Switch Input Module A (SIMA)

The SIMA is located at the top center of the instrument panel and contains an array of up to six switches that are a direct input to the SIMA. These switch inputs control the following outputs (if equipped):

• Hazard Signal
• Front E-Locker
• Rear E-Locker
• Sway Bar Disconnect
• Off Road Turn Assist
• Roll Stability Control

The SIMA is serviced as a complete unit.

SIMA power is provided by the BCM. The FD-CAN provides signal input messages to the various components including the sway bar disconnect module, all terrain control module and more.
