HiCustomer Thank you for asking your question on JustAnswer.
Click below for pinpoint test. When the module sees all faults corrected the light will go off right away. The codes will stay in RCM memory for x amount of key cycles but the light will go off right away if the key is cycled and no hard faults exist.
That is the entire test for B2292 which is for the buckle side pretensioner. The retractor pretensioners are called load limiting retractors and if at fault will trip a B1085. The codes are generic (they cover the entire circuit including wire problems module problems etc... If you want specifics on the code i.e short,open etc.. then you need to retrieve the bit mapped codes which also requires an IDS scanner. The bit mapped codes look like this B1085_01 B1085_02 etc...
Here is the PPT for B1085.
Sorry about that - clicked the wrong year : ( Here is the 07 for 1085
