Circuit/System Verification

WARNING: This page is about a different car, the 2010 Cadillac STS. However, it is still accessible from the selected car via links, so may be relevant.
  1. Verify that RVS is enabled through vehicle personalization.
    • If RVS is not enabled, use vehicle personalization to turn on RVS functionality. Refer to the vehicle owners manual.
  2. Verify that the keyless entry functions (lock, unlock, and panic) operate with all available keyless entry transmitters.
  3. Observe the scan tool ECM RVS Disable History parameters. Verify that no RVS Disable History items are present.
    • If RVS Disable History items are present, refer to the applicable subsection in which the failure occurred.
  4. Verify the scan tool RIM Current CTD Trigger parameter displays None.
  5. Inspect the external RF antenna connection at the RCDLR. First, gently pull on the coax connector at the module. If the coax comes out, then it wasn't seated properly. Remove and carefully inspect the coax connection for bent blades or a bent center pin. Fix coax connection if necessary and re-seat connector until a "click" is heard. Gently pull on the coax connection to make sure it is seated properly.
