Conditions for Clearing the DTC



* A current DTC clears when the conditions for setting the DTC are no longer present and the ignition has been cycled from OFF to ON.



* A history DTC clears after 50 malfunction-free ignition cycles.

Circuit/System Verification



Radio ON, adjust the fade and balance controls on the radio to test all channels individually. Each channel should produce clear and even sound.



Circuit/System Testing



1. Ignition OFF, disconnect the X1 and X2 connectors at the amplifier.



2. Radio ON, test for less than 1 volt between the appropriate signal circuit terminal listed below and ground:



* Left front tweeter speaker output (+) - terminal 4 X2



* Left front tweeter speaker output (-) - terminal 5 X2



* Right front tweeter speaker output (+) - terminal 7 X2



* Right front tweeter speaker output (-) - terminal 6 X2



* Left rear speaker output (+) - terminal 16 X2



* Left rear speaker output (-) - terminal 8 X2



* Right rear speaker output (+) - terminal 15 X2



* Right rear speaker output (-) - terminal 14 X2



* Front center speaker output (+) - terminal 13 X2



* Front center speaker output (-) - terminal 12 X2



* Left rear subwoofer speaker output (+) - terminal 5 X1



* Left rear subwoofer speaker output (-) - terminal 6 X1



* Right front speaker output (+) - terminal 7 X1



* Right front speaker output (-) - terminal 3 X1



* Left front speaker output (+) - terminal 1 X1



* Left front speaker output (-) - terminal 2 X1



* Right front speaker output (+) - terminal 7 X1



* Right front speaker output (-) - terminal 3 X1



* Left rear midrange speaker output (+) - terminal 11 X2



* Left rear midrange speaker output (-) - terminal 10 X2



瀚慖f greater than the specified range, test both circuits of the affected speaker for a short to voltage.



3. Radio ON, test for greater than 1 ohm between the appropriate signal circuit terminal listed below and ground:



* Left front tweeter speaker output (+) - terminal 4 X2



* Left front tweeter speaker output (-) - terminal 5 X2



* Right front tweeter speaker output (+) - terminal 7 X2



* Right front tweeter speaker output (-) - terminal 6 X2



* Left rear speaker output (+) - terminal 16 X2



* Left rear speaker output (-) - terminal 8 X2
