Test B: DTC B1884 - PAD Warning Lamp Circuit Failure

PINPOINT TEST B: DTC B1884 - PAD WARNING LAMP CIRCUIT FAILURE

Normal Operation
When the ignition is in the ON position, the passenger air bag deactivation (PAD) indicator prove-out period is initiated by the restraints control module (RCM). The RCM briefly activates the PAD indicator (prove-out) to verify to the occupants correct functional operation of the PAD indicator.

During the PAD prove-out period, if the RCM detects an open (indicator does not illuminate) or short to ground (indicator illuminated continuously) on the PAD indicator circuit, it will store DTC B1884 in memory and send a message to the instrument cluster (IC) module to illuminate the air bag warning indicator.

- DTC B1884 PAD Warning Lamp Circuit Failure - If the RCM detects an open circuit or short to ground on the PAD indicator circuit, it will set this DTC.

This pinpoint test is intended to diagnose the following:
