2001 Chevrolet Venture Base, Van Cargo ExtendedSECTION Programming New Body Control Module (BCM)
NOTE: New modules are unprogrammed. New module must be programmed with code that matches customer's key for PASS-Key® II operation. New module can only be programmed once.
  1. To program a NEW Body Control Module (BCM), install new module into vehicle. Insert customer's key into ignition lock cylinder and turn to RUN position. Start engine to verify operation.
  2. Observe SECURITY indicator. SECURITY indicator should illuminate for about 5 seconds and go out (BCM is programmed). If SECURITY indicator flashes one flash per second and engine starts, check wiring, contacts to key resistance pellet, and key for defects or intermittents. Repair or replace as necessary. Repeat procedure because module did not program key code.
