   -5. Measure the resistance between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Selectable energy absorption device 2P connector (on the floor wire harness): disconnected
   	SRS unit connector A (39P): disconnected
   	SRS unit connector A (39P) No. 2 and No. 3: connected to SRS short canceller
   Test point 1	SRS unit connector A (39P) No. 2
   Test point 2	SRS unit connector A (39P) No. 3

   Is there an open circuit, or at least 1 MΩ?

   YES
