Pinpoint Test AN: The Memory Feedback Warning Chime Is Inoperative

Normal Operation

The Instrument Panel Cluster (IPC) receives the memory feedback chime request from the Driver Seat Module (DSM) over the Medium Speed Controller Area Network (MS-CAN) communication bus. When a successful memory set procedure is carried out, the DSM (Driver Seat Module) sends a chime request to the IPC (Instrument Panel Cluster) to sound the memory feedback chime.

This pinpoint test is intended to diagnose the following:

- Key-in-ignition warning chime concern

- Memory set feature concern

- DSM (Driver Seat Module)
