Displaying Flash Codes using a Jumper Wire.
WARNING: This page is about a different car, the 2004 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.
Connect a jumper between cavity 4 and cavity 13 with the ignition ON, and the engine OFF. This action pulls the cruise control module (CCM) terminal 10 to ground and signals the CCM to enter the FLASH DTC diagnostic display mode.
