When the fuel lid opener switch is pushed, a fuel lid opener switch signal is sent to the ECM. The ECM turns on the fuel lid opener relay, and the fuel lid lock with motor assembly opens the fuel lid. When the fuel lid is open, a fuel lid courtesy switch signal is output from the fuel lid lock with motor assembly.
Inspect the fuses for circuits related to this system before performing the following procedure.
Connect the GTS to the DLC3.
