Circuit Description

WARNING: This page is about a different car, the 2007 Saturn Ion 3 and 2007 Saturn Ion 2. However, it is still accessible from the selected car via links, so may be relevant.

The body control module (BCM) controls the automatic transmission (A/T) shift lock control solenoid by providing battery voltage to the solenoid. The BCM utilizes a smart driver to control the voltage supplied to the A/T shift lock control solenoid. The smart driver monitors the voltage and current flow of the control circuit. DTC B2709 will set when the BCM detects an open circuit during the shift lock control solenoid operation.
