B2707

DTC B2707

Test 1-9:

Circuit Description
The body control module (BCM) controls the automatic transmission shift lock control solenoid by providing battery voltage to the solenoid. The BCM utilizes a smart driver to control the voltage supplied to the automatic transmission shift lock control solenoid. The smart driver monitors the voltage and current flow of the control circuit. DTC B2707 will set when the body control module (BCM) detects a short to ground during the shift lock control solenoid operation.

Conditions for Running the DTC
^ The ignition switch is in the ON position.
^ The brake pedal is depressed.
^ 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 inoperative. The shift lever will not shift out of PARK position with the brake pedal depressed.
^ Perform the tests while wiggling the wires and connectors. This may often cause an intermittent malfunction to appear.

Test Description
The numbers 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.
3. Tests for voltage at controlled voltage supply circuit of the automatic transmission shift lock control solenoid.
