Does anyone know the proper way of resetting the maintenence light on a 1997 Acura CL? I think you stick a key in the slot in the dashboard, but I'm not sure what else you need to do. Does it have to the the car's ignition key for it to work? Do you need to turn it? Do you have to press in and turn the engine on? Please help. The light is driving me crazy.

 

the keyhole is for the maintenance square on the speedo. the check engine light you have to erase with a code scanner through the obd-II connector

 

Go to the Autozone, borrow a scanner tool, remove the ash tray under the radio, plug the scanner tool in, turn the ignition ON, press READ on the tool, write down what the code is, then use the CLEAR CODE option on the tool to clear your CEL...

 

 

Or fix the problem and reset the ECU
