WARNING:Vehicles are equipped with air bag supplemental restraint system. Before attempting ANY repairs involving steering column, instrument panel or related components, see SERVICE PRECAUTIONS and DISABLING & ACTIVATING AIR BAG SYSTEM in appropriate AIR BAG RESTRAINT SYSTEM article.
NOTE:Body Control Module (BCM) may be referred to as Platform Zone Module (PZM).
Vehicles are equipped with both the Personalized Automotive Security System (PASS-Key II(R)) and Universal Theft Deterrent (UTD) anti-theft system. PASS-Key II(R) is designed to prevent vehicle theft by disabling engine unless an ignition key with a specific electrical resistance is used in ignition key lock cylinder. PASS-Key II(R) system operates using sensing contacts which are located in ignition key lock cylinder. These contact a key resistor pellet which is located on the ignition key. When lock is rotated, battery voltage is applied through appropriate fuse to Instrument Panel Cluster (IPC). Pellet resistance is then compared with programmed value in IPC. At the same time, a signal is sent to Powertrain Control Module (PCM) to enable fuel.
If PCM does not receive fuel enable signal, PCM will in turn inform IPC to display STARTING DISABLED/DUE TO THEFT SYSTEM/REMOVE IGNITION KEY message on Driver Information Center (DIC). When ignition is turned off, IPC will start a timer and display wait messages on DIC. If timer is not allowed to run out, IPC will not send fuel enable signal to PCM. When PCM does not receive signal, IPC will restart message process. If fuel enable signal fails while engine is running, PCM will inform IPC to turn on THEFT SYSTEM PROBLEM message on DIC and trouble Code 58 will set. Engine will not stall and will restart if turned off, but system should still be checked.
System components include ignition key, ignition key lock cylinder, starter enable relay and Instrument Panel Cluster (IPC).
The UTD option operates separately from PASS-Key II(R) system. UTD sounds horn and flashes headlights in the event of forced entry through doors or trunk. UTD system does not affect engine starting.
DISABLING & ACTIVATING
ANTI-THEFT SYSTEM ARMING & DISARMING (UTD SYSTEM)
Close all windows and place shift lever in Park. Turn ignition switch to LOCK position and remove key. Open any door. Lock doors using electric switch or LOCK button on remote keyless entry transmitter. Close doors. After about 30 seconds, SECURITY indicator should go out, indicating system is armed.
To disarm system while SECURITY indicator is illuminated and doors are still open, move electric door lock switch to UNLOCK position. To disarm system after it has been fully armed, unlock door using a key (from outside), turn ignition on (from inside) or use UNLOCK button on remote keyless entry transmitter. To deactivate alarm once it sounds, unlock a front door using a key or use UNLOCK button on remote keyless entry transmitter.
Lol-how dare you say that-you have a great day squidman-aka sailor-bye for now
There is no reset for the system. If you are getting a message, and a no crank, you have a theft system problem. Easiest way to isolate it, is to check that the ignition cylinder is not at fault. If you know how to use a voltmeter, and can accomplish some simple trim disassembly, you can figure it out. Remove the lower insulator panel from under the drivers side of the dash. There is a large connector, that is held together with a 7mm hex bolt, disconnect that connector(it will have the flat turn signal and wiper switch connectors integrated). There is an orange wire conduit with two small white wires, that go to the wiper switch connector, two terminals on the end of the connector. Connect the ohmmeter across these two wires, insert the key, and rotate to all positions. You should see the same resistance value across all positions. somewhere in the k(1000) ohms range. This is the resistance of the key pellet(or should be). My guess is, you are going to see open circuit at some time, or all the time. This would indicate your ignition cylinder(not switch) is faulty. Replacement requires steering column disassembly, at least below the lock plate and turn signal switch, and also requires some special tools. If you haven't, try a second key to see if you get same result. If you do, it needs a cylinder.
