Rear differential sensor diagnostics connector for the RABS system.
Undocumented in the service manual, but a technician can make a quick resistance check across those two pins and measure the parallel resistance of the rear ABS sensor and the input circuitry of the RABS module. A reading of 1.5K or less indicates the sensor and the wiring harness is intact.
A tech could also use a scope or AC meter to monitor the output signal of the sensor for further diagnostic testing.
