2019 Model S Raven – Adaptive ride control unavailable
(TAS_a168 front-right rebound). Fixed by reseating the connector, no lift or jack.
Got the usual pair of alerts: adaptive ride control unavailable / vehicle speed limited. Service Mode showed TAS_a314_dampingReduced and the useful one, TAS_a168_damperValveRbndFR – front-right rebound damper valve unplugged, shorted, or faulted. It was intermittent. Cleared after the car sat for an hour, then occasionally came back.
No need to jack it or pull the wheel. Set suspension to Very High and turned the wheel to full right lock. The damper valve body sits outside the wheel-arch liner, so nothing has to come off. Two plugs on it: the longer wire loop is rebound, the shorter is compression.
Powered the car off (Controls → Safety → Power Off), unplugged the rebound connector, sprayed DeoxIT D5 in the plug and socket, let it flash off, and clicked it home. Short test drive afterward had no alerts.
Too early to call it permanent – the fault was intermittent – but the code pointed at that exact plug and it’s quiet so far. Photos of the valve body and the rebound connector.
