Service Vehicle Soon Indicator

The SERVICE VEHICLE SOON indicator can be controlled by the Electronic Brake Control Module/Electronic Brake Traction Control Module (EBCM/EBTCM), the Powertrain Control Module (PCM), or the Body Control Module (BCM) over the class II serial data line.

The SERVICE VEHICLE SOON indicator will turn on to warn the driver that a malfunction exists within the ABS, BCM, or PCM systems which may degrade overall vehicle performance. For more information on ABS, refer to Antilock Brake System. For more information on the BCM, refer to Body Control Module. For more information on the PCM, refer to Engine Controls.
