approximate 3.3VP-P square wave can be confirmed at each NG terminal, there are no problems with DIR (PCM9211) and the PWM PWM waveform (square wave) is disrupted. Fault in IC70 (TAS5142). CONTROLLER (TAS5558). Replace the IC70 (TAS5142). If the fault still occurs after replacement, check "2.1.A". OK 2.1
