Manufacturer summary

Original wording in English

This technical bulletin provides a procedure to update the ECM to the latest software and calibration available to correct a customer concern that the Malfunction Indicator Lamp is illuminated and/or the remote start will not start the vehicle due to a voltage spike in the ECM, above the threshold value which will set the code P0132 or P223E.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
