Hola estoy intentando siguir su problema. esta es hora punta y tenemos muchas preguntas.
Asegurarse que no hay otra alarma que no es de fabrica. En este caso deberia de haber otro modulo de control de alarma. Alarmas no de fabrica suelen tener un boton de deactivaccion (Valet Key) debajo de la console de instrumentos.
Si el pin 34 esta libre, el alarma deberia ser inactivo. Probabilmente se activo' cuando hizo los trabajos en el coche.
Uno de los pins connectados al ~BCM es el alarma.
La unica manera de deactivar este alarma es enviar un impulso al pin del alarma, descargandolo a terra.
Hay que poner una resistencia de 9KOhm en el medio , de otra forma el alarma no se deactiva.
Aqui la esplicaccion:
"Factory Alarm Disarm Wire (-): This vehicle will disarm with (-) negative through a 9000 ohm resistor, must use single pulse to disarm and a double pulse on this wire will also unlock.
Factory Alarm Disarm Wire Location: N/A"
La esplicacion termina con "Factory Alarm Disarm Wire Location: N/A", sin decir qual pin es el alarma.
yo se de otras fuentes que deveria de ser el pin 34. Por esperiencia personal puedo decir que el connector deveria de estar conectado all bloque de aranque.
El hilo deve de ser blanco y rojo o bien violeto y azul.
Si no se pone una resistencia de 9Kohms en el pin apropiado, el alarma no se quita.
No hay otra manera.

Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly.
A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.
Symptoms may include:
Causes A code P0300 may mean that one or more of the following has happened:
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open
