Code Description
A "Configuration Error" code displays when the system
has re-loaded the system defaults into ECU memory,
eliminating
any
changes
(target
pressures,
etc.)
previously programmed via a diagnostic tool. This code
will also display on systems which have harness
selected
the
download
configuration
and
not
programmed any values into the ECU yet.
The ECU will re-load its memory anytime the harness
configuration selection changes. This allows the ECU to
be moved from vehicle to vehicle and change its
interaction with those vehicles as needed. On all
systems (except harness selected download config),
pressing the HWY and RUN FLAT buttons at the same
time will clear the display.
The troubleshooting procedure involves verifying that the
harness configuration selection wires are making a good
connection. If the configuration wires are good, and the
problem repeatedly occurs, the ECU may need to be
replaced.
