550 suspension light

Steve,

Check to see if the shock actuators were properly reconnected.

ECU reset?

 

Use the battery cut-off switch to disconnect the battery. Then reconnect with the switch and let the car idle for 5-10 minutes to reset the ECU.

It should shut off with a few restarts of your engine.

See this thread: Resetting suspension light

 

Steve, John and Barry, that procedure, the battery switch, is incorrect. all you need to do is a drive cycle if there are no other problems. As soon as the ECU receives a speed signal it will turn the warning light off.

If it doesn't then there is a problem somewhere. There are several things one can check themselves but it's shooting in the dark. Best is an SD 2/3 to pinpoint the problem. The Leonardo says it will but in fact it won't.

Some info here, disregard the comment about Corvette actuators as since then I debunked that theory.

Thank-you, Dave. I wasn't sure if the ECU reset was necessary as it's been a while since I last got a suspension light in my 550. Here is the thread I was looking for: Suspension Waring Light

After I pulled off the concrete strip next to the gas pumps, I shut off the engine. When I restarted, the light was gone.

I hate all idiot lights! I wish I still had my 1969 MGB. Now there was a dependable car...except when the Lucas electrical stuff acted up which was every other month and after driving through water puddles.

 

I wish I still had my 1959 Austin Healey 100-6 MM. Bought brand new in 1959 with the first hard top imported to California.

 

If you turn the ignition switch on/off more than five times without driving the car, the suspension ECU warning light comes on. It is looking for a vehicle speed signal. It sees that the ignition has been turned on multiple times does not see a vehicle speed signal, so it thinks that there is something wrong with the speed sensor.
You don't have to do a hard reset (disconnect the battery) to erase the fault, just drive the car and then shut it off. The next restart the light will be out.
