PRECAUTIONS WHEN USING GTS
When using the GTS with the power switch off to troubleshoot:
Connect the GTS to the vehicle, and turn a courtesy light switch on and off at 1.5 second intervals until communication between the GTS and vehicle begins.
After all DTCs are cleared, check if the malfunction occurs again 6 seconds after the power switch is turned to on (IG).
