Theft Deterrent - Unprogrammed Module

If you replace a theft deterrent mode, program it to accept the resistance value of the existing vehicle keys in order to allow correct operation of PASS-key II.

A new service replacement theft deterrent module is programmed to store the first resistor pellet code it detects.

When the theft deterrent module is unable to detect a valid PASS-Key II resistor pellet code, the programming sequence never ends. During the programming sequence, the theft deterrent module performs the following actions:
^ Flashes the SECURITY indicator.
^ Enables the theft deterrent relay, which enables the starter circuit.
^ Sends a password to the PCM through the fuel enable signal circuit
The password enables fuel delivery to the engine.
^ The engine starts.
^ The programming sequence ends when the theft deterrent module is able to detect a valid PASS-key II resistor pellet code.

The engine starts. The programming sequence ends when the theft deterrent module is able to detect a valid PASS-key II resistor pellet code.
