Theft Deterrent Feature

The AM/FM tape and the AM/FM/tape/CD radios are equipped with a programmable theft deterrent feature intended to discourage theft by causing the player to be inoperable if the theft deterrent feature is armed (in the SEC state) and the power is interrupted for more than 20 seconds between the battery and the radio. Power can be interrupted if the radio is removed from the vehicle, if the battery is disconnected, or if the 10A RADIO (BAT) fuse is removed or opened.

When the vehicle is first purchased, the radio theft deterrent feature is unarmed.The customer must program a 4-digit code to secure (arm) the radio.

The theft deterrent feature causes three main radio operating states: vulnerable (unarmed) mode, secure (armed) mode, and locked mode.
^ VULNERABLE (UNARMED) MODE- the radio does not have a four-digit code stored. If stolen, the radio will not lock and will retain normal operation when battery power is resupplied.
^ SECURE (ARMED) MODE - The radio has a four digit code stored. To deactivate the feature, the four digit code must be reentered. If battery power is removed for more than 20 seconds while in the armed mode, the radio will enter the Locked Mode.
^ LOCKED MODE - The radio has been removed from battery power for more than 20 seconds or the wrong deactivation code has been entered three times while in the Armed Mode. The radio will only return to normal operation if the code is re-entered as outlined below.

Before performing service on a vehicle, verify that the theft deterrent feature is unarmed. This can be done by turning the ignition On and turning the radio Off. Then press and hold presets 1 and 2 for 5 seconds. If the theft deterrent feature is armed, a four-digit number will appear on the radio display. Ask the customer to deactivate the feature. If no number appears, the theft deterrent feature is unarmed and service may be performed on the vehicle.
