B3094

CIRCUIT DESCRIPTION
The body control module (BCM) receives a vehicle security powertrain status message from the powertrain control module (PCM) through the Class 2 serial data link when turning the ignition switch ON.

CONDITIONS FOR SETTING THE DTC
The BCM sets DTC B3094 when the BCM does not receive a vehicle security powertrain status message from the PCM within one minute of turning the ignition switch ON.

ACTION TAKEN WHEN THE DTC SETS
- The BCM stores DTC B3094 in memory.
- The BCM sends a message to the instrument cluster to turn on the SECURITY indicator.

CONDITIONS FOR CLEARING THE DTC
- B3094 DTC status changes from current to history when the BCM receives the vehicle security powertrain status message from the PCM.
- A history DTC will clear after 100 consecutive ignition cycles if the condition for the fault is no longer present.

DIAGNOSTIC AIDS
- The following conditions may cause an intermittent malfunction to occur:
- An intermittent open in the class 2 serial data link between the BCM and the PCM
- Poor connections at the BCM, PCM, or the vehicle star connector
- If DTC B3094 is set as a current DTC, a serial data communication malfunction exists. Refer to Symptoms - Data Link Communications. Testing and Inspection
- DTC P1626 will set in the Powertrain Control Module (PCM) when the ignition switch is on with the BCM disconnected.
