The theft deterrent module controls the SECURITY indicator
lamp. The SECURITY indicator has several operation modes:
• | The SECURITY indicator turns ON for 5 seconds and then turns OFF. |
- | This mode occurs when you turn the ignition switch from the OFF
to one of the following positions: |
- | This action indicates that an ignition key has the correct resistor
pellet code. This also functions as a bulb inspection. The theft deterrent
system is in good operating condition. |
• | The SECURITY indicator turns ON for 1 minute and then turns OFF
while the engine is running. |
- | This action indicates that the theft deterrent module detects
one of the following key detection circuit malfunctions: |
• | A faulty resistor pellet |
• | A short to the battery or ground |
- | The theft deterrent module continues to monitor the key detection
circuit constantly after the engine starts. If the malfunction goes away within
1 minute of the malfunction detection, the SECURITY indicator turns OFF
and the PASS-Key® II will function as normal. |
- | The following actions occur if the malfunction ends within 1 minute
of detection: |
• | The SECURITY indicator turns OFF. |
• | The PASS-Key® II functions normally. |
• | The SECURITY indicator turns ON for 3 minutes. |
| The SECURITY indicator turns ON for 3 minutes when an ignition key with
the wrong resistor pellet code is used to start the engine. This indicates
that the 3-minute shut down mode is active. The shut down mode prevents
the vehicle from starting. |
• | The SECURITY indicator flashes once per second when you turn the
ignition switch from the OFF to the RUN position. |
- | The flashing continues for as long as the ignition switch remains
in the RUN position, without the 3-minute shut down. The engine will not crank
during this time. |
- | One or more of the following conditions exists: |
• | The resistor sensing contacts at the ignition lock cylinder are
open or shorted. |
• | The key detection circuit is open or shorted to the battery or
ground. |
• | The ignition key resistor pellet is faulty, damaged or missing. |
• | The SECURITY indicator flashes once per second with the engine
running. |
- | One or more of the following conditions exists: |
• | A new unprogrammed theft deterrent module is installed. The theft
deterrent module is unable to read the resistor pellet due to a circuit malfunction. |
• | The resistor sensing contacts at the ignition lock cylinder are
open or shorted. |
• | The key detection circuit is open or shorted to the battery or
ground. |
• | The ignition key resistor pellet is faulty or damaged. |
- | When you attempt to start the engine again, the engine will start.
The SECURITY indicator flashes during the ignition cycle while the fault is
present. This is called the fail-enable mode. The vehicle will not be
protected by the PASS-Key® II until the key detection circuit
malfunction is corrected. Since the fault occurred while the engine was
running, the system has already detected a valid resistor pellet code.
The theft deterrent module allows the engine to start until the vehicle
is serviced and the malfunction is corrected. |
