Normal Operation

When the ignition is ON, the Restraints Control Module (RCM) briefly activates the Passenger Air Bag Deactivation (PAD) indicator to verify to the occupants correct functional operation.

If the RCM  detects an open or short to ground on the PAD  indicator circuit, it will store DTC B1884 in memory and send a message to the Instrument Cluster (IC) module to flash Lamp Fault Code (LFC) 18 on the air bag warning indicator. After the LFCs  are displayed, the air bag warning indicator will remain illuminated for the rest of the ignition cycle.

• DTC B1884 (PAD  Warning Lamp Circuit Failure) - If the RCM  detects an open or short to ground when the indicator is not active for greater than 2.2 seconds on the PAD  indicator circuit, it will set this DTC.

  This pinpoint test is intended to diagnose the following: 

• Wiring, terminals or connectors
• PAD  indicator
• RCM
