Thread: Resetting codes?

Am I right in saying that all codes can be reset by disconnecting the battery leads and touching them together? My air suspension is still inactive and no faults came up whilst it was in the dealers,they reset, it was ok for about a week then one very cold morning it came up with the message again..I think it's a dud battery but I can't get the vehicle into the dealers easily as I live out of town and my work hours normally miss opening and closing times of the dealer..

Touching the two terminals together before re connecting them will ground the ECU's re setting them but in your case it sounds like your EAS has gone in to hard lock and needs the fault code cleared , you say no error code is showing is this on the dash or using a code reader like an IID tool ?
