Possible Causes

Right side crash sensor malfunction can be caused by open or short circuit in wiring harness between right side crash sensor and SAS control module, right side crash sensor malfunction or SAS control module malfunction.

1. Inspect right side crash sensor
   
   Turn ignition to LOCK position. Disconnect negative battery cable and wait at least one minute. Disconnect right side crash sensor harness connector and inspect connector. If right side crash sensor connector is damaged, replace air bag system wiring harness. If right side crash sensor connector is not damaged, go to next step.
2. Inspect wiring harness between right side crash sensor & SAS control module
   
   Turn ignition to LOCK position. Disable air bag system. See DISABLING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Disconnect right side crash sensor. See SIDE CRASH SENSOR  under REMOVAL & INSTALLATION. Check for short to ground, short to power or open circuit between SAS control module connector No. 2, terminal No. 2B and right side crash sensor connector terminal "A". See Figure & Figure . Check for short to ground, short to power or open circuit between SAS control module connector No. 2, terminal No. 2C and right side crash sensor connector terminal "B". If short to ground, short to power or open circuit is detected, replace air bag system wiring harness. If short to power or open circuit is not detected, replace right side crash sensor. See SIDE CRASH SENSOR  under REMOVAL & INSTALLATION. Go to next step.
3. Inspect SAS control module
   
   Turn ignition switch to LOCK position. Disable air bag system. Connect all SAS control module connectors. Connect right side crash sensor connector. Connect negative battery cable. Retrieve Diagnostic Trouble Codes (DTCs). See RETRIEVING DIAGNOSTIC TROUBLE CODES (DTCS)  under DIAGNOSTICS. If DTCs B2445 and/or U2018 are retrieved, replace SAS control module. If DTCs B2445 and/or U2018 are not retrieved, test is complete.
