Circuit/System Testing

WARNING: This page is about a different car, the 2007 Chevrolet Monte Carlo and 2007 Chevrolet Impala. However, it is still accessible from the selected car via links, so may be relevant.
    IMPORTANT: When removing connectors, inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected component/connector:
    • The SDM module
    • The SDM wiring harness connector
  1. Ignition OFF, remove the Air Bag fuse from the underhood fuse center. Ignition ON, engine OFF test the voltage from the supply voltage side of the AIR BAG fuse to a ground with a DMM. The voltage should read 9-16 volts.
    • If the voltage is less than 9-16 volts, correct the open or short on the voltage supply circuit or the open in the control side of the RUN/CRANK relay.
  2. Remove the SDM connector. With the air bag fuse removed, test the ignition 1 voltage circuit between the underhood fuse center and the SDM for a short to voltage or an open. Verify that a short to voltage or an open does not exist.
    • If any of the above conditions are found, make the appropriate repair.
    • If ignition 1 voltage circuit test normal then refer to Diagnostic Aids  within this repair.
  3. If all circuits test normal, replace the SDM.
