LFC 16 / DTC B1888 (Steps 1 - 5):

LFC 16 / DTC B1888 (Step 6):

Normal Operation
The air bag diagnostic monitor checks for passenger- side air bag circuit shorts to ground by monitoring the voltage of the (LB/O) wire and pins 14 and 28 (P/B). If the air bag diagnostic monitor detects a short to ground on either of these pins, it will store a diagnostic trouble code (DTC) B1888 in memory and flash a lamp fault code (LFC) 16 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
A passenger-side air bag circuit short to ground could be caused by:
- A short to ground on (LB/O) wire.
- A short to ground on (P/B) wire.
- A short to ground on the passenger-side air bag module.
- Air bag diagnostic monitor internal concern.
