Dodge Viper SRT-10 (ZB). Manual — part 297
Symptom:
NO PCI TRANSMISSION
When Monitored and Set Condition:
NO PCI TRANSMISSION
When Monitored:
With the ignition on and the module transmitting information on the
PCI BUS.
Set Condition:
The code will set if the onboard diagnostic cannot detect the module
transmitting information on the PCI BUS for 4 consecutive seconds. NOTE: Any PCI Bus
Failure will may cause a stored code to set.
POSSIBLE CAUSES
AIRBAG CONTROL MODULE - ACM
STORED CODE OR INTERMITTENT CONDITION
ACTIVE CODE PRESENT

NOTE: Ensure that the battery is fully charged.
IF THE MODULE IS DROPPED AT ANY TIME, IT MUST BE REPLACED.
Turn the ignition on.
From the list below, select the appropriate module and DTC type for the this
diagnostic trouble code.
NOTE: For the purpose of this test, the AECM and ORC modules will be
referred to as an ACM.
Select the appropriate module and type of DTC

With the DRBIII
t, record and erase all DTCs from all modules.
All active codes must be resolved before diagnosing any stored codes.
Maintain a safe distance from all airbags while performing the following steps.
With the DRBIII
t monitor active codes as you work through the system.
NOTE: If equipped with Passenger Airbag On-Off switch, read the DTC’s in
all switch positions.
Wiggle the wiring harness and connectors of the appropriate 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 DTC become active ?
All
Yes
→ Select appropriate symptom from Symptom List.
No
→ No problem found at this time. Erase all codes before returning
vehicle to customer.

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.
POSSIBLE CAUSES
PAB ON-OFF SWITCH OPEN
PASSENGER AIRBAG MUX SWITCH CIRCUITS OPEN
ACM, PASSENGER ON-OFF SWITCH CIRCUITS OPEN
STORED CODE OR INTERMITTENT CONDITION

SELECT ACTIVE or STORED DTC:
All
ACM - ACTIVE DTC
ACM - STORED DTC
NOTE: When reconnecting Airbag system components, the ignition must be
turned off and the battery must be disconnected.

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?
All
Yes
→ Go To 3
No
→ Replace the Passenger Airbag ON-OFF Switch.
Perform AIRBAG VERIFICATION TEST - VER 1.

TIME, IT MUST BE REPLACED. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT
AND PERSONAL INJURY OR DEATH.
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?
All
Yes
→ Go To 4
No
→ Repair the open Passenger Airbag MUX Switch circuit.
Perform AIRBAG VERIFICATION TEST - VER 1.
