Manufacturer summary

Original wording in English

This is a TJ - text only no attachments - If a customer experiences a DIM message stating "Propulsion System Service Required" and DTC IGM P06B400 is set, please follow the advice under "Service". Verify that the vehicle has software version 5.1.21 or newer. If necessary, update the vehicle's software according to TJ 31543. If the vehicle already has software version 5.1.21 or newer, or if the DTC comes back after the software update, replace the IGM.

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.
