Convertible system signal specification

General 

The convertible system only functions when the ignition is on.

Control module terminals A1- A30 and C1- C16 are positioned on adapter 9813194 .

Control module terminals B1- B8 and D1- D14 are positioned on adapter 9511496 .

See the convertible system wiring diagram for the relevant model year. See ACTIVE BODYWORKS .

U=	DC voltage in volts (V)	Ubat1 =	Battery voltage 1 (V)
Ubat2 =	Battery voltage 2 (V)	Usig =	Signal voltage (V)

Connector A; A1- A30 

All values specified below are between the terminals in column 1 and a ground point in the car or in adapter wiring 9511496 terminal #5 (connection of an additional breakout box is required in the latter case).

Control module terminals A1- A30 correspond to terminals #1- #30 on the breakout box.
