Update. I cleared codes 2,5,8 &17 from the emissions module (LED/switch). However I could never get the two flashes confirming that all was clear. When the switch was held for the necessary 3-4 seconds and released the LED remained blank. The CE light remained on when starting the engine.

With the LED tool I went ahead and checked pins.

Pin 8 read 1 (clear).

Pin 14 read 5. I cleared.

Pin 10 would not give any signal not even 1.

Pin 7 read 1 (clear)

Pin 6 read code 8 and I am unable to clear it.

Upon restarting engine the CE light is off. I have not driven enough to see if it will come back on.

Why can't I get the emissions module to give a clear signal and what is the diagnosis for pins 14 and 6?
