About this document
Nissan ASCD Brake Switch Diagnostics by David Quispe is a document available to read on EtoBox.
The ASCD brake switch and stop lamp switch detect the state of the brake pedal. When the brake pedal is depressed, the ASCD brake switch turns off and the stop lamp switch turns on. The ECM detects the brake pedal state based on the on/off signals from these two switches. To check the overall function of the switches, observe their output with the brake pedal released and depressed. If not functioning properly, check the wiring harness and connectors, fuses, and inspect the individual switches.
