before driving the vehicle further.
