  Summary

  We are informing you that tool p/n 900100024 has been updated with an additional component designed to improve the oil seal installation process on V6 Nettuno engines. This added component helps ensure consistent, accurate positioning of the oil seal in its seat by compensating for dimensional gaps and seal tolerances.

  Summary

  Some vehicles may exhibit a concern related to the Remote Start timer. In these cases, the Body Control Module (BCM) may not correctly align the expected timer behavior with the vehicle’s actual response time. This timing mismatch can interrupt the procedure and cause the remote start function to fail. A software update is required to correct the timer settings and ensure the Remote Start procedure completes successfully.
