"Service engine soon" light

Once the SES light starts blinking, it is actually blinking out the DTC fault codes that's causing the SES light to be illuminated. It's a 4 digit code...the long flashes are the first digit (ten flashes for 0) and then it will quickly flash the 2nd digit, pause, quickly flash the 3rd digit, pause, quickly flash 4th digit and pause, repeat. No codes is 0000. So, with this, there is no need to have the codes read by anyone...the car will tell you what the codes are.

You can depress the accelerator pedal to erase codes and reset ECM ANYTIME during the codes being flashed out. So, this is much more than just a way to reset the ECM and SES light.

This is a tricky thing to do and that 7 seconds is VERY difficult to time exactly right. Need a stopwach for sure with this because it is a VERY EXACT process with timing it. Usually takes me 3 or 4 tries to get it right. Turn ignition off for ~10 seconds between tries.

NOW...for the next trick.

At the END of the 7 seconds, you floor the gas pedal and it SHOULD start flashing codes after 10 seconds if you've done it correctly. If you keep the acc pedal to the floor after it starts flashing and just keep it there for about 10 seconds after it starts flashing, the SES light will stop flashing and light up solid. IF you start the car within 3 seconds, that is the idle-air volume relearn. Any kind of intake mods will require you to do this.

To do this, the engine must be at operating temp, ALL accessories OFF, steering wheel pointed straight ahead, vehicle in neutral and no fault codes stored. Just let the engine idle for 2 or 3 minutes then race the engine a few times and verify that it falls smoothly back to a normal idle speed. DONE.
