Pinpoint Test AX: 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 Cluster (IC) over the Medium Speed Controller Area Network (MS-CAN). The PCM communicates the odometer count data to the IC over the High Speed Controller Area Network (HS-CAN).

This pinpoint test is intended to diagnose the following:

- Odometer operation
- IC



PINPOINT TEST AX: THE TURN SIGNAL ON WARNING CHIME IS INOPERATIVE

-------------------------------------------------
AX1 CHECK THE KEY-IN-IGNITION WARNING CHIME OPERATION


- Ignition OFF.
- With the ignition switch in the OFF position and the key in the ignition lock cylinder, open the LH front door and observe the key-in-ignition warning chime operation.
- Does the key-in-ignition warning chime operate correctly?

Yes
GO to AX2.

No
INSTALL a new IC. REFER to Instrument Cluster (IC) Instrument Cluster (IC). TEST the system for normal operation.

-------------------------------------------------
AX2 CHECK THE TURN SIGNAL INDICATORS OPERATION


- Ignition ON.
- Verify the turn signal indicators operation.
- Do the turn signal indicators operate correctly?

Yes
GO to AX3.

No
GO to Pinpoint Test W. Pinpoint Test W: The LH/RH Or High Beam Turn Indicator Is Never/Always On

-------------------------------------------------
AX3 CHECK THE ODOMETER FOR CORRECT OPERATION


- Drive the vehicle and observe the odometer for correct operation.
- Does the odometer operate correctly?

Yes
GO to AX4.

No
GO to Pinpoint Test K. Pinpoint Test K: The Odometer Is Inoperative

-------------------------------------------------
AX4 CARRY OUT THE TURN SIGNAL ON WARNING CHIME ACTIVE COMMAND USING THE SCAN TOOL


- Enter the following diagnostic mode on the scan tool: IC DataLogger .
- Select the IC turn signal on warning chime (CHIME_TS_ON) active command. Command the turn signal on warning chime on.
- Does the turn signal on warning chime sound?

Yes
GO to AX5.

No
INSTALL a new IC. REFER to Instrument Cluster (IC) Instrument Cluster (IC). TEST the system for normal operation.

-------------------------------------------------
AX5 VERIFY IC CONFIGURATION


- If a new IC was installed, make sure the correct module parameters were used when carrying out the Programmable Module Installation (PMI) procedure. If necessary, configure the IC to enable the turn signal on chime using As-Built data. Refer to Information Bus.
- Does the turn signal on chime operate correctly?

Yes
The system is operating correctly. The IC was incorrectly configured.

No
INSTALL a new IC. REFER to Instrument Cluster (IC) Instrument Cluster (IC). TEST the system for normal operation.
