Code 35, Discriminating Sensor Open: Description
WARNING: This page is about a different car, the 1992 Oldsmobile Custom Cruiser, 1992 Chevrolet Caprice, and 1992 Buick Roadmaster. However, it is still accessible from the selected car via links, so may be relevant.
Code 35 is set when voltage at SENSE LOW input (terminal A6) is within a specific range of 36-Volt Loop Reserve (36VLR) output voltage for 500 milliseconds during CONTINUOUS MONITORING tests performed by Diagnostic Energy Reserve Module (DERM). CONTINUOUS MONITORING tests are performed by DERM after initial TURN-ON tests are completed and every 100 milliseconds while IGNITION 1 voltage is present at DERM. If a discriminating sensor is open, voltage at SENSE LOW input will increase due to increase in resistance of discriminating sensor section of deployment loop, and Code 35 will set.
