B2707

DTC B2707

Circuit Description
The Body Control Module (BCM) controls the automatic transmission shift lock control solenoid by providing a controlled ground to the automatic transmission shift lock control solenoid. The BCM utilizes a smart driver to monitor the voltage and current flow of the automatic transmission shift lock control solenoid control circuit. DTC B2707 will set when the BCM detects a short to ground when the solenoid is in the OFF state.

Conditions for Running the DTC
^ The ignition switch is in the ON position.
^ The brake pedal is released.
^ The transmission the PARK position.

Conditions for Setting the DTC
The BCM detects the shift lock control solenoid control circuit is grounded for a minimum of 1 second.

Action Taken When the DTC Sets
The BCM disables shift lock control solenoid operation until the next key cycle.

Conditions for Clearing the DTC
^ A current DTC B2707 will clear when the malfunction is no longer present and the ignition switch is cycled.
^ All BCM history codes will clear after 100 ignition cycles with no current codes active during the 100 ignition cycles.

Diagnostic Aids
^ If the A/T shift lock control circuit is shorted to ground, the automatic transmission shift lock control solenoid will be energized. The shift lever will not shift out of PARK position with the brake pedal pressed.
^ Perform the tests while wiggling the wires and connectors. This may often cause an intermittent malfunction to appear. Refer to Testing for Intermittent and Poor Connections.

Test Description
The numbers below refer to the step numbers on the diagnostic table.
2. Listen for an audible click when the automatic transmission shift lock control solenoid operates. Command both the ON and OFF states. Repeat the commands as necessary.
4. Tests for ground at the control circuit of the automatic transmission shift lock control solenoid.
