Diagnosis
The diagnostic functions of the Soft-top module IV are to a large degree identical with those on the E46. However, fewer signals are analyzed on the E85 than on the E46 because there are fewer components on the E85.
Soft-Top Module 4 Internal Check
The internal functions of the Soft-top module 4 are checked under the following circumstances
- When the power is switched on
- When terminal R is ON
- Before the soft-top is raised/lowered
If a system fault is detected, movement of the soft-top is stopped immediately. The fault detected is recorded in the fault memory of the Soft-top module 4. If the nature of the fault allows, the soft-top can be moved to the nearest safe parked position using one of the soft-top control buttons.
