Fuel Cut System (Highlander)

  1. Connect Toyota hand-held tester or scan tool to data link connector No. 3. See Figure. Hand-held tester or scan tool is used to read engine RPM. Start engine and warm engine to normal operating temperature.
  2. Ensure A/C is off. Gradually increase engine speed to 3500 RPM. Using stethoscope, check for fuel injector operating sound. Ensure when throttle lever is released, fuel injector stops operating momentarily and then resumes operating. Shut engine off. Remove hand-held tester or scan tool.
