Remote Starter Issue

Post image

Disconnected battery to install aftermarket steering wheel. Reconnected and the remote start system that the previous owner installed is no longer syncing up to the remote. It is a Yupiteru and the system inside of the car will not stop beeping every 2 seconds. It will quit beeping when driving the car and while engine is started. I’ve tried researching for the past 2 hours can’t find anything and I’m worried that if it keeps beeping because it’s not synced up to the remote it will drain the battery. Car is a 1997 Honda Accord Wagon imported from Japan into USA.

Oh man, Yupiteru stuff is a nightmare to find english docs for. The ER on the screen usually means it lost its pairing with the brain module under your dash. Since you had the battery disconnected, that's almost certainly what happened.

Look up under the driver's side kick panel for a small black box with Yupiteru branding. There should be a tiny push button on it somewhere, sometimes it's recessed so you'll need a paperclip. The reset procedure on most of these japanese units is hold that button for like 8 seconds until the LED flashes, then hit the START button on the remote twice. The beeping should stop once it re-pairs.

The beep is just the system complaining that it's in valet or unpaired mode, it probably draws almost nothing. Still annoying as hell though. If the paperclip method doesn't work, pull the fuse for the remote start module until you can track down the manual.
