Possible Causes

Right-side air bag circuit short to ground could be caused by short to ground in wiring harness, low resistance in right-side air bag module, or damaged or inoperative RCM.

1. Check right-side air bag module
   
   Turn ignition off. 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 B1997 is retrieved, go to next step. If DTC B1997 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. Repeat on-demand self-test.
2. Check right-side air bag module circuits
   
   Turn ignition off. Access RCM and disconnect harness connector C423. See RESTRAINTS CONTROL MODULE  under REMOVAL & INSTALLATION. Disconnect right-side air bag module simulator. Measure resistance between ground and RCM harness connector C423, terminal No. 23 (Green/Red wire). See Figure. Measure resistance between ground and RCM harness connector C423, terminal No. 24 (Black/Orange wire). If resistance is more than 10 k/ohms, replace RCM. Activate air bag system. See ACTIVATING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Clear DTCs. Repeat on-demand self-test. If resistance is less than 10 k/ohms, repair short to ground in Green/Red or Black/Orange wire. Activate air bag system. See ACTIVATING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Clear DTCs. Repeat on-demand self-test.
