B2707

DTC B2707





Circuit Description
The Body Control Module (BCM) controls the automatic transmission shift lock control solenoid. Battery positive voltage is supplied to the automatic transmission shift lock control solenoid. The BCM controls the automatic transmission shift lock control solenoid ground circuit. When the driver pressed the brake pedal the BCM removes the ground for the automatic transmission shift lock control solenoid. The solenoid de-energizes and releases the mechanical lock allowing the shift lever to be moved out of the PARK position.

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

Conditions for Setting the DTC
The automatic transmission shift lock control is open or shorted to ground for a minimum of 5 seconds.

Action Taken When the DTC Sets
^ If the shift lock control circuit is open, the automatic transmission shift lock control solenoid will be inoperative.
^ If the shift lock control circuit is shorted to ground, the automatic transmission shift lock control solenoid will always be engaged with the ignition ON.

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

Diagnostic Aids
Perform the tests while wiggling the wires and connectors. This may often cause an intermittent malfunction to appear.

Test Description
The number(s) below refer to the step number(s) 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 the ignition 1 voltage circuit of the automatic transmission shift lock control solenoid.
4. Verifies that the BCM is providing a ground to the automatic transmission shift lock control solenoid.
5. Tests if a ground is constantly being applied to the automatic transmission shift lock control solenoid.
