Circuit Description
WARNING: This page is about a different car, the 2004 Suzuki Verona. However, it is still accessible from the selected car via links, so may be relevant.
This DTC is used to identify open stop lamp switch circuitry that prevents the stop lamp switch input to the EBCM from changing states when the brake is applied. The EBCM sends a low current 5 volt sense voltage on brake switch input line to the rear brake light bulbs. If the rear brake light circuit is intact, this voltage will be pulled low (under 1 volt) to ground through the rear brake light bulbs. When the brake light switch is depressed, battery voltage will be supplied to the rear brake lights and to the EBCM, indicating brake lights are on. If the voltage is either low (under 1 volt) or high (battery voltage), the EBCM cannot determine brake switch state and DTC C0095 will set.
