Rear Combination Light Assembly: Inspection

WARNING: This page is about a different car, the 2021 Subaru Ascent. However, it is still accessible from the selected car via links, so may be relevant.

Apply battery voltage between the connector terminals to check the lighting condition of the light.

CAUTION: When applying battery voltage, do not mix up the positive (+) side and the negative (-) side.
Incorrect polarity connection may cause internal LED damage.
