Diagnosis System
DIAGNOSIS SYSTEM DESCRIPTION When troubleshooting a vehicle with the diagnosis system, the only difference from the usual troubleshooting procedure is connecting the GTS to the vehicle and reading various data output from the vehicle's skid control ECU (brake actuator assembly)...
Dtc Check / Clear
DTC CHECK / CLEAR DTC CHECK (a) Operate the GTS to read the DTCs. Chassis > Brake > Trouble Codes (b) Check the details of the DTCs. NOTICE:
Make sure to clear the DTCs after repair...

Fuel-Filler Lid and Cap
WARNING
When removing the fuel-filler cap, loosen the cap slightly and wait for any hissing to stop, then remove it
Fuel spray is dangerous. Fuel can burn skin and eyes and cause illness if ingested. Fuel spray is released when there is pressure in the fuel tank and the fuel-filler cap is removed too quickly.
