      Condition	Proceed to
      DTC is not output	A
      DTC is output	B

   B: REPAIR MULTIPLEX COMMUNICATION SYSTEM  (See HOW TO PROCEED WITH TROUBLESHOOTING )

   A: GO TO Next Step 

3. INSPECT IF SKID CONTROL ECU CONNECTOR IS SECURELY CONNECTED 
   1. Check the skid control ECU connector's connection.

      OK: 

      The connector is securely connected. 

   NG: CONNECT CONNECTOR TO ECU CORRECTLY  (See ELECTRONIC CIRCUIT INSPECTION PROCEDURE )

   OK: GO TO Next Step 

4. INSPECT BATTERY 
   1. Check the battery voltage.

      Standard voltage: 

      10 to 14 V 

   NG: INSPECT CHARGING SYSTEM  (See ON-VEHICLE INSPECTION )

   OK: GO TO Next Step 

5. INSPECT TRACTION OFF SWITCH 
   1. Remove the traction OFF switch.
   2. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      TESTER CONNECTION SPECIFIED CONDITION
      
      

      Tester Connection	Condition	Specified Condition
      3 - 4	Pressed	Below 1 Ω
      3 - 4	Not pressed	10 kΩ or higher

   NG: REPLACE TRACTION OFF SWITCH 

   OK: GO TO Next Step 

6. CHECK TRACTION OFF SWITCH (GROUND TERMINAL) 
   1. Disconnect the K43 switch connector.
   2. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      TESTER CONNECTION SPECIFIED CONDITION
      
      

      Tester Connection	Specified Condition
      K43-4 - Body ground	Below 1 Ω

   NG: REPAIR OR REPLACE HARNESS OR CONNECTOR (GROUND CIRCUIT) 

   OK: GO TO Next Step 

7. CHECK WIRE HARNESS (SKID CONTROL ECU - TRACTION OFF SWITCH) 
   1. Disconnect the A15 ECU connector.
   2. Disconnect the K43 switch connector.
   3. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      TESTER CONNECTION SPECIFIED CONDITION
      
      

      Tester Connection	Specified Condition
      A15-41 (CSW) - K43-3	Below 1 Ω
      A15-41 (CSW) - Body ground	10 kΩ or higher

   NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

   OK: GO TO Next Step 

8. INSPECT COMBINATION METER ASSEMBLY 
   1. Check the combination meter (see INITIALIZATION ).

      HINT:

      If troubleshooting has been carried out according to the "PROBLEM SYMPTOMS TABLE ", refer back to the table and proceed to the next step before replacing the part.

   NG: REPLACE COMBINATION METER ASSEMBLY  (See REMOVAL )

   OK: REPLACE SKID CONTROL ECU (See  REMOVAL   )
