Press a button. If the error signal doesn't disappear, the control
should be replaced
If the cam shaft is rotating, wait until it reaches the "service position",
and the error signal will disappear. If the error signal does not disappear
and the cam shaft keeps rotating, check that the optical sensor is not
out of its seat (fig. 9, C). If the cam shaft is not rotating, check that the
connecting cables between the engine and the control are not damaged
(fig. 9, A, B).
