How To Proceed With Troubleshooting

HINT:

• Use the following procedures to troubleshoot the variable gear ratio steering system.
• *: Use the Intelligent tester or Techstream.

1. VEHICLE BROUGHT TO WORKSHOP 
2. INSPECT BATTERY VOLTAGE 

   Standard voltage: 11 to 14 V 

   If the voltage is below 11V, recharge or replace the battery before proceeding.

3. INSPECT ELECTRIC POWER CONTROL SYSTEM* 
   1. Using the Intelligent tester or Techstream, check the electric power control system's load control history (see OPERATION CHECK ).
4. CHECK CAN COMMUNICATION SYSTEM* 
   1. Check for DTCs (see CAN COMMUNICATION SYSTEM ).

      Result 

      CAN COMMUNICATION SYSTEM
      
      

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

   B: GO TO  CAN COMMUNICATION SYSTEM 

   A: GO TO NEXT STEP 

5. CHECK DTC* 
   1. Check for DTCs (see DTC CHECK/CLEAR  ).
   2. Clear the DTCs (see DTC CHECK/CLEAR  ).
   3. Recheck for DTCs (see DTC CHECK/CLEAR  ).
      1. Simulate the malfunction and check if the DTCs are output again (see DTC CHECK/CLEAR  ).
