For a complete wiring diagram Refer to Section 8W.When Monitored:With the ignition on. Radio volume at 25 or higher.Set Condition:The amplifier detects that the output circuits are shorted together.Possible Causes(X202) AMPLIFIED RIGHT I/P SPEAKER (+) CIRCUIT SHORTED TO THE (X292) AMPLIFIED RIGHT I/P SPEAKER (-) CIRCUITAMPLIFIED RIGHT I/P SPEAKERAMPLIFIER1. CHECK FOR AN INTERMITTENT CONDITIONTurn the ignition on, then off, and then on again.With the scan tool, erase Amplifier DTCs.Turn the radio on.Turn the volume level to 25.With the scan tool, read Amplifier DTCs.Does the scan tool display active: B1469-CHANNEL 2 AUDIO SPEAKER OUTPUT CIRCUIT SHORTED TOGETHER?YesGo To 2NoThe condition that caused this symptom is currently not present. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.Perform the BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)2. CHECK THE OPERATION OF THE AMPLIFIED RIGHT I/P SPEAKERTurn the ignition off.Disconnect the Amplified Right I/P Speaker.Measure the resistance of the speaker between the two terminals.Is the resistance of the speaker less than 1 ohm?YesReplace the Amplified Right I/P Speaker in accordance with the service information.Perform the BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)NoGo To 33. CHECK THE (X202) AMPLIFIED RIGHT I/P SPEAKER (+) CIRCUIT, AND THE (X292) AMPLIFIED RIGHT I/P SPEAKER (-) CIRCUITS FOR A SHORT TOGETHER

Disconnect the Amplifier C2 harness connector.Measure the resistance between the (X202) Amplified Right I/P Speaker (+) circuit, and the (X292) Amplified Right I/P Speaker (-) circuit.Is the resistance below 10K ohms?YesRepair the (X202) Amplified Right I/P Speaker (+) circuit, and the (X292) Amplified Right I/P Speaker (-) circuit for a short together.Perform the BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)NoReplace the amplifier in accordance with the service information.Perform the BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
