Circuit/System Verification

WARNING: This page is about a different car, the 2008 Buick Lucerne. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition ON, verify the scan tool can communicate with both SOD sensors.
  2. Ignition ON, verify that the SOD system indicators located in the outside rearview mirrors illuminate briefly and turn OFF during the system self test.
    • If both SOD indicators do not illuminate briefly during the system self test and the DIC displays SIDE BLIND ZONE ALERT SYSTEM OFF, the SOD system has been disabled from the DIC by the driver and is operating normally.
    • If both SOD indicators illuminate and remain illuminated after the system self test and the DIC displays CLEAN SIDE BLIND ZONE ALERT SYSTEM, check for contamination on the fascia and sensor surface, making sure they are clean.
    • If the SOD indicators do not illuminate briefly during the self test, refer to Left SOD Indicator Malfunction  or Right SOD Indicator Malfunction  .
