On my Honda Civic DX 2000, the Check Engine Light (CEL) has been on for a while, so I brought the car to AutoZone to have the OBD code read, but I was told that no code is stored in the computer.

Therefore I tried to get the OBD code myself by shorting the Service Check Connector (SCC) terminals. The SCC looks like the small connector in the following picture:

scc http://cdn.instructables.com/FSX/9QXV/F6S8S0A5/FSX9QXVF6S8S0A5.LARGE.jpgscc

I actually read an OBD code before by using this method before, so I am shorting the correct SCC terminals.

However, the following things happen this time.

  1. When I turn the ignition switch to position I, the CEL goes on and then goes off.

  2. When I start the engine, the CEL is off first. However, when the engine is started and then the engine speed drops a little, 10 seconds, then the CEL light comes on and does not flash at all.

What might be wrong?

Thank you in advance.
