Pinpoint Test 4

PINPOINT TEST 4: THE TURN SIGNAL ON 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 over the medium speed controller area network (MS-CAN). The PCM communicates the odometer count data to the instrument cluster over the high speed controller area network (HS-CAN).

Possible Causes
- Odometer operation
- Instrument cluster
