Dodge Dakota (R1). Manual — part 6
PASSENGER AIRBAG ON-OFF SWITCH OPEN - STORED
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 in the PAB
MUX Switch Sense circuit or PAB MUX Switch Return circuit.
PASSENGER AIRBAG ON-OFF SWITCH SHORT TO BATTERY - STORED
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.
PASSENGER AIRBAG ON-OFF SWITCH SHORT TO GROUND - STORED
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 Sense circuit.
PASSENGER SBT CIRCUIT OPEN - STORED
When Monitored:
When the ignition is on, the ACM monitors the resistance of the
Passenger Seat Belt Tensioner circuits.
Set Condition:
The ACM detected an open circuit or high resistance across the Passenger
Seat Belt Tensioner circuits.
PASSENGER SBT CIRCUIT SHORT - STORED
When Monitored:
When the ignition is on, the ACM monitors the resistance of the
Passenger Seat Belt Tensioner circuits.
Set Condition:
The ACM has detected low resistance in the Passenger Seat Belt
Tensioner circuits.
PASSENGER SBT SHORT TO BATTERY - STORED
When Monitored:
When the ignition is on, the ACM monitors the voltage of the Passenger
Seat Belt Tensioner circuits.
Set Condition:
The ACM has detected high voltage on the Passenger Seat Belt Tensioner
circuits.
PASSENGER SBT SHORT TO GROUND - STORED
When Monitored:
When the ignition is on, the ACM monitors the resistance of the
Passenger Seat Belt Tensioner circuits for low resistance.
Set Condition:
The ACM detected a short to ground in the Passenger Seat Belt Tensioner
circuits.

PASSENGER SQUIB CIRCUIT OPEN - STORED
When Monitored:
With the ignition is On, the ACM monitors the resistance of the
Passenger Squib circuits.
Set Condition:
The ACM has detected an open circuit or high resistance across the Driver
Squib circuits.
PASSENGER SQUIB CIRCUIT SHORT - STORED
When Monitored:
When the ignition is on, the ACM monitors the resistance of the
Passenger Squib circuits.
Set Condition:
The ACM has detected low resistance in the Passenger Squib circuits.
PASSENGER SQUIB SHORT TO BATTERY - STORED
When Monitored:
When the ignition is on, the ACM monitors the voltage of the Passenger
Squib circuits.
Set Condition:
The ACM has detected high voltage on the Passenger Squib circuits.
PASSENGER SQUIB SHORT TO GROUND - STORED
When Monitored:
Continuously with the ignition on.
Set Condition:
The ACM has detected a short to ground in the Passenger Squib circuits.
WARNING LAMP CIRCUIT OPEN - STORED
When Monitored:
When the ignition is On, the ACM monitors the PCI Bus for a message
from the MIC containing the airbag warning lamp status Ok or Open. The MIC transmit
the message one time per second in response to the ACM lamp On/Off message.
Set Condition:
The code is set if the lamp state is open for 2 consecutive messages.
WARNING LAMP CIRCUIT SHORT - STORED
When Monitored:
When the ignition is On, the ACM monitors the PCI Bus for a message
from the MIC containing the airbag warning lamp status Ok, Open, or Short. The MIC
transmit the message one time per second in response to the ACM lamp On/Off message.
Set Condition:
The code is set if the lamp status is SHORT for 2 consecutive messages.

NOTE: Ensure the battery is fully charged.
Active codes must be resolved before diagnosing stored codes.
Turn the ignition on.
With the DRBIII
t, record and erase all DTCs from all modules.
With the DRBIII
t monitor active codes as you work through the system.
Wiggle the wiring harness and connectors of the Airbag System and rotate the
steering wheel from stop to stop.
NOTE: Check connectors - Clean and repair as necessary.
You have just attempted to simulate the condition that initially set the trouble code
message.
The following additional checks may assist you in identifying a possible intermittent
problem:
- Visually inspect related wire harness connectors. Look for broken, bent, pushed out,
spread, corroded, or contaminated terminals.
- Visually inspect the related harnesses. Look for chafed, pierced, pinched or partially
broken wire.
- Refer to Wiring Diagrams and Technical Service Bulletins that may apply.
Did the DTCs become active?
All
Yes
→
Select appropriate active symptom from Symptom List.
No
→
No problem found at this time. Erase all codes before returning
vehicle to customer.
