J5 CHECK THE ELECTRICAL CONNECTORS

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.

Ignition OFF. Disconnect Moveable Roof Control Module A (MRCMA) C4830. Disconnect Moveable Roof Control Module B (MRCMB) C4831. Using a good light source, inspect each connector for the following:

corrosion - install new connector or terminal and clean the module pins damaged or bent pins - install new terminals or pins pushed-out pins - install new pins as necessary

Using a suitable mating terminal, check the following connector terminals for deformed or enlarged contacts:

C4830-9 C4830-10 C4831-9 C4831-10

Are both connectors free of corrosion, pushed-out pins and deformed or enlarged contacts?

Yes

The system is operating correctly at this time. The DTC may have been set due to high network traffic, a loose connector, a corroded connector or an intermittent fault condition. ADDRESS the root cause of any connector or pin issues.

No

REPAIR the affected connector. Refer to Wiring Diagrams Cell 5 for schematic and connector information.

Rear Window Down Feedback Signal Faults

Refer to Wiring Diagrams Cell 100 for schematic and connector information.

Normal Operation and Fault Conditions

After receiving a "window drop" message from the Moveable Roof Control Module A (MRCMA), the BCMB sends a global open request to the 4 window smart motors. Once the windows have fully lowered, the rear window smart motors send a ground signal to the BCMB indicating they are in the full down position. The BCMB then sends a "window down" message to the Moveable Roof Control Module A (MRCMA) and convertible top operation continues. When there is a fault on the circuit between the BCMB and the smart motors or when there is a failure of the BCMB or smart motors, the rear windows do not operate when the convertible top is open or closed which prevents convertible top operation. For additional information on window operation, REFER to: Glass, Frames and Mechanisms - System Operation and Component Description (501-11 Glass, Frames and Mechanisms, Description and Operation).
