Audible Warning Device: Testing and Inspection
However, the tests may not prove conclusive in the diagnosis of this system. In order to obtain conclusive testing of the chime warning system, the
Programmable Communications Interface (PCI) data bus network and all of the electronic modules that provide inputs to, or receive outputs from the
chime warning system components must be checked.
The most reliable, efficient, and accurate means to diagnose the chime warning system requires the use of a DRB scan tool and the proper Diagnostic
Procedures. The DRB scan tool can provide confirmation that the PCI data bus is functional, that the Body Control Module (BCM) is sending and
receiving the proper messages on the PCI data bus, and that the BCM is receiving the proper hard wired inputs to perform its chime warning system
functions.
