2021 Mazda CX-3 AWDFACTORY OEM SERVICE PROCEDURE

Forced Ignition On

NOTE:
  • In order to perform a forced ignition ON, the M-MDS is necessary. If the servicing is being done outside of an Authorized Mazda dealership, contact an Authorized Mazda dealership for instructions.
  • The forced ignition ON procedure forces a power supply to each part when no power is available even after the ignition switch has been operated. However, the engine cannot be started and the steering cannot be unlocked.
  • When performing a forced ignition ON procedure, remove all remote transmitters from the vehicle. If a remote transmitter is left in the vehicle, the forced ignition ON procedure cannot be done.
  1. Verify that there are no remote transmitters in the vehicle.
  2. Obtain the Mazda PCM part number from MGSS, "As Built Data."
