dealers.

Campaign Description
Certain 2022-2023MY IONIQ 5 (NE1) and 2023MY IONIQ 6 (CE1) vehicles may exhibit a condition where low 12V
auxiliary battery charging occurs due to an ICCU (Intelligent Charging Control Unit) fault which 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
potential fuse replacement (if fuse is blown when inspected).

Hyundai EV Web Series (SVCHEV26EXAMW22_1176)
IMPORTANT: Follow the inspection process as outlined in TSB 23-01-060H (or latest version).
•

Service process requires inspection first and ICCU replacement only if DTC P1A9096 appears.
o If vehicle passes the inspection, will only need a software update.
o If vehicle does not pass the inspection and has DTC P1A9096, vehicle needs ICCU replacement.
 Do not put the vehicle back together with an affected ICCU and send the customer on their
way in the interim or just replace the ICCU fuse.
 Once ICCU is replaced, need to inspect fuse to confirm if blown or not. If blown, replace fuse.
 Never install a fuse before the ICCU is replaced as it will cause damage to the battery PRA
and cause Diagnostic Trouble Code (DTC P1B77).
