INSPECTION PROCEDURE

PROCEDURE

1. INSPECT FUSE (CRT, GAUGE NO. 1, RADIO NO. 2)

   
   

   1. Disconnect the CRT fuse from the engine room relay block and junction block.

      
      

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

         Standard resistance
         Tester Connection Condition Specified Condition CRT fuse Always Below 1 Ω

   2. Remove the RADIO NO. 2 fuse from the driver side junction block assembly.

      
      

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

         Standard resistance
         Tester Connection Condition Specified Condition RADIO NO. 2 fuse Always Below 1 Ω

   3. Remove the GAUGE NO. 1 fuse from the driver side junction block assembly.

      
      

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

         Standard resistance
         Tester Connection Condition Specified Condition GAUGE NO. 1 fuse Always Below 1 Ω

   
   

   NG

   REPLACE FUSE

   OK

2. CHECK HARNESS AND CONNECTOR (TELEVISION CAMERA ECU - BATTERY AND BODY GROUND)

   
   

   1. 

      Disconnect television camera ECU connector N16.

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

      Standard resistance
      Tester Connection Condition Specified Condition N16-8 (GND1) - 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 N16-1 (+B) - Body ground Always 11 to 14 V N16-3 (IG) - Body ground Ignition switch on (IG) 11 to 14 V N16-4 (ACC) - Body ground Ignition switch on (ACC) 11 to 14 V

   
   

   NG

   REPAIR OR REPLACE HARNESS OR CONNECTOR

   OK
