Hello,

I recently bought an obd2 scanner from a auto parts store, and it read some code out of my Infiniti Q40. There were 4 codes in total and each of them showed low tire pressure on each tire, but those codes were appeared under the BCM section but not the TPM section (No codes were read out of this section), also I do not have any warning lights on my dashboard right now, but the tire pressure warning light did come on a few weeks ago when I was driving on the highway but it went off a minute later and never came on again. Plus the scanner could not scan multiple modules on my car, just simply said connections weren't able to be established. Could that be something wrong with my car (BCM, TPM, etc.) or just the scanner? Plz, help me out... Thanks very much!
