How To Proceed With Troubleshooting

HINT:

*: 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 COMMUNICATION FUNCTION OF CAN COMMUNICATION SYSTEM* 
   1. Using the Intelligent tester or Techstream, inspect the CAN communication function to ensure there are no malfunctions in the communication system
