Multiple warning lights and air suspension failure

[agislht]

I am getting multiple warning lights that come on intermittently that they cause my air suspension and AC to stop operating until they go off. I get the battery indicator, oil light, and radiator lights on. They flicker and sometimes I hear what sounds like a sizzle noise. I have checked the connectors and they are all tight. I have replaced the relays under the hood and still the problems persist. If I turn off the AC it will sometimes cause the lights to go off, but not for long. HELP!!! Anybody have any ideas?

Can't tell you exactly what's going on, but my hunch is the ECU might be relaying bad information. Since I don't know, try to consult a Toyota Dealer or at least an Aftermarket Electrician. They should be able to get you some indication to what's going on.
