Addendum to checking TCU error codes

[EdWindows]

The following should be added to the check TCU error code how-to:
The last step in the error-checking (pressing the pedal) may not register if you have a bad TPS that throws a CEL, and therefore you will not be able to retrieve TCU codes!

I noticed this because when I first bought my car, I had the 16 power flashes and tried and tried and tried checking TCU codes both ways with no avail. Everyone I asked here was convinced I was doing something wrong, or they didn't know why it didn't work.
After replacing my TPS, I was able to check my codes with both methods on the first try.

PS: A bad TPS also causes the power mode light to be intermittent when a Power Mode switch/button is activated.
