Possible Causes

A right side air bag circuit short to battery ground could be caused by a short to battery on Green-Red wire (circuit 15S-JA15), a short to battery on Black-Orange wire (circuit 91S-JA15), a short to battery in right side air bag module or an RCM internal fault.

1. Check right side air bag
   
   Turn ignition switch to OFF position. Disable air bag system. See DISABLING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Turn ignition switch to RUN position. Perform on-demand self-test. See ON-DEMAND SELF-TEST  under DIAGNOSTICS. If DTC B1996 is retrieved, go to next step. If DTC B1996 is not retrieved, replace right side air bag module. See SIDE AIR BAG MODULE  under REMOVAL & INSTALLATION. Activate air bag system. See ACTIVATING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Clear DTCs. See CLEARING FAULT CODES  under DIAGNOSTICS. Repeat on-demand self-test.
2. Check right side air bag module circuit
   
   Turn ignition switch to OFF position. Access RCM and disconnect harness connector C423. See RESTRAINTS CONTROL MODULE (RCM)  under REMOVAL & INSTALLATION. Disconnect right side air bag simulator. Turn ignition switch to RUN position. Measure voltage between ground and RCM harness connector C423, terminals No. 23 (Green-Red wire). See Figure. Measure voltage between ground and RCM harness connector C423, terminals No. 24 (Black-Orange wire). If any voltage is present, repair Green-Red or Black-Orange wire as necessary. See WIRING DIAGRAMS . Activate air bag system. See ACTIVATING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Clear DTCs. Repeat on-demand self-test. If no voltage is present, replace RCM. Activate air bag system. Clear DTCs. Repeat on-demand self-test.
