Possible Causes

Right front belt and buckle assembly pretensioner circuit shorted to ground can be caused by a short to ground on circuit No. 1081 (Yellow/Red wire) or circuit No. 1082 (Yellow/Black wire) or short to ground in right front belt and buckle assembly pretensioner.

1. Check for hard or intermittent DTC
   
   Turn ignition switch to OFF position. Connect scan tool to Data Link Connector (DLC). See USING SCAN TOOL  under DIAGNOSTICS. Turn ignition switch to RUN position. Retrieve and record any continuous DTCs. See RETRIEVING FAULT CODES  under DIAGNOSTICS. Perform on-demand self-test. See ON-DEMAND SELF-TEST  under DIAGNOSTICS. If DTC B1880 was retrieved during on-demand self-test, fault is hard. Go to next step. If DTC B1880 was not retrieved, fault is intermittent. Go to step  3 .
   NOTE: Do not separate or remove shorting bars from ECS module connector.
2. Check right front belt & buckle pretensioner circuit
   
   Turn ignition switch to OFF position. Disable air bag system. See DISABLING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Access and disconnect right front belt and buckle assembly pretensioner harness connector. See BELT & BUCKLE ASSEMBLY PRETENSIONER  under REMOVAL & INSTALLATION. Access and disconnect ECS module harness connector. See ELECTRONIC CRASH SENSOR (ECS) MODULE  under REMOVAL & INSTALLATION. Measure resistance between harness side of ECS module connector terminals No. 18 (Black/Light Blue wire, circuit No. 875) and No. 26 (Yellow/Red wire). See Figure . Measure resistance between harness side of ECS module connector terminals No. 18 (Black/Light Blue wire) and No. 27 (Yellow/Black wire). If resistance is less than 10 k/ohms in either circuit, inspect all crimps, terminals, fuses, wires and connectors in circuit No. 1081 (Yellow/Red wire) and circuit No. 1082 (Yellow/Black wire). See WIRING DIAGRAMS  . Check for pinched wires and damaged connector terminals. Repair any problems as necessary. Go to step  4 . If resistance is more than 10 k/ohms in both circuits, replace right front belt and buckle assembly pretensioner. Go to step  4 .
3. Check for intermittent fault
   
   Refer to continuous DTCs recorded in step  1 . If DTC retrieved in step  1 was an intermittent fault, check for causes of intermittent short to ground in circuits No. 1081 (Yellow/Red wire) and No. 1082 (Yellow/Black wire). See WIRING DIAGRAMS  . Attempt to recreate fault by flexing wire harness and cycling ignition key frequently. Repair any intermittent problems. Go to next step. If no intermittent problems are found, replace ECS module. Go to next step.
4. Check for additional DTCs
   
   Refer to continuous DTCs recorded in step  1 . If any continuous DTCs were retrieved, go to diagnostic trouble code identification table for direction to appropriate test. See DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION  table. DO NOT clear any DTCs until all DTCs have been resolved. If no continuous DTCs were retrieved, reconnect air bag system. Activate air bag system. See ACTIVATING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Clear all DTCs. See CLEARING FAULT CODES  under DIAGNOSTICS.
