PURPOSE
In cold temperatures, the PTC heater relay for the main battery may temporarily freeze. This may
cause a MIL to come on or an EV warning message to display when turning the vehicle to the Ready
mode. An anti-freezing relay and a relay cover with a new shape is available to prevent this from
occurring.
AFFECTED VEHICLES
2018 - 2020 Outlander PHEV vehicles built before February 1, 2020.
REPAIR PROCEDURE
When a MIL comes on or an EV warning message is displayed in the Ready mode, and all the DTCs
listed below are stored, replace the PTC heater relay with the anti-freezing relay (p/n 8627A049)
and replace the current relay box cover with the new one (p/n 8565A645).
If other DTCs are stored, or all the DTCs listed below are not stored, there may be another root cause.
In this case, do NOT replace the relay and cover - diagnose per the Service Manual.
