APPLICABILITY

NOTE: Ensure that the battery is fully charged.
WARNING: TURN IGNITION OFF, DISCONNECT THE BATTERY AND WAIT
TWO MINUTES BEFORE PROCEEDING.
WARNING: IF THE AIRBAG CONTROL MODULE IS DROPPED AT ANY
TIME, IT MUST BE REPLACED.
Disconnect the Passenger On-Off Switch connector.
Disconnect the Airbag Control Module connector
NOTE: Check connectors - Clean and repair as necessary.
Measure the resistance of the PAB MUX Switch Sense between the ACM and the
PAB On-Off Switch connector.
Measure the resistance of the PAB MUX Switch Return circuit between the ACM and
the PAB On-Off Switch connector.
Is the resistance below 5.0 ohms on both circuits?

Repair the open Passenger Airbag MUX Switch circuit.
Perform AIRBAG VERIFICATION TEST - VER 1.

NOTE: When reconnecting Airbag system components, the ignition must be
turned off and the battery must be disconnected.

WARNING: TURN IGNITION OFF, DISCONNECT THE BATTERY AND WAIT
TWO MINUTES BEFORE PROCEEDING.
WARNING: IF THE AIRBAG CONTROL MODULE IS DROPPED AT ANY
TIME, IT MUST BE REPLACED.
If there are no possible causes remaining, view repair.

All

Repair

Replace the Airbag Control Module in accordance with Service
Instructions. WARNING: make sure the battery is disconnected
and wait 2 minutes before proceeding.

Symptom:

PASSENGER AIRBAG ON-OFF SWITCH SHORT TO BATTERY -
ACTIVE

When Monitored and Set Condition:

PASSENGER AIRBAG ON-OFF SWITCH SHORT TO BATTERY - ACTIVE

When Monitored:

When the ignition is 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

0.45 volts on the PAB MUX Switch circuit.

POSSIBLE CAUSES

PAB ON-OFF SWITCH CIRCUIT SHORTED

PAB ON-OFF SWITCH SHORT

PAB MUX SWITCH CIRCUITS SHORT TO BATTERY

ACM, PAB ON-OFF SWITCH CIRCUITS SHORT

When Monitored and Set Condition:

PASSENGER AIRBAG ON-OFF SWITCH SHORT TO GROUND - ACTIVE

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 low resistance, on the PAB MUX

Switch circuit.
