When armed, the CTD system is designed to deter vehicle
theft. The system deters theft by pulsing the horns and the exterior lights
when the system detects an unauthorized vehicle entry. An unauthorized
entry may be any one of the following cases:
• | Forced entry into the rear compartment |
• | When any door is opened. |
The remote function actuator (RFA) module controls all of the alarm
functions. When the RFA detects an unauthorized entry, the RFA applies ground
to the horn relay and to the lamp control module (LCM) once per second.
Ground is applied for approximately 3 minutes, or until the RFA
receives a valid input to disarm. The RFA has the following 5 basic
modes:
| The CTD is disarmed until the RFA detects all of the following conditions: |
- | The ignition switch is turned to the lock position. |
- | The doors are locked by either the power door lock switch or the
keyless entry transmitter (key fob). If all of the doors are closed and the
key fob is used in order to lock the doors, the RFA enters the delayed
mode. |
| The CTD is in standby when the RFA detects the above conditions. The
RFA grounds CKT 264 (DK GRN) once per second. This action flashes
the SECURITY indicator. When the RFA detects that all of the doors are
closed, the system enters delayed mode. |
| The CTD system is in delay mode for 30 seconds. The RFA grounds
CKT 264 (DK GRN) continuously. This action illuminates the SECURITY
indicator. After 30 seconds, the system enters armed mode. |
| When the CTD system is armed, the system monitors all of the inputs
for an unauthorized forced entry. The RFA stops grounding CKT 264
(DK GRN). This action turns the SECURITY indicator off. If the RFA detects
a forced entry, the system enters alarm mode. |
| The CTD system detects a forced entry while in armed mode. The RFA grounds
the horn relay CKT 28 (BLK/WHT) and the exterior lights control enable
input CKT 624 (BLK/WHT) to the LCM. The RFA grounds
once per second for approximately 3 minutes, or until the RFA receives
a valid input to disarm. After 3 minutes, the CTD returns to the
armed mode. |
If the RFA receives a door unlock request during the arming sequence,
the CTD system does not enter the armed mode. The RFA stops grounding CKT 264
(DK GRN). The SECURITY indicator turns off. At this point, in order to
enter the armed mode, you must repeat the arming sequence. The CTD system
can enter the armed mode with the windows open.
Arming the System
Use the following procedure in order to arm the CTD system:
- Close all of the windows.
- Place the shift lever in PARK.
- Turn the ignition switch to LOCK. Remove the key.
- Open any door.
- Lock the doors with the power door lock switch or the lock button
on the key fob.
- Close all of the doors.
After approximately 30 seconds, the SECURITY indicator turns
off. The system is now armed. Any forced entry detected activates the alarm.
In order to disarm the CTD system, refer to Disarming the System.
Locking the Vehicle Without Arming the System
Use one of the following procedures in order to lock the vehicle without
arming the system:
- Manual locking
1.1. | Use the manual door lock knobs in order to lock the vehicle. |
1.2. | Close all of the doors. |
- Key locking
2.1. | Close all of the doors. |
2.2. | Use the key or the power door lock switch in order to lock the
door. In order to use this method, the doors must be closed prior to locking. |
Disarming the System (Standby, Delayed, and Armed Modes)
In order to disarm the system in the standby mode (the SECURITY indicator
is flashing and the doors are open) complete either of the following steps:
• | Press the power door lock switch to the UNLOCK position. |
• | Press the UNLOCK button on the key fob. |
In order to disarm the system in the delayed or the armed mode, complete
either of the following steps:
• | Use the key in order to unlock either front door. |
• | Press the UNLOCK button on the key fob. |
Deactivating the Alarm (Horns Sounding and Lights Flashing)
In order to deactivate the system in the alarm mode (horns sounding
intermittently and headlights flashing), complete either of the following
steps:
• | Use the key in order to unlock either front door. |
• | Press the UNLOCK button on the key fob. |
SECURITY Indicator Operation
The RFA illuminates the SECURITY indicator . The indicator is located
in the instrument cluster (BUICK) or in the remote indicator bank (Oldsmobile)
by grounding CKT 264 (DK GRN).
