Information

Refer to the notes and text for repair information when servicing customer PATS concerns.

PATS Type by Model

^ 1999 - 2000 B3000/B4000 (with PATS) - PATS Type B

^ 2001 - 2004 B2300/B3000/B4000 - PATS Type E

^ 2001 - 2004 Tribute - PATS Type E

Glossary of Terms

^ PATS: Passive Anti-Theft System

^ Anti-Scan Mode: This PATS feature will not allow the vehicle to start for 30 seconds if an unprogrammed key is tried. After 30 seconds, the vehicle will start if the proper PATS key is programmed. Until the Anti-Scan feature resets, no keys will start the vehicle. When trying to start a vehicle with an unprogrammed PATS key, the theft light will flash rapidly and the vehicle will not be able to start. In this case, leave the key in the ON position for 30 seconds for the Anti-Scan feature to time out. If this time-out is not completed, the vehicle will continue to not start, even with a programmed key.

^ As Built Data: Base vehicle specific data stored in the PCM which allows the PCM to operate on a specific vehicle.

^ Tick: This is a WDS command, similar to "enter" on a computer. The tick is on the right-hand side of the screen, and is shown as a blue check mark.

Notes and Additional PATS Information

^ Erasing and reprogramming the customers ignition keys does not cure any known intermittent PATS "no start" issues. Do not simply reprogram the ignition keys if a fault cannot be identified.

^ Only Mazda Genuine key blanks should be used on PATS equipped vehicles. Aftermarket keys may cause PATS issues.

^ Diagnostic Trouble Code (DTC) P1260 in the Powertrain Control Module (PCM) is a direction to retrieve fault codes from PATS. Retrieve fault codes from the appropriate PATS function and follow those pinpoint procedures before any further PCM diagnosis.

^ Vehicles with PATS Type B send an enable message to the PCM if proper conditions are met. The PCM then allows fuel injector and fuel pump operation. The proper conditions are: 1) a valid key read and 2) proper PATS-PCM initialization.

^ Some vehicles with PATS Type B may include a starter interrupt. These vehicles do not necessarily have to exhibit a no crank situation to constitute a PATS related no start.

^ Check for a remote vehicle starter and remove any such equipment from the vehicle before continuing diagnosis.

^ Some aftermarket audio equipment has been found to keep the ON/START circuit active for over 5 seconds past ignition OFF. This can prevent PATS from properly reading ignition keys during key programming. Remove or disable this aftermarket equipment if problems with any key programming sequence occur.

^ When using the NGS select only the functions mentioned with the procedure. Selecting incorrect functions (or additional uncalled for functions) may result in a no start condition and the need for further diagnosis and repair.

^ Reprogramming of the PCM does not have any impact on PATS, if the procedure functions as intended.

^ If the vehicle does not start and there is normal prove-out of the theft indicator and DTC P1260 is not stored in the PCM, then the vehicle has a non-PATS related issue preventing the vehicle from starting.

^ If the vehicle (PATS Type B only) is a no start with the theft light flashing at ignition on, and with no DTC P1260 stored in the PCM, check PCM power, ground, and VREF circuits for opens or shorts, then the PCM may not be operating properly.

^ If the engine does not crank on vehicles that have PATS operating the starter relay, verify PATS output to the starter relay. Also verify the PATS power and ground circuits.

^ After performing a key erase procedure on a PATS Type F system, disconnect the diagnostic tool and leave ignition in ON for 10 seconds, then turn ignition OFF and add keys.

^ PATS Control function is located in: the PATS Module for PATS Type B, and the PCM for PATS Type F.

^ Theft indicator prove-out (when ignition to ON) period is 3 seconds for both PATS Type B and F.

^ Theft indicator (at key OFF or ACC) flashes every 2 seconds for both PATS Type B and F.

^ Maximum number of keys that can be programmed is eight (8) for both PATS Type B and F.
