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 B2707 will set when the BCM detects a short to ground, during the shift lock control solenoid operation.
