No  

The 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 BODY VERIFICATION TEST - VER 1 .  

2) CHECK FOR VOLTAGE ON THE (X201) AMPLIFIED LEFT I/P SPEAKER (+) CIRCUIT

Possible Causes
