When A Module Is Left Unprogrammed After Repl. (except SEO)
When replacing a theft deterrent module. It must be programmed to accept the resistance value of the existing vehicle keys to allow PASS Key II operation.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(R) II resistor pellet code, the theft deterrent module will never end the programming sequence. During the programming sequence, the theft deterrent module performs the following activities):
^ Flashes the Security indicator.
^ Enables the theft deterrent relay, thus enabling the starter circuit.
^ Sends a password to the PCM through the fuel enable signal circuit to enable fuel delivery to the engine.
^ The engine starts.
^ The programming sequence ends when the theft deterrent module is able to detects a valid PASS-Key(R) II resistor pellet code.
