Engine Control System: Removal & Installation Mazda Tribute I facelift

KEY PROGRAMMING AFTER PCM REPLACEMENT

Note. This procedure is used to reprogram the PATS keys (two keys needed) after programming the PCM.

1. Connect NGS Tester and turn key ON, Engine Off (KOEO).
2. Select model year. If the model year is not displayed, use 2001.
3. Select correct Tribute model in Vehicle Selection (YF is for 14 and AJ is for V6).
4. Select Diagnostic Data Link and press Trigger.
5. Select PCM and press Trigger.
6. Select Function Test and press Trigger.
7. Screen displays "Enter Security Access". It will take approximately 10 minutes at this point to gain access. Look at a clock or watch (since the screen does not count) and press Trigger.
8. In 10 minutes, the screen will change. Select ignition Key Code Erase and press Trigger. Screen will display "Process has been completed" When finished.
9. Turn Key OFF and disconnect NGS Tester.
10. Initialize the first key by inserting into ignition and turning Key ON, Engine OFF (KOEO) for at least 30 seconds and then turning Key OFF. Turn Key ON, Engine OFF (KOEO) and verify that the PATS indicator in the instrument cluster illuminates and remains illuminated. Turn Key OFF and remove.
11. Initialize the next key by inserting into ignition and turning Key ON, Engine OFF (KOEO) for at least 3 seconds (with security light illuminating for 3 seconds and then going out) before turning Key OFF and removing.
12. Confirm reprogram of keys by starting the engine with each key.
