Condition Some customers may comment that a Service Side Detection System message is
displayed in the Driver Information Center {DIC) or DTC U0232, U0233 may be set.

the module and harness connectors should be
inspected for corrosion and replaced if needed (the
replacement harness will have a cover over the
connector body to protect the connection), and
dielectric grease applied accordingly to prevent any
concerns in the future.
