Unable to Engage Park
The TCM commands the park pawl to engage but the position sensors do not confirm engagement — typical for shift-by-wire systems where the park actuator (motor or solenoid driving the pawl) is faulty, the cable is broken, or the pawl is jammed against a tooth and cannot drop in.
