ASC SYSTEM FAIL-SAFE CHART


  1. ASC System


    1. The stereo component equalizer assembly stores DTCs and freeze frame data and stops sound output if it detects any of the following abnormalities.

      Item Abnormality Detection Condition Fail-safe Control DTC Output Return Condition
      CAN communication malfunction Communication with ECM interrupted Sound output is stopped

      U0100

      (Freeze frame data stored)

      		 Signals are received normally and communication returns to normal
      Communication with brake actuator assembly (skid control ECU) interrupted Sound output is stopped

      U0122

      (Freeze frame data stored)

      		 Signals are received normally and communication returns to normal
      Communication with main body ECU (multiplex network body ECU) interrupted Sound output is stopped

      U0142

      (Freeze frame data stored)

      		 Signals are received normally and communication returns to normal
      Abnormal vehicle speed signal sent from brake actuator assembly (skid control ECU) Sound output is stopped

      U0418

      (Freeze frame data stored)

      		 Signals are received normally and communication returns to normal

      • Abnormal timestamp signal from main body ECU (multiplex network body ECU)

      • Abnormal trip count signal from main body ECU (multiplex network body ECU)

      		 Not applicable

      U0422

      (Freeze frame data stored)

      		 Signals are received normally and communication returns to normal
      Speaker connection malfunction When vehicle sound switch volume is set to medium or higher and sounds are being output, an open is detected for 0.15 seconds or more Sound output is stopped

      B1360

      (Freeze frame data stored)

      		 When vehicle sound switch volume is set to medium or higher and sounds are being output, an open is not detected for 0.15 seconds or more
      Switch connection malfunction The VSLI terminal voltage to the CPU of the stereo compartment equalizer assembly is 4.5 V or more Sound output is stopped

      B1361

      (Freeze frame data stored)

      		 The VSLI terminal voltage to the CPU of the stereo compartment equalizer assembly is less than 4.0 V and connection returns to normal
      ECU internal malfunction

      • The IG power source voltage to the CPU of the stereo component equalizer assembly is 0.5 V or less

      • Sound output IC malfunction

      		 Sound output is stopped

      B1362

      (Freeze frame data stored)

      		 The IG power source voltage to the CPU of the stereo component equalizer assembly is 2.2 V or more and the malfunctioning part returns to normal
