CODE RETRIEVAL PROCEDURES - KOER TEST
6. When prompted by the CanOBD2&1
Scan Tool, start the engine and press
the ENTER/LD button to continue.
A "One moment please KOER test is in
progress..." message shows temporarily
on the CanOBD2&1 Scan Tool's display.
7. The CanOBD2&1 Scan Tool will retrieve
and display the Cylinder Identification
(ID) Code. The Cylinder ID Code identi-
fies the number of cylinders of the vehi-
cle that is under test.
If the CanOBD2&1 Scan Tool fails to
retrieve CYL ID and DTCs, its possi-
ble that the KOEO Test was not per-
formed properly before proceeding to the KOER Test.Go back and
perform the KOEO Test (page 70) until a PASS code is obtained.
8. Perform the following procedures when prompted by the message
on the CanOBD2&1 Scan Tool's display.
■ Turn the steering wheel 1/2 turn to right, hold for four seconds
and release.
■ Press the brake pedal to the floor and then release it.
■ Cycle the Overdrive Switch (if equipped).
■ Quickly press the accelerator pedal to the floor and then release it.
9. After the above procedures are performed
a "One moment please KOER test is in
progress..." message shows temporarily
on the CanOBD2&1 Scan Tool's display,
followed by a "Retrieving codes" message.
10.If the CanOBD2&1 Scan Tool was able
to link to the vehicle successfully, a
“Code retrieval was successful...” message shows temporarily on the
CanOBD2&1 Scan Tool’s display, followed by any retrieved DTCs.
If code 98 or 998 displays, the
vehicle is operating in "Failure
Mode". The computer goes into
failure mode when it detects a sig-
nal from a sensor that indicates
the sensor has failed and is com-
pletely out of specifications. The
computer substitutes a fixed signal
value for the failed sensor to keep the vehicle running. Failure
mode codes 98 or 998 are usually accompanied by one or
more Diagnostic Trouble Codes that indicate the failed sensor.
A vehicle operating in failure mode is operating at a minimal
level, and the faults that are causing these Diagnostic Trouble
Codes to set must be repaired as soon as possible.
