B0831 has no published definition; J2012 extracts, factory literature and NHTSA records are silent on it. Its title names the right front indicator circuit. In the GM-era Saab 9-3 this lamp is checked as B0525 by the front electrical centre, with the same limits as on the left: under 50 mA means open (04), while over 6 A lasting beyond 6 ms is read as a short to ground (02) and cuts the output. The same number B0525 is reused by the rear centre for the right rear lamp, so the module reporting the code matters. FMVSS 108 makes every car carry a flasher, a pilot indicator and a hazard warning system. HELLA lists defective bulbs, corroded contacts and damaged plugs as the common culprits. Left front: B0830; right rear: B0841.

Likely causes

Right front indicator bulb failed
Water in the lamp housing corroding the contacts
Wire damaged after front-end repair or impact
Front electrical centre output faulty
