Symptom:
PASSENGER AIRBAG ON - OFF SWITCH OPEN
When Monitored and Set Condition:
PASSENGER AIRBAG ON - OFF SWITCH OPEN
When Monitored: When the ignition is on, the PAB MUX Switch Sense circuit supplies a
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 an open or high resistance on the PAB
MUX Switch Sense circuit or PAB MUX Switch Return 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
referred to as an ACM.
SELECT ACTIVE or STORED DTC:
ACM - ACTIVE DTC
ACM - STORED DTC
NOTE: When reconnecting Airbag system components, the ignition must be
turned off and the battery must be disconnected.
2 WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNI-
TION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BE-
FORE PROCEEDING.
Disconnect the Passenger Airbag On-Off Switch.
NOTE: Check connectors - Clean and repair as necessary.
Measure the PAB On-Off Switch resistance between terminals 1 and 2 in both switch
positions.
The switch resistance specifications are: ON position = 175.0 to 190.0 ohms and OFF
position = 820.0 to 870.0 ohms.
Is the resistance within range for both switch positions?
Yes → Go To 3
→ Replace the Passenger Airbag ON-OFF Switch.
No
