BCS COMBINATION SWITCH READING SYSTEM BCS-9 < FUNCTION DIAGNOSIS > C D E F G H I J K L B A O P N - The voltage waveform of INPUT corresponding to the formed circuit changes according to the operation of the transistor on OUTPUT side if any (1 or more) switches are ON. - It reads this change of the voltage as the status signal of the combination switch. Operation Example In the following operation example, the combination of the status signals of the combination switch is replaced as follows: INPUT 1 - 5 to “1 - 5” and OUTPUT 1 - 5 to “A - E”. Example 1: When a switch (TURN RH switch) is turned ON • The circuit between INPUT 1 and OUTPUT 5 is formed when the TURN RH switch is turned ON. • BCM detects the combination switch status signal “1E” when the signal of OUTPUT 5 is input to INPUT 1. • BCM judges that the TURN RH switch is ON when the signal “1E” is detected. Example 2: When some switches (turn RH switch, front wiper LO switch) are turned ON JPMIA0068GB ALMIA0260GB 2010 Pathfinder |
