DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Pinpoint Tests: Notes
DTCs B1319:11, B1319:15
Refer to Shift Interlock for schematic and connector information.
Normal Operation and Fault Conditions
The BCM provides power to the Brake Shift Interlock Actuator (BSIA). When the BCM receives a brake pedal applied input, voltage is applied to the brake shift interlock actuator. When the actuator is energized, the plunger is pulled inward allowing the selector lever to move from the park position.
