Body Verification Test
Turn the ignition off.
Disconnect all jumper wires and reconnect all previously disconnected components and connectors.
If the Body Control Module was replaced, turn the ignition on for 15 seconds (to allow the new BCM to learn VIN) or engine may not start.
Program all RKE transmitters and other options as necessary.
With the DRB III(R), erase all Diagnostic Trouble Codes (DTCs) from ALL modules. Start the engine and allow it to run for 2 minutes. Operate all functions of the system that caused the original complaint.
Ensure that all accessories are turned off and the battery is fully charged.
Turn the ignition off and wait 5 seconds. Turn the ignition on and using the DRB III(R), read DTCs from ALL modules.
