"I flicked the key three times and did not get any result."It's not clear to me that you performed this correctly. To read codes with the key, you turn the ignition to ON, then OFF, then ON, then OFF and then ON - and *leave* it on the third time. You should see a Check Engine light and also some message on the digital odometer. If the Check Engine light flashes, you count the pulses, keeping in mind that they are two-digit codes, so there will be a number of flashes, short pause, more flashes, then a slightly longer pause before the next two-digit sequence.Please try this again before buying a PCM.

Turned the key to both on positions for the sequence specified. The first position did not show the box around the transmission position, the second did. still no codes following the instructions.  BTW: The check engine light comes on as a check, but goes right out when the key is left on.

It's confusing to me what you did, but I think you did the sequence wrong. You should turn the key to ON, back to OFF, then ON, then OFF and then leave it ON, *all within 5 seconds*. If you delay this ON-OFF sequence too much in any position, you do not get the codes flashing. The fact that the bulb lights does indicate that it's working and probably communicating. Please try it again.

Probably not. Did you perform the code test again?
