(4) The fault code will flash in the following sequence:
First, a "Check Engine" (yellow) lamp will flash. There will be a short 1- or 2-second pause after
which the number of the recorded fault code will flash in the "Engine Stop" (red) lamp. There will
be a 1- or 2-second pause between each number. When the number has finished flashing in the
red lamp, the yellow lamp will appear again. The fault code will repeat in the same sequence.
The lamps flash each fault code 3 times before advancing to the next code. To skip to the next
fault code, move the Engine Codes Switch momentarily to the UP position. You can go back to
the previous fault code by momentarily moving the Engine Codes Switch to the DOWN position.
If only one fault is recorded, the QSB control system will continuously display the same fault code
when the Engine Codes Switch is moved to either the UP or DOWN position.
(5) See engine manufacture's manual for code meanings.
