Only the dealership can access the codes...if the head unit is the same one that came with the car from the factory, just call up a dealership and talk to a service advisor. They can run a DCS on your VIN code a give it to you along with any open recalls or service campaigns that your car may need.

there are several TSB's pertaining to the anti-theft system. the best option is to see what part of the anti-theft system is not working. There should be codes in the theft module. you will need a high end scan tool to get these. anything less than $1,500 will not get these codes. You will likely have to get a GM dealer or a good independent shop to help you with this. Once the problem is resolved the anti theft can be relearned if necessary and you should be fine until the next thing goes wrong...
Hi Carol , do you mean PATS passive antitheft system ? Locked up your car ,do you mean it won't crank over an start ?
The passive anti-theft system uses radio frequency identification technology to deter a driveaway theft. Passive means that it does not require any activity from the user.
During each vehicle start sequence, the ignition key identification code is requested by the vehicle protection anti-theft electronics.
If the key's ID code has been programmed into the system, the powertrain control module (PCM) (12A650) is signaled to enable the vehicle to start.
If the key's ID code is not programmed into the system, or if no encoded key is detected, then the powertrain control module is signaled to disable the vehicle.
The passive anti-theft system communicates the state of the security system to the powertrain control module via the J-1850 communications network data link connector (DLC). The powertrain control modulebased on the communications from the passive anti-theft system, will determine if the vehicle's engine is enabled to start.
The passive anti-theft system differs from the active anti-theft alarm system in that the passive anti-theft system enables/disables the vehicle from starting and only operates with the ignition switch in RUN/START position. The active anti-theft alarm system has perimeter protection capabilities and operates only with the ignition switch OFF. Refer to Section 13-11A for active anti-theft alarm system information.
The passive anti-theft system will be activated and disable the vehicle from starting if any of the following conditions exist:
damaged encoded key
non-encoded key (key has no electronics)
Passive Anti-Theft System (PATS) control module concern
Absolutely! If the Passive Anti-Theft System (PATS) "thinks" you are trying to steal the car, it is SUPPOSED to keep it from starting. The problem is that the PATS thinks you are a car theif when you are not.
Below is a table straight out of the service manual for your vehicle. Please note that the FIRST action that must be taken for any PATS system malfunction is to scan the computer system for fault codes.
Unfortunately 90% of the time when you get error codes from the CD player/changer it means that there is a mechanical failure in the CD player/changer unit itself and it usually requires CD player/changer rebuild or replacement...
First make sure you have entered the correct anti-theft code. If battery power has been disconnected recently than the stereo display will read CODE if the incorrect anti-theft code is entered the display will read ERR1 thru ERR3. If this is the case you'll have to get the correct anti-theft code. Note; If you enter the incorrect code three times the stereo locks up. Disconnect the battery for more than 30 seconds and then retry.
FYI;Never use adhesive labels or protective disc covers on recordable CD's. Recordable CD's are actually thicker than pre-recorded CD's. Automotive players and changers use rollers to draw the disc into the unit. The added thickness of an adhesive label or protective disc cover may cause the disc to jam. Also CD players and changers are exposed to high temperatures inside the vehicle. High temp will cause the labels adhesive to soften which may cause the labels edges to curl or cause it to bubble. Either one may cause the disc to jam and cause the player to display error codes E-01 thru E-07. If the player can not be disassembled and have the discs removed successfully than it will have to be replaced. -hope this helps.
I own a 2002 Honda CRV. I bought it used and all owners manual was
provided with the purchase. I lost power to the car's system and the
radio set itself in an anti-theft mode requiring a code to get the radio
to function again. I tried pushing several buttons without succees. I need your help to put the right code!!
