Symptom:
PAB OFF INDICATOR CIRCUIT SHORT OR SHORT TO BATTERY -
ACTIVE
When Monitored and Set Condition:
PAB OFF INDICATOR CIRCUIT SHORT OR SHORT TO BATTERY - ACTIVE
When Monitored:
When the ignition is on, the ACM monitors the PAB Indicator Driver
circuit for voltage from the PAB On-Off Switch indicator.
Set Condition:
The code will set if the ACM senses battery voltage on the PAB Indicator
Driver circuit.
POSSIBLE CAUSES
PASSENGER AIRBAG INDICATOR SHORT TO FUSED RUN-START CIRCUIT
PAB ON-OFF SWITCH INDICATOR SHORT
PASSENGER AIRBAG INDICATOR DRIVER CIRCUIT SHORTED TO BATTERY
ACM, PAB INDICATOR DRIVER CIRCUIT SHORT TO BATTERY
