Codes as follows:
P0073 ambient air temp
U0121 (multiple offenses)
U0002 (maybe also multiple)
U1120

After multiple attempts everything but the U1120 was able to be deleted. My reader only says that:
U=Network
0 in the first slot=generic
1 in the first slot= manufacturer specific
1 in the second slot= fuel and air metering
3rd and 4th slots identify malfunctioning circuit.

It's really only useful for P0xxx codes.

There does not appear to be an issue related to the alarm. There are no blinking lights/clicking when I get in, everything else works and the key/fob will lock/unlock the doors no problem.

It's not perfect.
It's not correct.
It's not yours!
