Service bulletin SA-048-18

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some vehicles may crank but not start due to a PCM/Immobilizer malfunction. If this happens, check the status of Recall 3505H. If Recall 3505H has NOT yet been completed, perform the following steps: a. Perform and close recall 3505H. b. Order a new immobilizer (PN: BJ3D675G2L). c. Confirm at least two valid keys are present. Keys may be valid or new keys. Cut new transponder equipped key(s) if necessary. d. When new immobilizer is available, continue to REPAIR PROCEDURE. If Recall 3505H has already been completed, perform the following steps: a. Contact the Parts Test Lab (PTL@mazdausa.com) for a shipping label for the PCM. b. Send the PCM to the MNAO Parts Test Lab address shown below for erase/reprogramming. Attach a copy of the Repair Order when shipping the PCM. (See PCM REMOVAL/INSTALLATION). c. Order a new immobilizer (PN: BJ3D675G2L). d. Confirm at least two valid keys are present. Keys may be valid or new keys. Cut new transponder equipped key(s) if necessary. e. When reprogrammed PCM is returned and new immobilizer is available, continue to REPAIR PROCEDURE. NOTE: If the PCM cannot be reprogrammed due to a damaged PCM, the PCM will be returned to the dealer with notification of PCM damage. Check the eMDCS for PCM availability. If no parts are available, it is suggested to out-source the PCM.
