Encoding/Programming Notes
After replacement, the convertible top module (CVM) must be re-encoded.
Window Adjustments
The windows on the E88 don’t have to be initialized, but they do need to be adjusted to
the body to prevent rattles, wind noises and vibrations as well as water leaks.
Note: Special tools are needed to perform the window adjustment procedure.
Please refer to the repair instructions in TIS for the most up to date
window adjustment information and a list of special tools needed to
perform the procedure.
Positions for the Convertible Top Diagnosis
The automatic convertible top has 10 sensors in all:
• 8 Hall sensors
• 1 microswitch
• 1 incremental sensor
These sensors detect the different positions of the convertible top as it is opening and
closing. In order to pinpoint faults, the system must be aware of which intermediate posi-
tion the convertible top is in. This helps in diagnosing the system by pinpointing the faulty
component or verifying the fault code present.
Note: The following pages show the diagnostic equipment in Control Module
Functions, to monitor sensor position and activity of the convertible top
as it is operated and stopped in pre-determined positions. Pay close
attention to the terminology and the proper position of the top as you
perform diagnosis.
