My airbag light stays on constantly. When first starting it blinks 5 times pauses then 2 times. So what does code 52 mean? Any info would be appreciated.

 

I waited to see if anyone would give you the answer.
52 is the back up power supply source to the system.
What this is is a large value capacitor that will discharge it's voltage during a crash event that actuated the bag system to be sure, in cases where the battery may become disconnected, broken or whatever might happen, and interuppt it's ability to supply the system voltage.
You must be very carefull working on a live system lest you blow the bag. Never use a resistant measuring meter in a live circuit or on the bag it'self. Reason is the meter has a battery inside.
