NOTE: If code 98 or 998 dis-
plays instead of a cylinder ID
code, 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.
8. Check your vehicle's service manual to see if your vehicle
is equipped with a Power Steering Pressure Switch, Brake
On/Off (BOO) Switch and/or an Overdrive Cancel Switch.
If your vehicle is equipped with these features, perform
the following immediately after retrieving the Cylinder ID
code (step 7).
NOTE: If you are unsure of your vehicle's equipment, it is
recommended that you perform these procedures anyway.
If your vehicle has a Power Steering Pressure Switch
(PSPS), turn the steering wheel a half turn; wait
three to five seconds, then release. The computer
checks for proper variations in power steering
pressure during this procedure. Failure to perform
this procedure will generate a Fault Code.
If your vehicle has a Brake On/Off (BOO) Switch, step
on the brake pedal once, and release. The computer
checks the Brake On/Off Switch for proper operation
during this procedure. Failure to perform this
procedure will generate a Fault Code.
If your vehicle has an Overdrive Cancel Switch (OCS),
turn the switch on and off once. Failure to perform
this procedure will generate a Fault Code.
Thirty to sixty seconds after the cylinder ID code is re-
9.
ceived, code 10 may display (code 10 is not applicable to all
vehicles). If a code 10 is displayed, quickly press the accel-
erator pedal to the floor and release, then proceed to step
10. If code 10 is not displayed proceed directly to step 10.
