TEST	ACTION	APPLICABILITY
1	Turn the ignition on. Turn the Radio on. With the DRBIII®, erase the audio DTC's. Cycle the ignition switch from off to on and wait 10 seconds. With the DRBIII®, read the audio DTC's. Does the DRBIII® display ALL OUTPUTS SHORT? Yes : Go To 2 No : Refer to the SCHEMATIC DIAGRAMS to help isolate a possible intermittent short. Perform BODY VERIFICATION TEST .	All
2	Turn the ignition off. NOTE: Perform this procedure after disconnecting each front speaker connector. Disconnect each front speaker harness connector one at a time. Turn the ignition on. Turn the radio on. With the DRBIII®, erase the audio DTCs. Cycle the ignition switch from off to on and wait 10 seconds. With the DRBIII®, read DTC's. Does the DRBIII® display ALL OUTPUTS SHORT with all the front speakers disconnected? Yes : Go To 3 No : Replace the Speaker that when disconnected the DTC did not reset. Perform BODY VERIFICATION TEST .	All
3	Turn the ignition off. NOTE: Perform this procedure after disconnecting each rear speaker connector. Disconnect each rear speaker harness connector one at a time. Turn the ignition on.
