VC Output Circuit: Procedure

1. Check that the Malfunction Indicator Lamp (MIL) illuminates when turning the power switch on (IG).

   OK

   MIL lights up.

NG → See step   2 

OK → See step   12 

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Turn the Techstream on.
4. Check the communication between the Techstream and hybrid vehicle control ECU.
