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

Symptom:

PASSENGER AIRBAG ON-OFF SWITCH OPEN - ACTIVE

When Monitored and Set Condition:

PASSENGER AIRBAG ON-OFF SWITCH OPEN - 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 an open or high resistance over, 1275.0

on the PAB MUX Switch sense circuit.

POSSIBLE CAUSES

CONFIGURE ACM FOR ON-OFF SWITCH

PAB ON-OFF SWITCH OPEN
