NG:  Go to step  7

OK: Go to Next Step 

1. Reconnect the skid control ECU connector.
2. Perform Active Test of the combination meter (meter CPU) using Techstream (See DATA LIST / ACTIVE TEST ).

   OK: The TRAC OFF indicator light turns on or off in accordance with Techstream. 

   HINT:

   If troubleshooting has been carried out according to the PROBLEM SYMPTOMS TABLE , refer back to the table and proceed to the next step before replacing the part.
