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 4
No
→ Replace the Passenger Airbag ON-OFF Switch.
Perform AIRBAG VERIFICATION TEST - VER 1.

WARNING: IF THE AIRBAG CONTROL MODULE IS DROPPED AT ANY
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 circuit between the PAB
On-Off Switch connector and ground.
Is the resistance below 10K ohms?
All
Yes
→ Repair the Passenger Airbag MUX Switch Sense circuit shorted to
ground.
Perform AIRBAG VERIFICATION TEST - VER 1.
No
→ Go To 5
5
Measure the resistance between the PAB MUX Switch Sense circuit and the PAB
MUX Switch Return circuit at the PAB On-Off Switch connector.
Is the resistance on either circuits below 10K ohms?
All
Yes
→ Repair the Passenger Airbag MUX Switch circuits shorted to-
gether.
Perform AIRBAG VERIFICATION TEST - VER 1.
No
→ Go To 6

WARNING: TO AVOID PERSONAL INJURY OR DEATH, 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. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT
AND PERSONAL INJURY OR DEATH.
If there are no possible causes remaining, view repair.

NOTE: Ensure the battery is fully charged.
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 OFF INDICATOR CIRCUIT SHORT TO BATTERY
When Monitored and Set Condition:
PASSENGER OFF INDICATOR CIRCUIT SHORT TO BATTERY
When Monitored:
When the ignition is on, the ACM monitors the PAB Indicator Driver
circuit for voltage from the PAB On - off Indicator circuit.
Set Condition:
The code will set if the ACM senses battery voltage on the PAB Indicator
Driver circuit.
POSSIBLE CAUSES
SHORTED GAUGE CLUSTER CIRCUITS
PAB INDICATOR CIRCUIT SHORT TO BATTERY
ACM, PASSENGER INDICATOR DRIVE CIRCUIT SHORTED TO BATTERY
