Construction

• Allows visual confirmation of immobilizer system operation.
• If any malfunction is detected in the immobilizer system, the malfunction location can be verified by the security light flashing pattern.

  Note
  • If there is security light system malfunction, DTCs may not be properly displayed. Always use the Mazda Modular Diagnostic System (M-MDS) to verify DTCs.

Operation

• When the immobilizer system is operating, the security lights flash repeatedly 0.1 s every 2 s.
