Condition 4

WHEN A THEFT DETERRENT MODULE IS LEFT UNPROGRAMMED AFTER REPLACEMENT
(Not Applicable To SEO Equipped Vehicles)

When replacing a theft deterrent module, it must be programmed to accept the resistance value of the existing vehicle keys to allow PASS-Key(R) 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 actions:
^ Flashes the SECURITY indicator by grounding intermittently circuit 728.
^ Enables the theft deterrent relay by grounding circuit 625.
^ Sends a password to the PCM through circuit 229 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.
