I2C no response

[bsxiong]

I just got the unit today and I can't seem to get it to work.
Car: Honda Civic 96 LX 4dr Manual

I plugged in the unit and it turned blue a couple of times. Then it turn red. Then it turns off. (I assume it's okay)

I loaded up the sketch, "rpm_led_i2c".
1. Nothing happens.
2. I added Serial.begin(34800) and do a println(). It doesn't even get to the loop().
3. I just get "AT" repeatedly.

I loaded up the sketch, "obd_i2c_test".
1. Nothing happens.
2. Nothing is printed.


Note: I have UNO R3. Green -> A1, White -> A0. I've also tried swapping these two as well.
I've tried TX and RX on the UNO board and same thing.

Please advise

Thank you,
