CAUTION / NOTICE / HINT
Tech Tips
After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.
-
Turn the power switch on (IG) and wait for 2 minutes or more.
PROCEDURE
-
CHECK DTC OUTPUT (ALL)
-
Connect the GTS to the DLC3.
-
Turn the power switch on (IG).
-
Check for DTCs of all systems by following the prompts on the GTS screen.
-
Check if DTCs are output.
