The first code displayed by the Code Reader is the
Cylinder Identification (ID) Code. The cylinder ID
code identifies the number of cylinders of the vehicle
that is under test.
A small "R" will show in the upper right hand corner
of the display to indicate that the code being retrieved
is a Key On Engine Running (KOER) code.
NOTE: If all the procedures are followed and the Code
Reader fails to work, refer to "Troubleshooting" on
page 75.
6. Test the knock sensor (if applicable) after the cylinder ID
code is transmitted. Place a steel shaft near the bottom of
the knock sensor (not on the sensor). With a light
hammer, knock slowly on the end of the shaft for 15
seconds.
NOTE: For vehicles equipped with knock sensors:
Code 25 may display if the knock sensor test in step 6
is not performed.
7. If any problems are detected on any components or
circuits as they are being tested, a numerical code
(Diagnostic Trouble Code) will be sent to the Code Reader.
After all the KOER Self Test Codes are received by the
8.
Code Reader (wait until the flashing square icon no longer
appears on the screen for 30 consecutive seconds to ensure
that all the codes have been retrieved), turn the Code
Reader off.
9. Turn the engine off and disconnect the Code Reader from
the vehicle's test connector. The codes received are now
stored in the Code Reader's memory.
10. To view codes stored in the Code Reader's memory, press
the ON/OFF button to turn the Code Reader on, then
press and release the MEMORY button; the first stored
code will display. Continue pressing and releasing the
MEMORY button to scroll through the stored codes until
all the codes have been displayed.
NOTE: All retrieved codes will stay in the Code Reader's
memory and will only clear from the Code Reader's
memory if the Self Test procedure is performed again
(codes from a prior test will clear automatically when new
Self Test is performed) or if batteries are removed from the
Code Reader.
