Normal Operation
The air bag Electronic Crash Sensor (ECS) module checks for passenger air bag circuit shorts to ground by monitoring the voltage of circuits 943 (YE/RD) and 944 (RD) at pins 14 and 28. If the ECS 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 air bag circuit shorted to ground could be caused by:

  • a short to ground on circuit 943 (YE/RD).
  • a short to ground on circuit 944 (RD).
  • a short to ground on the passenger air bag module.
