Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that performed work without a confirmed outcome: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

2 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

From what I�ve heard, putting a 6Ohm 50W load resistor in parallel with each LED brake light you install also fixed this issue.

POST 1 / ORIGINAL POSTEROriginal post

Just want to share what happened to me last night, in case someone else run into the same scenario and haunted by PSM/ABS Warnings. Since LED tail lights for widebody 996s (C4S, Turbo, GT2) are not available* ( only one that fits are these one and the brake's red doesn't line up with the iconic red stripe engine compartment lid) So I went with a set of LED bulbs with circuitboard to avoid hyper flash or dashboard warnings. Everything went well, no hyper/rapid turn signal blinking all around, no dashboard warnings. But, as soon as I took her out, ABS and PSM Failures came on. Thanks to this post on 6speed , someone mentioned about the voltage/signal bouncing between the brake lamps and the ABS/PSM modules, which the replacement LEDs' circuit failed to mimic perfectly. So I replaced the brake lamp LEDs back to OEM and the warnings went away immediately...

From what I�ve heard, putting a 6Ohm 50W load resistor in parallel with each LED brake light you install also fixed this issue. You don�t get the power savings benefit of LEDs, but you get the faster on switching and longer life.
