The control unit must run the automatic force search procedure (refer to the “Learning of the door opening and
closing positions” paragraph). If the courtesy light ashes also during the manoeuvre, it means that a procedure
is under way to detect the critical points of the manoeuvre.
If it ashes synchronously with the warning light, there is an anomaly (refer to “Table 13”).
