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
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
signal from a sensor that indicates
the sensor has failed and is
completely 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.
Most Ford EEC-IV vehicle computers up to 1991 use a two-
digit code system. From 1991 to 1995 most use a three-digit
code system.
11. If no problems are found during the
KOER Self-Test, the computer sends a
"PASS code" (code 11 or 111) to the
CanOBD2&1 Scan Tool. Code 11 or
111 indicates that all the relays and
actuators and their related circuits that
were tested during the KOER Self-Test
are OK, and no faults were found.
12. After the CanOBD2&1 Scan Tool retrieves all the KOER Self-Test
DTCs, turn the engine off, and disconnect the CanOBD2&1 Scan
Tool from the vehicle's test connectors. The DTCs retrieved are now
stored in the CanOBD2&1 Scan Tool's memory.
