If you look on page 54B-345 of the service manual, all that's in the circuit the 10A fuse (#14 as citm said), the ETACS ECU, the wiring, and the sockets/bulbs. Here's the steps to take:
Check at ETACS-ECU connector C-119 in order to check the power supply circuit to the ETACS-ECU (battery power supply).
(1) Disconnect ETACS-ECU connector C-119, and measure at the junction block side.
(2) Measure the voltage between terminal 11 and ground.
• The measured value should be approximately 12 volts (battery positive voltage).
If you have battery voltage there, it's your ETACS ECU. If you don't have voltage there, then your problem would most likely be in the wiring between the fuse and the ETACS ECU. Since both your hazards and turn signals aren't working, it's less likely that either of the switches are bad, or the wiring to and/or from the switches...it's probably part of the shared wiring...
