Deployment Loop Resistance Measurement Test

This test is run during power-on and continuous monitoring diagnostics. The inflatable restraint Sensing And Diagnostic Module (SDM) performs this test in order to inspect for proper deployment loop resistance. This test is run after the voltage out of range test as long as a short to B+ does not exist within the deployment loops.
