Symptom:
PASSENGER AIRBAG ON - OFF SWITCH SHORT TO GROUND
When Monitored and Set Condition:
PASSENGER AIRBAG ON - OFF SWITCH SHORT TO GROUND

3 to 10 ms pulse every 100 ms across the On or Off switch resistor to the MUX switch
return circuit.
Set Condition: The code will set if the ACM senses low resistance on the PAB MUX
Switch sense circuit.

TEST
1 NOTE: Ensure that the battery is fully charged.
Turn the ignition on.
NOTE: For the purpose of this test, the AECM and ORC modules will be
