INSPECTION PROCEDURE

NOTICE:

Inspect the fuses for circuits related to this system before performing the following inspection procedure.

1. Check for optional components.
   

   1. Check that optional components (including associated wiring) which generate radio waves are not installed.
      

      Result

      Result	Proceed to
      Optional components (including associated wiring) are installed.	A
      Optional components (including associated wiring) are not installed.	B

      HINT:

      1. Electrical noise from radio waves generated by optional components or the wiring for those components may affect MOST communication.
         
      2. This DTC may be stored when a MOST communication error occurs due to electrical noise.
         

1. Remove optional components (including associated wiring).
   

   NOTICE:

   Do not remove optional components or associated wiring without the permission of the customer.

1. Clear the DTCs (Click here).
   

1. Recheck for DTCs and check if the same DTC is output again (Click here).
   

   OK:

   No DTCs are output.
   

1. Disconnect the stereo component amplifier assembly connector.
   

2. Measure the resistance according to the value(s) in the table below.
   

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   F74-3 (GND) - Body ground	Always	Below 1 Ω
   F74-18 (GND2) - Body ground	Always	Below 1 Ω

3. Measure the voltage according to the value(s) in the table below.
   

   Standard Voltage:

   Tester Connection	Condition	Specified Condition
   F74-1 (+B) - F74-3 (GND)	Always	11 to 14 V
   F74-16 (+B2) - F74-3 (GND)	Always	11 to 14 V

1. Disconnect the F84 multi-media module receiver assembly connector.
   

2. Disconnect the F85 stereo component amplifier assembly connector.
   

3. Measure the resistance according to the value(s) in the table below.
   

   Standard Resistance:

   F84-4 (SLDI) - F85-7 (SLDO)	Always	Below 1 Ω
   F84-5 (MO+) - F85-2 (MI+)	Always	Below 1 Ω
   F84-6 (MO-) - F85-3 (MI-)	Always	Below 1 Ω
   F84-7 (SLDO) - F85-4 (SLDI)	Always	Below 1 Ω
   F84-2 (MI+) - Body ground	Always	10 kΩ or higher
   F84-3 (MI-) - Body ground	Always	10 kΩ or higher
   F84-4 (SLDI) - Body ground	Always	10 kΩ or higher
   F84-5 (MO+) - Body ground	Always	10 kΩ or higher
   F84-6 (MO-) - Body ground	Always	10 kΩ or higher
   F84-7 (SLDO) - Body ground	Always	10 kΩ or higher

1. Replace the stereo component amplifier assembly with a new or normally functioning one (Click here).
   

1. Clear the DTCs (Click here).
   

1. Recheck for DTCs and check if the same DTC is output again (Click here).
   

   OK:

   No DTCs are output
   

1. Disconnect the F84 multi-media module receiver assembly connector.
   

2. Disconnect the F85 stereo component amplifier assembly connector.
   

3. Disconnect the L56 television assembly connector.
   

4. Measure the resistance according to the value(s) in the table below.
