Pinpoint Test AZ: The Turn Signal On Warning Chime Is Inoperative

Normal Operation

The turn signal on warning chime sounds when the vehicle travels more than 3.2 km (2.0 miles) with the turn signal on. The Body Control Module (BCM) communicates the turn signal switch status to the IPC (Instrument Panel Cluster) over the High Speed Controller Area Network (HS-CAN) communication bus. The PCM communicates the odometer count data to the IPC (Instrument Panel Cluster) over the HS-CAN (High Speed Controller Area Network) communication bus.

This pinpoint test is intended to diagnose the following:

- Odometer operation

- Turn signal indication concern

- BCM (Body Control Module)

- IPC (Instrument Panel Cluster)
