Test 4

Tests 4 and 5 check the fuel level and fuel flow circuits. Switch the ENGLISH/METRIC switch to ENGLISH. The trip computer will display the condition of the range indicator lights. If a failure of the fuel level sensor input is detected, the letters "CO" will display for an open circuit. The letters "CS" will display for a short circuit. If there are no failures detected, the fuel level will be displayed in liters.
