3.

CHECK BATTERY VOLTAGE

(a) Check the battery voltage.

Standard Voltage:

11 to 14 V

HINT:

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

NEXT

4.

CONNECT TECHSTREAM TO DLC3*

HINT:

If the display indicates a communication fault in the Techstream, inspect the DLC3.

When any CAN communication system DTCs are output, perform troubleshooting on the CAN communication system first.

NEXT

5.

CHECK CAN COMMUNICATION SYSTEM*

(a) Use the Techstream to check if the CAN communication system is functioning normally.

CAN Bus Check

HINT:

  • Refer to CAN Bus Check for the CAN communication system.
