CONTENT THEFT DETERRENT (CTD) DESCRIPTION AND OPERATION The CTD system, when armed, is designed to deter vehicle content theft by pulsing the horns and exterior lamps for approximately 2 minutes when an unauthorized vehicle entry is detected. However, the CTD system does not affect engine starting. An unauthorized entry can be any of the following with the CTD system armed:
The components of the system are:
IMPORTANT The CTD system can be armed with the windows or sunroof open. Arming the CTD System Use the following procedure in order to arm the system:
CTD Circuit Description The following is a description of each component used in the CTD system: Body Control Module (BCM) The CTD system is an internal function of the Body Control Module (BCM) which utilizes class 2 serial data and various switch input information to perform CTD functions. When the BCM detects an unauthorized entry, it activates the horns and exterior lamps. When the BCM detects an unauthorized entry, the BCM enters the alarm mode. The BCM activates the horns and exterior lamps for 2 minutes . This is followed by a three minute time-out with the horn no longer active. If no new intrusions are detected after the time-out, the horn is not active. The system must be disarmed or the intrusion condition removed after the time-out for the system to exit alarm mode. Door Ajar Switches The CTD system uses the door ajar switches in the door jambs as one method to activate the alarm. The body control module (BCM) monitors all door ajar switches via a discrete input from each door ajar switch, including the rear compartment. If the BCM receives a ground signal from a door ajar switch when the CTD system is armed, the BCM activates the alarm. Inputs The BCM monitors the following inputs:
Outputs The BCM controls the following:
Here’s how you can bypass the sensor.
Go buy a 2.2k (2200 ohm) ohm resistor at an electronics store. Go to radio shack and just get one as close to that as you can. Remove the covers on the steering column and locate three small wires at the lock cylinder. Cut the yellow wire and the orange/black wire. Solder the resistor between those wires. Tape it up and put the covers back on and follow this relearn procedure. If this doesn't work you have a wiring problem in the steering column.
The vehicle learns the Passlock™ Sensor Data Code and/or password XXXXX the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
