Before You Start
•
Before scanning a vehicle, the EZ-SCAN scanner must be
correctly configured for your vehicle. Refer to “Setup /
Operating Instructions” on page 8 if you need to configure
the scanner.
•
Make sure to read these instructions completely before the
KOER test is started. Several user interactions may be
required during the scan. If these steps are not completed
correctly, the engine computer will store a Trouble Code as
if the system was not functioning properly. If one of these
trouble codes are stored,
repeat the scan with the nec-
essary steps to eliminate the
problem. For example, the
error
RPM too low dur-
ing KOER test
can be
corrected by pressing the gas
pedal to the floor during the
Dynamic Response section of
the scan.
Key ON, Engine Running
(KOER) Scan
The KOER scan causes the vehicle
EEC-IV computer to test the different
sensors and computer controlled
functions while the
vehicle engine is running.
1. Run the engine until it is at normal
operating temperature.
2. Make sure ALL electrical loads
(blower fan, air conditioning, radio,
etc.) are OFF.
