Pinpoint Test AL: 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 Smart Junction Box (SJB) communicates the turn signal switch status to the Instrument Panel Cluster (IPC) over the Medium Speed Controller Area Network (MS-CAN). The IPC receives the odometer rolling count data from the PCM over the High Speed Controller Area Network (HS-CAN).

This pinpoint test is intended to diagnose the following:

- Odometer concern
- IPC
