When Monitored and Set Condition:

When Monitored: With the ignition on, the MUX Switch Sense circuit supplies a 3 to 10 ms pulse every 100 ms across the switch resister to the MUX Switch Return circuit. Once the code is active, the ACM will disable the indicator for the duration of the ignition cycle.

Set Condition: The code will set if the ACM senses constant voltage over approximately 4.0 volts on the PAB MUX Switch circuits.
