DTC B1932 - High Resistance Or Open In Driver-Side Air Bag Circuit
WARNING: This page is about a different car, the 1996 Ford Ranger and 1996 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Before proceeding, see SERVICE PRECAUTIONS . After servicing has been performed, recheck AIR BAG warning light. If system is okay, install air bag modules and reactivate air bag system.
- Verify Condition
Connect NGS tester to DLC. Perform ON-DEMAND SELF-TEST. If DTC B1932 is retrieved, go to step 2). If DTC B1932 is not retrieved, go to step 6). - Check Circuit Resistance
Deactivate air bag system. See COMPLETE SYSTEM DEACTIVATION under DISABLING & ACTIVATING AIR BAG SYSTEM . Connect NGS tester to DLC. Perform ON-DEMAND SELF-TEST. If DTC B1932 is retrieved, go to next step. If DTC B1932 is not retrieved, go to step 9). - Check Circuit 614
Reconnect diagnostic monitor. Set ohmmeter to lowest scale (200k/ohms or AUTO). Zero ohmmeter by touching leads together. Record resistance reading. Remove plastic locking wedge from Gray harness connector at air bag diagnostic monitor. Measure resistance between diagnostic monitor connector terminal C1-2 and C1-3. See Figure. Subtract reading found when zeroing ohmmeter. If resistance is less than 3 ohms, replace air bag diagnostic monitor. Reconnect system. Verify system. Go to step 9). If resistance is more than 3 ohms, go to next step. - Isolate Resistance
Disconnect clockspring connector at base of steering column. Connect air bag simulator to harness connector at base of steering column. Zero ohmmeter by touching leads together and record reading. Measure resistance between diagnostic monitor harness connector terminals C1-2 and C1-3. See Figure. Subtract reading found when zeroing ohmmeter. If resistance is less than 2.2 ohms, replace clockspring. Reconnect system. Verify system. Reactivate system and go to step 9). If resistance is more than 2.2 ohms, go to next step. - Check Circuit 614 For Open
Use ohmmeter to connect one lead to circuit 614 (Gray/Orange wire) at air bag clockspring harness connector. Connect second lead to terminal C1-2. If resistance is less than 3 ohms, repair circuit 615 (Gray/White wire) for open. Reconnect system. Verify system. Reactivate system. Go to step 9). If resistance is more than 3 ohms, repair circuit 614 (Gray/Yellow wire) for open. Reconnect system. Verify system. Reactivate system. Go to step 9). - Check For DTC Service
Deactivate system. See COMPLETE SYSTEM DEACTIVATION .If DTC B1932 has just been repaired, go to step 9). If DTC B1932 has not just been repaired, go to next step. - Check Air Bag Connections
Disconnect air bag diagnostic monitor. Set ohmmeter to lowest scale (200K ohms or AUTO). Zero ohmmeter by touching leads together and record reading. Remove plastic locking wedge from Gray harness side connector at base of steering column. See Figure. Measure resistance between diagnostic monitor harness connector terminals C1-2 and C1-3 while wiggling wires at driver-side air bag module connector where it mates to clockspring. Subtract reading found when zeroing ohmmeter. If resistance is more than 3 ohms or other problems are noted, replace clockspring. Go to step 9). If resistance is less than 3 ohms, Go to next step. - Check Circuits 614 and 615
Inspect circuit 614 (Gray/Yellow wire)and 615 (Gray/White wire) for pinched or chafed wires leading to high resistance. If problems are noted, repair as necessary and go to next step). If no problems are noted, go to next step. - Check For Other DTCs
Connect NGS to DLC. If other DTCs are retrieved go to proper DTC test. If no other DTCs are retrieved, reactivate system and clear all DTCs.
