Inspection Procedure

1. Disconnect the stereo component amplifier S13 and S14 connectors.
2. Measure the resistance according to the values in BATTERY - STEREO COMPONENT AMPLIFIER (RESISTANCE)  .

   Standard resistance 

   BATTERY - STEREO COMPONENT AMPLIFIER (RESISTANCE)
   
   

   Tester Connection	Condition	Specified Condition
   GND (S13-16) - Body ground	Always	Below 1 Ω
   GND2 (S13-15) - Body ground	Always	Below 1 Ω

3. Measure the voltage according to the values in BATTERY - STEREO COMPONENT AMPLIFIER (VOLTAGE)  .
   BATTERY - STEREO COMPONENT AMPLIFIER (VOLTAGE)
   
   

   Tester Connection	Condition	Specified Condition
   B+ (S13-1) - GND (S13-15)	Always	10 to 14 V
   B2+ (S13-10) - GND (S13-15)	Always	10 to 14 V
   ACC (S14-12) - GND (S13-15)	Ignition SW ACC	10 to 14 V
