Manufacturer summary

Original wording in English

Certain GV70 Electrified (JK1A EV) and G80 Electrified (RG3 EV) vehicles may display a false warning light with Diagnostic Trouble Codes (DTC) U151A8C and/or U151B8C when vehicle is placed into “Ready” mode. This bulletin provides the procedure for updating the Vehicle Control Unit (VCU) software to address this condition.

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.
