Chrysler Pacifica. Manual — part 51
Symptom:
PASSENGER AIRBAG OFF INDICATOR CIRCUIT SHORT TO
GROUND
When Monitored and Set Condition:
PASSENGER AIRBAG OFF INDICATOR CIRCUIT SHORT TO GROUND
When Monitored:
When the ignition is on, the ACM monitors the PAB Indicator Driver
circuit for voltage on the PAB Off indicator circuit.
Set Condition:
The code will set if the ACM cannot detect voltage on the PAB Indicator
Driver circuit.
