Test Function No. 6 - Tank Content Values and Display Value

This function is locked and needs to be unlocked via the procedure in Function Test No. 19. The following data can be scrolled through using the trip reset button. The first display line shows the tank content from the left and right fuel tank level sensors and the overall tank content. The second display line shows the average overall tank content and the value after 'PHASE' relates to the procedure used to calculate the content value.
- 'TNK: 29.5/34.2/63.7L' - this shows content in left half of tank / content in right half of tank / momentary overall tank content.
- 'TNKANZ: 60.2L PHASE1' - average tank content and calculation method. The PHASE shows the calculation method as defined below.
  - PHASE1 = Normal calculation procedure using both sensors with no errors.
  - PHASE2 = In the case of a tank level sensor failure, the calculation is performed using the injector PWM signal available on the CAN.
  - PHASE3 = If a sensor failure has occurred and the injector PWM signal is not available, the fuel level gauge will read empty and the low fuel warning lamp will be illuminated.
