I experienced the same problem . On my 2005 Endeavor , I disconnected the
3 harnesses under the seat to have good access under the driver's seat.
After re-plugging the 3 harnesses , the SRS lights would come on . I disconnected the battery for 5 minutes , but the SRS light still stays on . Today I went to my dealer .
They charged me $ 25 to remove the code . The system is under warranty but not
the diagnosis . They removed the code with the Mitsubishi scanner ....
I should have known this trick : before un-plugging any system related to SRS :
DISCONNECT the battery , even the Negative , touch/short together the
2 harness +/- to avoid any sudden static charge that could trigger a bag ...
Make sure the negative harness do not touch the frame during the whole process.
At reconnection of the battery = the system will be back as normal without
registering a fault in the memory ......
Hope this will help.... :grin:
