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.
Cause This condition may occur with water intrusion into the Side Blind Zone Module harness connector, and may cause corrosion of the terminals or water seepage into the module.



If the vehicle displays the subject message or codes, 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.


Service Procedure:

harness (1) and module (2) connectors

  1. Inspect the harness (1) and module (2) connectors for corrosion. If no issues are found, refer to Side Blind Spot Alert System Malfunction in SI.
  2. If either harness or module connectors show signs of corrosion, replace the harness and both modules. Refer to Side Object Sensing Alert Module Replacement in SI.

GM Dielectric Lubricant

Note: Only GM Dielectric Lubricant must be used for this procedure. No substitutions are allowed.

  1. Lubricate the harness and module connectors with dielectric lubricant to ensure corrosion-free connections.
