Technical Background
A fault in the potentiometer in the cover flap motors sends an implausible signal to the convertible top control unit. The convertible top operation control
unit stops the top operation when the cover flaps are fully open.
Production Solution
In preparation.
Service
1. Check and/or adjust the push rods of the flap motors using Guided Fault Finding. Go to address word 26-Convertible top operation J256, and view
measuring value block 8. MVB 8 of the electric roof operation shows the threshold and actual values for the potentiometers. The shift points of the
left/right flap sender are shown in open condition:
-
Field 01: Switch threshold-Left Top Flap Sensor G596 (maximum allowable value when flap is open).
-
Field 02: Actual value-Left Top Flap Sensor G596.
-
Field 03: Switch threshold-Right Top Flap Sensor G597 (maximum allowable value when flap is open).
-
Field 04: Actual value-Right Top Flap Sensor G597.
2. Adjust the push rods of the flap motors while viewing the MVB. The actual value must be less than the switch threshold value after the adjustment.
If the actual value is greater than the threshold value, an implausible condition can result.
