11 Characteristic of input signal * Input signal senses using 2 kind of voltage. - 5 volts - 12 volts In case of recognize signal using 5 volts. 1. Awareness voltage of switch are output from BCM If switch turned ON, output voltage drop to 0 volts. And, tail lamp relay turn "ON" 2. At this time, when switch turned ON BCM recognizes switch signal though voltage Are below than 1volt (Low signal) 3. If switch turned off, the voltage going up to high lever. This time, voltage level that recognize switch off signal is higher than 4volts. 4.Thus, the switch signal is not recognize voltage between 1.1 volts and 3.9 volts. In case of recognize signal using 12 volts. Extent that recognize switch's on/off signal is - ON : lower than 4 volts - OFF : higher than 7 volts 5 volts Battery Tail lamp switch 5 volts Battery Tail Lamp Relay Tail Lamp Door switch Key in switch B C M CPUCPU
