Test Ac: Left Seat Belt PRETENSIONER Circuit Resistance High Or Low (DTC B1885/B1877): Description

WARNING: This page is about a different car, the 2002 Lincoln Blackwood. However, it is still accessible from the selected car via links, so may be relevant.

Restraints Control Module (RCM) monitors left seat belt pretensioner circuit resistance at connector C2041A, terminals No. 18 (Light Green/Red wire) and No. 22 (Light Green/Black wire). If RCM detects resistance that is out of expected range (high or low), it will store Diagnostic Trouble Code (DTC) B1885 or 1877 in memory and flash Code 46 on AIR BAG warning light.
