PINPOINT TEST AZ: ALL THE CHIMES ARE INOPERATIVE

Test AZ1-AZ2:

Normal Operation
The warning chime is an integral part of the instrument cluster. The instrument cluster sounds the warning chimes after receiving hardwired and data signal inputs from the vehicle security module and the restraint control module (RCM). Data input signals are transmitted to the instrument cluster over the standard corporate protocol (SCP) communication network, circuits 914 (TN/OG) and 915 (PK/LB) and the UART based protocol (UBP) communication network, circuit 693 (OG).

Possible Causes
- circuitry
- instrument cluster
