PAB On/Off Switch Shorted to Battery (Active)
Test 1:
Tests 2 - 4:
SYMPTOM
PASSENGER AIRBAG ON - OFF SWITCH SHORT TO BATTERY - ACTIVE
WHEN MONITORED
When the ignition is ON, the MUX Switch Sense circuit supplies a 3 to 10 ms pulse every 100 ms across the switch resister to the MUX switch return circuit. Once the code is active, the ACM will disable the indicator for the duration of the ignition cycle.
SET CONDITION
The code will set if the ACM senses constant voltage over approximately 4.0 volts on the PAB MUX Switch circuits.
POSSIBLE CAUSES
- PAB ON-OFF switch circuit shorted
- PAB ON-OFF switch short
- PAB MUX switch circuits shorted to battery
- ACM, PAB ON-OFF switch circuits short
