Mazda 2: Foreword [Immobilizer System (Keyless Entry System) ]
- DTCs are recorded in the PCM and instrument cluster when a malfunction
is detected.
The stored DTCs can be verified using the flashing pattern of the security
light and M-MDS.
There are some DTCs which cannot be verified using the security light.
Verify the DTCs that were detected using the M-MDS prior to beginning the
servicing. (See DTC INSPECTION [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM) ]
).
- If more than one DTC is detected, the security light only displays the
DTC with the
lowest number. Begin repairs based on the DTC displayed by the security
light. All
DTCs can be read by the M-MDS.
- It is possible for several DTCs to be displayed for one malfunction
cause. Erase the
DTCs after one repair and then re-inspect the DTCs.
- If immobilizer system DTCs are not recorded even if the engine cannot be
started, perform symptom troubleshooting. (See NO.3 WILL NOT CRANK] ).
- The PID/data monitor function can be used to verify the number of key ID
numbers programmed for a single vehicle. (See PID/DATA MONITOR INSPECTION
[IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM) ] ).
NOTE:
- Due to the possibility that the engine cannot be started because
transmission between
the key and the vehicle is obstructed, do not allow the following items to
contact the
key ring.
- Any metallic object
- Spare keys or keys for other vehicles equipped with an immobilizer
system
- Any electronic device, or any credit or other card with magnetic
strips
