Circuit Test N - Code 41, Open Front Impact Sensor Circuit

NOTE: Before proceeding, follow air bag service precautions. See SERVICE PRECAUTIONS . After repairs are performed, recheck AIR BAG warning light for other fault codes. Perform system operation check. See TESTING - SYSTEM OPERATION CHECK .

INITIAL TEST PROCEDURE - Deactivate SRS. See COMPLETE SYSTEM DEACTIVATION under DISABLING & ACTIVATING AIR BAG SYSTEM. Disconnect diagnostic monitor. See Figure . Check resistance between terminal No. 17 (Pink/Orange wire) of diagnostic monitor Gray connector and ground and terminal No. 19 (Yellow/White wire) of diagnostic monitor Gray connector and ground. See Figure . If resistance is more than 825 ohms in both circuits, go to step 2). If resistance is less than 825 ohms in either circuit, replace diagnostic monitor. When repairs are complete, check AIR BAG warning light for codes with Air Bag Simulator(s) (105-00008) still in place of air bag module(s). See TESTING - SYSTEM OPERATION CHECK . If system checks okay, reactivate SRS.
VERIFY OPEN IN FRONT IMPACT SENSOR - Disconnect front impact sensor(s) that had resistance of more than 825 ohms in step 1). Check resistance between sensor terminals. If resistance is more than 825 ohms, replace sensor. Reconnect all disconnected SRS connectors. When repairs are complete, check AIR BAG warning light for codes with Air Bag Simulator(s) (105-00008) still in place of air bag module(s). See TESTING - SYSTEM OPERATION CHECK . If system checks okay, reactivate SRS. If resistance is less than 825 ohms, locate and repair open in circuits No. 617 (Pink/Orange wire) and/or 621 (Yellow/White wire) in wiring harness. Reconnect all disconnected SRS connectors. When repairs are complete, check AIR BAG warning light for codes with Air Bag Simulator(s) (105-00008) still in place of air bag module(s). See TESTING - SYSTEM OPERATION CHECK . If system checks okay, reactivate SRS.
