How To Proceed With Troubleshooting

HINT: 

*: Use the Techstream.

1. VEHICLE BROUGHT TO WORKSHOP 

   NEXT: Go to next step 

2. INSPECT AUXILIARY BATTERY VOLTAGE 

   Standard voltage

   11 to 14 V

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

   NEXT: Go to next step 

3. INSPECT COMMUNICATION FUNCTION OF CAN COMMUNICATION SYSTEM* 
   1. Using the Techstream, inspect the CAN communication function to ensure there are no malfunctions in the communication system.

      Result	Proceed to
      No DTCs (CAN communication system) output	A
      DTCs (CAN communication system) output	B

      HINT: 

      The skid control ECU sends the signals of each warning light to CAN communication.
