Service Vehicle Soon
The IPC illuminates the SERVICE VEHICLE SOON indicator when the
following occurs, or other problems depending on model and year:
1: The body control module (BCM) detects certain malfunctions in the
lighting system. The IPC (Instrument Panel Cluster) receives a class 2
message from the BCM requesting illumination. The IPC sends a class 2
message to the BCM indicating that the service vehicle soon indicator is
illuminated. The BCM sends a class 2 message to the radio in order to
activate an audible warning.
2: The Electronic Brake Control Module (EBCM) detects a malfunction in
the traction control system. The IPC receives class 2 messages from the
EBCM requesting illumination of both the service vehicle soon and traction
off indicators.
2: The IPC performs the displays test at the start of each ignition cycle. The
indicator illuminates for approximately 3 seconds.
3: The IPC detects a loss of class 2 communications with the BCM.

| Basically this warning comes on when the Body Control Module(BCM) sees a problem in the systems listed above, or other computer systems, depending on model and year of vehicle. Todays vehicle computers TALK to each other and report problems they see in the systems that they monitor. Class 2 refers to the circuit that these computers talk on. |
