Code 31, Open 36VLR To Deployment Loop: Description

Voltage at SENSE LOW input is 41-61 percent of 36-Volt Loop Reserve (36VLR) output when 36VLR output of Diagnostic Energy Reserve Module (DERM) is functional. Should circuit open between 36VLR output and arming sensor, IGNITION 1 voltage will supply deployment loop. Voltage at SENSE LOW input will decrease due to lower supply voltage and Code 31 will set after 700 milliseconds (if Code 42 is not set). Code 31 indicates an open in wiring between 36VLR output of DERM and arming sensor.
