## NHTSA's summary

?RETRACTABLE HARDTOP STATUS REQUEST SUPPLEMENT. INFORMATION Documents have been developed showing the known correct statuses for all hall sensors and micro switches used to operate the retractable hard top \(RHT\). This document is intended to act as a supplement to the diagnostic information available in ISTA. Comparing these statuses to the actual statuses of a vehicle with a functional problem may assist in narrowing down which sensor/switch is contributing to the functional problem. For E93, the status request may be found by connecting the car to ISTA and selecting: Control module functions/CTM Convertible top module/Diagnosis Requests ?Sensors/Switches For F33/F83, the statuses should be checked using the applicable test plan as instructed in attachment B54 09 07 F33 F83 RHT Status.pdf.
