SYMPTOM
PASSENGER AIRBAG ON - OFF SWITCH SHORT TO GROUND - ACTIVE
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.
POSSIBLE CAUSES
- PAB ON-OFF switch circuit shorted
- PAB ON-OFF switch short
- PAB MUX switch circuits short to ground
- PAB MUX switch circuits shorted together
- ACM, PAB ON-OFF switch circuits short to ground
