Defect Code 5 - 26

Defect Codes 5-26:

*D* Defect code memory: 5-26; One or Several Defect Codes between 5 and 26 Stored (incorrect polarity):

Explanation: Motor or potentiometer poles have been interchanged.

Note: The connectors at the adjustment buttons may also be interchanged. Check switch logic with diagnostic program.

Troubleshooting: Check motor polarity: Activate drives with diagnostic program; if the polarity is incorrect, the corresponding drive runs in the opposite direction. Correct polarity in this case. If the defect is not recurred, check the potentiometer polarity: For this purpose, activate drives and observe the
voltage value of the corresponding motor during activation (indicated on screen): The voltage value must increase in the following movement directions: Seat height up, backrest forward, tilt up, seat movement forward, mirror vertically up, mirror horizontally to right. Correct polarity of corresponding potentiometer.
