Clock will reset overnight

[ebox86]

I have experienced this for a couple of days now. Every other night, not every night but every so often, after i start the car up for the first time in the morning, the clock and radio will be reset. The battery doesn't seem to be draining and there is no trouble in starting, no strain like the battery is draining off of something.

Some mornings it will retain its values, other mornings it will not and everything is reset.

Any ideas on what that might be? Its annoying having to reset the clock every other morning

thanks

loose power cable to the OBC?

Is the power cable to the obc the one under the dash near the firewall? I think the connector is a green color? Kind of looks like a rectangle?

I will check this area and also see if the battery terminal connections are secure as well

anywhere else?

Si board powers and performs calculations for the OBC. I would start by replacing the fuses for the OBC circuits and if problem continues, replace SI board batteries if they have never been changed.

what about the radio resetting? When this happens, the clock not only resets but also the radio, loosing all my presets and requiring the code to turn back on

Replace your old fuses, especially 10, 12, and 21 and any other associated with OBC and radio.
