STEP 3. Voltage measurement at ETACS-ECU connector (IGS line)
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Turn the engine switch from "OFF" position to "ON" position.
(3) Measure the voltage between the ETACS-ECU connector (IGS line) and the body ground.OK: The voltage should measure approximately 12 volts (battery positive voltage).
(4) Turn the engine switch from "ON" position to "OFF" position.
(5) Measure the voltage between the ETACS-ECU connector (IGS line) and the body ground.OK: 1 volt or less
Is the check result normal?
