Central Control Module/Pass-Key(R) Programming

The CCM is programmable so that the vehicle can be matched to a particular set of ignition keys having resistor pellets already embedded into them during manufacturing.

The procedure for programming a key resitance value into a new CCM is as follows:

Important
^ Do not allow more than approximately 10 seconds to pass between any of the steps in the following procedure or the program sequence will halt. If this occurs, the procedure must be started from the beginning.

1. Insert the first ignition key into the ignition switch and turn the switch to "RUN" position.
2. Turn the key "OFF" and remove it from the ignition switch. The program mode has bow been entered.
3. The CCM will prompt the technician to insert the appropriate key into the ignition switch by flashing the "SECURITY" lamp. The lamp will flash a number of times corresponding to the key number that is being programmed. At the CCM prompt, insert key number 1 into ignition, but do not turn the switch. During this step, the CCM determines the resistance value of the key and stores it in memory.
4. If a valid key is sampled, the CCM will prompt the technician to insert key number 2 into the ignition switch by flashing the "SECURITY" lamp twice. If an invalid key is detected, the CCM will exit the program mode and a trouble code will be stored.
5. The process will be repeated for key number 3, with the "SECURITY" lamp flashing three times as a prompt.
6. After the third key is inserted into the ignition switch, and all keys are detected to be valid, the system will finish programming itself and automatically exit the programming mode, indicated by the "SECURITY" lamp going out.

Important
^ In the programming process, be sure to use all three keys provided to the customer. Using one key three times will not ensure that the CCM will accept one of the other keys, should the customer lose the original key.
