Circuit Description
WARNING: This page is about a different car, the 2003 Suzuki Vitara. 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 stop lamp switch input to EBCM from changing states when the brake is applied. EBCM sends a low current 5 V sense voltage on brake switch input line to the rear brake light bulbs. If rear brake light circuit is intact, this voltage will be pulled low (under 1 V) 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 EBCM, indicating brake lights are on. If voltage is neither low (under 1 V) or high (battery voltage), EBCM cannot determine brake switch state and DTC C1295 will be set.
