P1792
SPORT MODE INDICATOR - P1792The sport mode lamp is located in the instrument pack. The input is "pulled up" to nominal battery voltage (+12V) and is supplied by an ignition switch feed. The TCM drives the signal to ground to turn the lamp ON. The diagnostic runs on the sport mode indicator output continuously during initialization and operation. The check can detect an open circuit, a short circuit to battery and short circuit to ground, although the diagnostic cannot distinguish between an open circuit and a short to ground.
