Hello All,

Just bought a used 09 mdx and after the first rain in the central valley, California, the check sh-awd system light came on after I started the engine after driven a few miles in the rain. On the info message panel it shows code 44 and according this code it got to do with the sh-awd control unit but there are a few numbers related to this problem...I am going to have it diagnosed but before I do that I'd like to know if its OK to disconnect the battery? Could disconnect the cause other problem? Appreciate any help on this...thank you.

Also beside the warning light, the sh-awd display only shows the front wheel drive running lights, no movement for the rear. Would disconnect the battery reset this warning light ?

Check your relay located in the trunk. I had a similar issue and swapping the two relays solved the issue so good idea to start there.
