Initialization

FULL OPEN RETRACTABLE ROOF INITIALIZATION PROCEDURE

NOTE: There are two initialization procedures that may be used when servicing the full open retractable roof. The Diagnostic Scan Tool procedure requires the use of the diagnostic scan tool and a dedicated routine that is used to initialize the full open retractable roof following replacement or reprogramming of the SUNRoof (SUNR) electronic control unit. The Manual procedure is used following service of any of the retractable roof hardware components.

Limits

Temperature

The temperature must be between 5°C (41°F) to 45°C (113°F) for initialization to be performed, Outside of this temperature range an initialization will not start and if requested by a diagnostics scan tool, the Electronic Control Unit (ECU), (sometimes referred to as the Power Top Control Module) will send the proper reject code.
