H2 BCM question
Hi Everyone,
A while back I had a few DTC codes related to communication with BDM. for a few seconds I noticed cabin lights were not normal. My mechanic cleared the codes and told me I might need to get a new BCM. Since then i've been driving around, and meanwhile I ordered a bluedriver obd2 scanner and keep monitoring the logs, but no more of those codes and the H2 seems to be fine.
IS that possible that could be a glitch in the system. should I keep monitoring the logs ? or is it better to reprogram the BDM and check the connection anyways. Many thanks

Could very well have just been a glitch however the BCM is one component that is susceptible to getting wet if there is a leak allowing water to get in. The BCM is way behind the headlight switch with the back of it pretty much against the firewall where any leaking water from the roof will run down...
