Defect Code 49
Defect Code 49:
Malfunction: 49 Failure of Individual Adjustment Functions:
Possible cause: Switch, drive, potentiometer, wires
Attention: The control unit must not be in diagnostic mode. Excessive dirt build-up or icing can cause temporary difficulty in movement of the mirror motor drives. Further more, a temporary mechanical blocking (e.g. foreign object in area of adjustment kinematics) may be the cause of the defect code being entered in the defect code memory. Check defects which have occurred in this way (check mechanics for stiffness/blocking) and clear defect code memory.
Troubleshooting: Is movement of the faulty drive possible via the adjustment switches?
Yes: Read out defect code memory and check corresponding defect, clear defect code memory.
No: Activate corresponding drive(s) in diagnostic program. Is the relevant drive operable?
Yes: Check adjustment switch in diagnostic program. If adjustment switch is OK., check wires from adjustment switch to control unit in accordance with schematic and repair if necessary.
No: Check all wires from the motor drive in accordance with the schematic and repair if necessary. If wires are OK. and defect is still not rectified, renew corresponding motor and perform test run.
