# Service bulletin 23\-01\-069G\-1

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

Certain 2023MY G80 Electrified \(RG3 EV\), 2023\-24MY GV60 \(JW1 EV\), and 2023\-24MY GV70 Electrified \(JK1a EV\) vehicles may have a condition where low 12V auxiliary battery charging occurs due to an ICCU \(Integrated Charge Control Unit\) fault and may set the following DTC P1A9096 – “DC/DC Converter Input Voltage Sensor Fault”. When a fault occurs, the vehicle may enter a reduced power mode while various warning lights, an audible chime will sound, and large messaging in the vehicle’s instrument cluster will appear, instructing the driver to stop the vehicle. The vehicle will be inspected for a DTC P1A9096 and may require either an ICCU software update or ICCU replacement and fuse replacement.
