Service Vehicle Soon

The instrument panel cluster (IPC) illuminates the service vehicle soon indicator during any of the following conditions:

• The body control module (BCM) detects a security failure. The BCM sends a class 2 message to the IPC requesting illumination.
• The BCM detects a malfunction in the Passive Trunk Release System. The BCM sends a class 2 message to the IPC requesting illumination.
• The BCM detects a failure in the Traction Control System. The BCM sends a class 2 message to the IPC requesting illumination.
• The IPC detects a mismatch between its part number and the vehicle platform configuration sent by the BCM via a class 2 message.
• The IPC receives a class 2 message from the BCM when certain malfunctions that are not related to the emissions system are detected.
• The powertrain control module (PCM) sends a serial data message to the BCM requesting illumination.
